Frequently Asked Questions

What steel types are used in red and blue katanas?
This collection spans several steel grades, each suited to different collecting priorities. 1045 carbon steel is the most accessible, offering solid density and a clean finish that pairs well with vivid lacquered saya. 1060 carbon steel provides a finer grain and holds a polish exceptionally well. T10 tool steel, enriched with tungsten, is considered the premium choice among collectors because it supports clay tempering—a traditional process that produces a genuine hamon, the temper line visible along the blade. Damascus folded steel adds surface-layer patterning that makes each blade visually unique. Your choice of steel affects not just appearance but the depth of craftsmanship visible in the finished piece.
What does clay tempering mean on a T10 katana?
Clay tempering is a traditional Japanese heat-treatment technique in which a layer of refractory clay is applied to the blade spine before the hardening process. Because the clay-covered spine cools more slowly than the exposed edge, the two zones develop different hardness levels. This differential cooling causes the blade to curve naturally and produces the hamon—an irregular, wave-like temper line along the edