|Handmade Japanese Katana Sword With Golden Blade And Tsuba|
My order came out beautifully. Very pleased with it. My only question is whether the swords are really battle-ready or not because the website says they are but the pamplet that comes with the swords says not to use them to cut, slice and that they are for display over. I bought these as backup weapons to my guns so if they aren't battle ready that would defeat the point. But they are beautiful indeed!!!

The Swords forged with Spirit of Japan
Katana (Samurai Sword) is a generic term for swords forged in the originally developed way in Japan. They are classified as Katana (Tachi, Uchigatana), Wakizashi and Tanto depending on size. Craftsmen who make Katana are called 'Toko (sword craftsman),' 'Tosho (sword master)' or 'Katana kaji (swordsmith).
The Very Soul of the Samurai
Its beautiful shape has symbolic meaning as well as its use as a weapon since ancient times, and many are highly appraised as art objects. Old and unbroken lines, including the Imperial family and shrines, value treasure swords (such as Amenomurakumono tsurugi) as a proof of power. They also functioned as a support pillar of spiritual culture, 'the very soul of the samurai against the backdrop of the military government. They feature a process of folding and forging' two types of metal, hard brittle steel and soft iron, so the Toshin (body of blade) and Nakago (core) are combined together. The Nakago has holes (Mekugi holes) to fix the body of blade to the Tsuka (handle) with pin fasteners.
Katana is not only a Weapon, but also an Art-craft
Different from swords of other countries, the biggest feature of Katana is that the body of blade itself has artistic value, aside from the fittings (Koshirae). Katana is found in a poem titled 'A Poem About the Katana' by Ou-yang Hsui in Baisong. This poem describes a merchant of Yueh (South China) who goes to Japan to buy Katana already being called treasure swords given their artistic qualities found in the fittings and appearance. Although the main point of A poem About the Katana' is to lament that books already lost in China still exist in Japan, and not about Katana, it shows that the beauty of Katana was already recognized by overseas curiosos from the late Heian period to the early Kamakura period as one of Japan's exports.
Not to Break and Not Bend
It is thought that the process of creation of Katana has been developed basically in order to achieve three conflicting natures, 'Not to break, not bend, and sharply cut' simultaneously. In the modern metallurgy, 'not break and not bend' is called 'compatibility of strength and tenacity' and improvement research of structural material has still being done night and day. Because saving trouble even a little makes this compatibility balance lost.
Not to Break and Sharply Cut
Also, 'sharply cut' and 'not break' are difficult to be compatible. This has been realized by having so-called functionally-gradated structure that the cutting edge is hard, and the hardness is gradually decreased to the core, which makes compressive residual stress generate at the cutting edge. The explanation above is a case showing that the ideal condition is realized in the whole blade, so in fact, invisible defects can make a sword easily broken. However, a Katana in the ideal condition is called 'the world's strongest cutting tool,' and with reason. The sharpness of Katana are stated everywhere. As a notable example, 'Kabuto-wari (helmet splitting)' with Katana by the Dotanuki group led by Kenkichi SAKAKIBARA is famous. With best pieces of katana, if you drop one sheet of paper on it, it will be cut by its weight.
Katana is specialized for 'Cut Off'
katanaA Katana is not really light if you compare in the blade length, because its handle is longer than other swords. However, among the swords for double-handed use, it is one of the lightest ones. A Katana is originally suitable to 'cut off.' However, it is necessary to slide and pull when cutting so that the direction of force is added at a right angle against the object to cut, because the sword itself is light. With the same reason, when sharpening a sword to 'cut and kill,' it is sharpened in the direction to slide like a kitchen knife (similar in the way to handle double-edged sword). Tracing the history, from the Kofun period to the Nara period, when swords became separated between ceremonial use and actual use, 'Keito Tachi' and 'Kurozukuri-no Tachi' were only for 'cutting off.' In the Heian period, 'Kogarasu' adopted 'Kissaki moroha-zukuri (double edged tip style)' to be suitable also to 'stab,' but later, Tachi and Uchigatana didn't adopt Kissaki moroha-zukuri and had a curve to be suitable to 'cut' by wristing.
Values and Roles of Katana
It is quite an abnormal situation when people fight risking their lives, not just in battle, and they need to have a special determination. In such time, it is no wonder that 'the very soul of the samurai' of Katana, the mental and religious value as sacred treasures and the artistic value are needed as realistic force, in a way. There exist a lot of swords made during the war-torn period that are engraved with names of Shinto and Buddhist deities the owners believed in or with mantra, which interestingly reflects warriors' naked feelings. From the engineering aspect, in the periods when the theory of metallic crystal or phase transition was not resolved, sword craftsmen kept making an effort and achieved cutting tools that were excellent scientifically as well, which attracts much interest even now. This is because engineering control in the black box style is realized by accumulating and transmitting lots of meta-information including apparent change, texture, and smell that are not theorized or verbalized. In fact we don't interpret people's expression by fine and strict definition, but have an advanced ability to 'read the mind,' and especially since the Japanese are excellent in this ability, attempts to use Japanese manufacturing as an engineering system has begun in recent years.
Tatara-buki method; the type of steel used to make a Katana is called Japanese steel or Tamahagane. Tamahagane is made using the 'Tatara-buki method,' an original Japanese steel making process. Not depending upon iron ore imported from other countries, using black iron sand found on beaches in Japan, achieves fast reduction at low temperature, and creates high-quality steel with few impurities, compared to the modern steelmaking processes.
Tatara-buki is a traditional Japanese technique that is essential to the making of Japanese swords. However, in 1925, the fires of Japan’s tatara (furnaces) were all extinguished. In order to preserve Japanese swords as important works of art and cultural assets, Nittoho Furnace was restored and began operating again in 1977. Technicians and a supervisor known as a murage, who is well-versed in the furnace’s construction and operating method, still work at Nittoho Furnace, and produce Japanese swords using the traditional technique.
Heated Tamahagane is hammered with a Tsuchi (hammer) to make a thin flat plate. When qenched in water and rapidly cooled, the excess carbon flakes off. This is called 'Mizuheshi' (removal of carbon using water). These are raw metal making processes called Heshi (removal process).
This case-hardened piece is called Heshi gane (removed metal), which is broken into small metal pieces using a Tsuchi (hammer). These metal pieces are stacked on the tip of a forging tool called 'Teko', and wrapped in Japanese traditional paper. Straw ash is applied, and then coated with clay slurry, then it goes into the furnace (Hodo) to heat until the clay surface melts. The straw ash and clay prevents scaling loss of the steel during heating and oxidizing. It is then hammered with a Kozuchi (light hammer) to form 6x9cm block. If there are not enough iron pieces, more are stacked, heated, hammered with a Kozuchi, and formed into an ingot weighing 1.8kg to 2.0kg. This is the process known as 'Tsumi wakashi' (stacked and heated). Other than Tamahagane, pig iron (Sentetsu) which contains a lot of carbon, and pure iron called Hocho tetsu also undergo Tsumi wakashi and Shita-gitae processing mentioned below.
The red-hot block is struck and elongated using a Tsuchi (hammer), and folded back into the middle of its length, which is called a 'folding method of forging' and it is done repeatedly. In fact, the word 'Muko-zuchi,' describes the method by which Tosho (Yokoza, master) and his disciple (Sente, helper) alternately strike the body of the blade with a Tsuchi, and this has become the root of the word 'Aizuchi wo utsu (chiming in).' In this step, folding is done about five or six times.
After finishing Shita-gitae with three types of steel, Tamahagane (literally "jeweled steel"), Sentetsu (pig iron), and Hocho tetsu (literally "kitchen knife steel," pure iron), they are hammered using a Kozuchi (light hammer) again to make metal pieces, selected to produce the proper steel composition, they are stacked and formed like the first Tsumi wakashi. In this step, four kinds of steel having different carbon content, Shingane (center metal), Munegane (back metal), Hanokane (blade metal) and Gawagane (side metal), are made.
Shingane are folded back 7 times, Munegane 9 times, Hanokane 15 times and Gawagane 12 times. By repeatedly forging after folding back the steel struck and elongated, impurities such as sulfur, excess carbon and non-metal impurities are removed, and a strong and homogeneous steel is created.
After getting four kinds of steel, Shingane (center metal), Munegane (back metal), Hanokane (blade metal) and Gawagane (side metal) by Shita-gitae (forging), the second Tsumi wakashi (stacked and heated metal) and Age-gitae (finishing forging), three layers of Munegane, Shingane and Hanokane are forged and welded, and struck and elongated to get four times the material, 20mm thick, 40mm wide, and 90mm long, and then cut into four. This is called the 'Core metal (芯金).' Gawagane is also heated, and struck and elongated to become twice as long as the Core metal, and is then cut in the center to make two Gawagane of the same length as the Core metal. Gawagane, Core metal and the other Gawagane are stacked in this order, heated, forged, and welded, then struck and elongated into a 15mm thick, 30mm wide, 500 to 600mm long plate. Teko' is cut off, then 'Nakago' which becomes the grip of a sword is heated, forged and welded.
Sunobe,' is done by striking and elongating to form the shape of the Katana, and Kissaki (piercing tip) is made by cutting off the end. Since this rough shape determines the final finished shape of a Katana, it is carefully formed by striking with a Kozuchi.
Mune (back) of the blade is struck to start the base of a triangular shape, and the blade side (Hirachi) is struck and elongated to reduce thickness. Then the Mune of the Nakago is struck to round the back edge, and lastly 'Shinogichi (ridge line)' is struck and formed. The whole body of the blade is heated at a lower temperature until it becomes reddish brown.
After it cools down, the black taint is removed by grinding with a rough polishing stone, and the Hirachi (blade) and Shinogichi (ridge line) are hammered using a Kozuchi (light hammer), and cold forging process is applied. The straight lines of Mune and blade are adjusted, and unevenness is shaved with a special plane for shaving metal called Sen (銑, with the radical of 金 and 舌, by right). In this step, 'Hawatari (length of the blade) and the 'Machi (notch)' is determined.
Namatogi' is done to grind out the shaving marks left by using the plane and this is done using a polishing stone. Then, after oil and fat are removed using straw ash with water, and the sword is dried.
As preparation for 'Yaki-ire (quenching)' to rapidly cool the heated blade with water or other liquid, 'Tsuchioki (soil coating)' where three types of Yakiba-tsuchi soil (soil used for quenching) are applied to the Hirachi (blade), Hamon (blade pattern) and Shinogichi (ridge line) are done. Yakiba-tsuchi soil (soil used for quenching) is applied thinly and evenly over the Hirachi (blade side), then Hamon (blade pattern) is designed with a writing brush using Yakiba-tsuchi soil for quenching for Hamon. Lastly, a thicker coating of Yakiba-tsuchi soil (for quenching) is applied for the Shinogichi (ridge line) from the Hamon (blade pattern) to Mune (back). By using thicker concentration of Yakiba-tsuchi soil, for quenching, on the Shinogichi (ridge line), when cooling rapidly by Yaki-ire, the blade side is quickly cooled and quenched completely, and the Mune side is cooled relatively slowly and not fully quenched. Quenching makes a sword harder, the metal expands, and creates the distinct curve of a Katana. The Mune expands less, and takes on the property of tenacity rather than hardness, and this supports the blade side steel which is hard, but otherwise easily broken.
Generally during Yaki-ire, Tosho dims the light of the workshop, and judges the temperature of steel by its glow. The blade coated with Tsuchioki is inserted deeply into the Hodo, and the whole blade from end to end is heated uniformly to about 800 degrees. The temperature is most important, and the optimal heat condition is checked with the greatest care, the body of blade is then plunged swiftly to a water tank and rapidly cooled. As mentioned above, the blade warps in the water, and it is pulled out after it is fully cooled, and is then ground with a rough polishing stone, and the Yakiba (焼刃, cutting edge) is checked. After that, the blade is reheated in a charcoal fire for 'Yaki-modoshi (tempering).' This work is called 'Aitori (neutralizing).' Since it also warps to the side a little, it is struck while on a wooden base with a Kozuchi (light hammer) to adjust straighten the blade. The Nakago (core) is also tempered and formed. After Yaki-ire (quenching), the surface of the blade is very hard and this is called Martensite. Depending on how the Martensite looks, the Hamon (blade pattern) that looks like round particles on the surface of the metal to the naked eye, is called Nie (literally "boiling"), and separates from the Nioi (literally "scent") that looks like fine lines because the individual particles cannot be distinguished. Other than water, some of other cutting tools are quenched in oil, and as were Japanese military swords during the war, but today, it seems to be reare that a Katana is quenched in oil. Although quenching in oil reduces failure, it is not suitable for modern swords that are meant to become a work of art because it cannot achieve a fine Hamon (blade pattern).
The sword craftsman modifies the curvature of the Katana after Yaki-ire (quenching) is finished, and does a rough grinding. In this step, final adjustment is done by checking for small scratches, blade thickness and Jiba (blade surface).
Nakago (core) is finished with a Sen (a grinding tool) or a file, and for a Mekugi (fastening pin) hole used for securing the Tsuka (handle grip), usually one hole is drilled and two for a sword used for Iaido (Japanese martial art). Then, Yasurime (to prevent hands from slipping on the grip), which is unique to sword craftsmanship, is added.
The craftsman carves his own name, address or year the sword was made on into the Nakago (core) as Mei (an inscription) with a Tagane (borer). Generally, the name and address of the sword craftsman are inscribed on the front side (outside when wearing Tachi or Katana), and the year or name of the owner in the back side, but there are exceptions such as back-inscription or no inscription at all. This is the end of the work for the sword craftsman, then a Togi-shi (polisher) polishes the sword finally, but before the Muromachi period, the sword craftsman himself also polished the sword. There is a big differences in polishing Katana compared to other cutting tools; ensuring ornamental elements of a Katana, as a craftwork, is focused on as well as assuming sharpness as a cutting tool, and the whole body, not just the blade part, is polished.
After all the process of forging, Saya-shi (Sheath craftsman) creates the Saya (sheath) appropriate to the Katana. Katana are not completed soley by a sword craftsman, other craftsmen including a Togi-shi (polisher) and Saya-shi (Sheath craftsman) add the finishing touches.
The katana is generally defined as the standard-sized, moderately curved Japanese sword with a blade length greater than 23.86 inches. It is characterized by its distinctive appearance: a curved, slender, single-edged blade with a circular or squared guard and long grip to accommodate two hands.
Western historians have said that the katana was among the finest cutting weapons in world military history.
Having a regular cleaning routine in place is key to maintaining your katana.
You can purchase a traditional sword cleaning kit that will have everything you need. There are three steps: removing oil, polishing the blade, and oiling the blade.
Using a sheet of rice paper from the kit or soft cotton cloth, remove any oil that is still on the blade from the previous maintenance. Take the powder ball and tap it lightly against the blade about every two inches or so along its length. Take a fresh piece of rice paper and rub the powder over the blade to polish it. Do this until both sides of the blade have been polished and the powder completely removed. Take the bottle of oil and apply a few drops along the length of the blade on each side. Use a fresh piece of rice paper to spread the oil evenly on the blade.
The most iconic and well known of all the Samurai swords; the katana is distinguished by its long blade and handle that is made to accommodate two hands and strike from a large distance. It has a curved, slender, single-edged blade with a circular or squared guard. The katana has a set of dimensions that separate it from other samurai swords. A traditional katana will measure 3 to 4 feet in total length, with the hilt taking up one-fourth of the total and a characteristic curvature of more or less than 1 inch.
A full tang katana is the sword where the tang extends to almost the whole length of the handle, which makes the blade and the handle the same piece of metal. This gives to the sword certain rigidity and makes it a very solid piece to enjoy.
Full Tang katanas are handmade swords. They can be made of various stainless-steel types according to the Carbon Concentration. The forging is the essential part of the production because it allows the samurai sword to be solid and relatively light. Commonly, the piece of metal is repeatedly heated by fire and hammered while the metal is being folded. The mounting of the different parts is a very delicate operation that has its origins deep in the Japanese civilization. Samurai are used to cherish their Katanas as their trusted partners, and they handle them with love and care.
Clay tempered katana are swords made according to a particular process of blade reinforcement. During the forging, there are steps to go through involving several steps and some compounds mixture, used by the entire swords forger, yet each has its own formula. The compound mixture is none but Clay recipe that each forger has a secret ingredients list. Clay tempering is supposed to be an art more than a sword works. Clay tempered katanas are said to be more resistant and durable. Clay treatment must be operated by professionals to be efficient. Also, each steel type is supposed to be responsive to different clay compositions.
Traditionally, Carbon Steel is obtained by firing up a particular type of charcoal within a Clay Tub for approximately 72 hours. Iron powder should be added at determined amounts to associate appropriate quantity of Carbon. At the end, the obtained Steel is Stainless; its solidity depends on the amount of Carbon that associates to Iron. The steel obtained is referred to by four digits number which designates Carbon by the two first digits and the percentage of Carbon within the steel. Thus, 1045 Carbon steel refers to Carbon steel material that contains 0.45% Carbon fraction. It is called Medium Carbon Steel as well because that carbon concentration is the minimal required for the Steel to be used for industrial purposes; there are lower concentrations of carbon, but the materials are not suited for industrial use. 1045 Carbon Steel is suited for making katanas because it is cheaper than the other materials used for this industry. It is softer and easily forged. The proper application of the hardening techniques and the Clay treatment, certainly produce amazing steel that can be forged in real pieces of arts.
1060 Carbon Steel is a high carbon steel. The number 1060 refers to a material made of an alloy of Iron with a Carbon tenor of about 0.60%. Other elements can be found mixed to this alloy, but their tenors are not very significant. 1060 Carbon Steel Is harder than 1045 Carbon Steel; this property makes this steel harder to forge. The high Caron tenor makes the 1060 Steel more durable, but it is not high enough to compromise its pliability. The swords made of 1060 Carbon Steel keep their edges sharp longer and they are more expensive. It is the favorite steel material of famous swords companies.
1060 Carbon Steel katanas inherit the durability and the hardness of the steel material. 1060 Carbon Steel Katanas require more effort to produce. The edge is durable, and the sharpness lasts longer. It is more resistant to corrosion and oxidation and therefore requires less maintenance processing than the 1045 Katanas. Though, it is very important to clean the blade and polish it after every extensive use to ensure the durability and the sharpness, and to keep the edge healthy. 1060 Carbon Steel Katanas are expected to be heavier than those made of 1045 Carbon Steel, because of the steel properties. These Katanas create curves while being forged. This is the property of high and medium Carbon Steels: they keep a certain softness which makes them to develop ideal curves during the clay tempering processes and folding operation. The differential hardening and the folding operations, which are meant to harden the blade can increase the weight of the piece; this situation is handled by an aesthetically implanted blood groove that help eliminate the extra weight but keep the resulting spine from the differential Clay Tempering process.
1060 Carbon Steel Katanas have the medium rank between 1045 and 1095 Carbon Steel Katanas. It appears that they are appreciated for their durability, their hardness and for their affordable price if compared to properties. The easiness of forging reduces dramatically the price of the 11060 swords and makes them very popular.
1060 carbon steel katana is customizable from the forging to the mounting processes. You can chose the Hamon type, the sharpness of the edge, the hardening type and even the forging process. 1060 Carbon steel is hard steel but it is susceptible to hand forging, special press mechanical devices and to milling by dedicated machinery. Opting for 1060 Carbon Steel material is to choose low price material that can be forged into resistant and valuable pieces.
1095 Carbon steel is carbon steel that contains 0.95% of Carbon. Actually, it is called very high carbon steel. This carbon percentage results in hard steel, which is hardly forged by hands. The heat treatment must be conducted delicately because the carbon tends to leak at a certain temperature and if improperly heat treated.
?Heat treatment is to be operated very carefully because it is a delicate operation: improper treatment can result in loss of the carbon fraction and therefore the non-obtaining of the martensite, which can result in the loss of the whole material. The 1095 Carbon Steel comes to be softer than the Stainless Steel, yet it is easier to handle, durable, and more resistant. But among the Carbon Steels, 1095 is the hardest and perhaps the best choice for making swords intended to last longer while being roughly and frequently used.
The Carbon element makes the obtained steel relatively resistant to oxidation even if it has no chromium to be considered stainless. Although, the acquired durability which excels the durability of the Stainless Steel, makes Carbon Steel more preferred for making Swords.
1095 carbon steel katana inherits the hardness and the toughness of the Carbon Steel material. The Swords are intended to regular use and very frequent Dojo cuts. For outdoor displays and shows, 1095 Carbon Steel katanas are more suitable than the 1060 and 1045 Carbon steel Katanas; the last one is already preferred when it is about decorative use. The hardness of the Steel makes the forging process into sword a tough operation and increases the price value of the resulting piece, if handmade. This characteristic induces excellent durability for the 1095 Carbon steel Swords. The durability and the Edge Sharpness are reinforced by the Differential hardening process. It is important to notice that Clay tempered 1095 carbon steel katana are resistant to corrosion and are more resistant to oxidation; they are perhaps stainless. These swords are easier to sharpen and they do not need to have a thick layer of what the swordsmen call 'meat'; the edge keep its sharpness for long time.
The hardness of the 1095 Carbon Steel katana is inherited from the Steel material used for the forgery. Actually, forging Katanas fusing 1095 Carbon Steel appears to be harder than forging swords from others Carbon Steel types. Thus, the price of a 1095 Carbon Steel Katana tends to be higher.
Although 1095 Katanas are tougher than the others Carbon steel Swords they are still susceptible to abrasion and to corrosion if they are not properly cleaned and carefully maintained. Thus, applying cleaning process and using the recommended oil and tools to proceed may augments the durability of the edges and keep the 1095 Carbon Steel katanas properties for long time.
The toughness of the blade, which allows it to be the favorite choice for frequent functional use, may require particular pieces to mount on the blade to form the final Katana. Already, the Carbon steel type has imposed the forging process.
1095 Carbon Steel Katana are full tang katanas because of the hardness of the material and its resistance to shocks which require a tough handle mounted on a tang that is solid enough. Differential Clay Tempering results in a hardening the edge and keeping the spine softer, this operation may increase the durability of the edge and enhances the resistance to corrosion, therefore the edge will support the frequent dojo cut and outdoor display.
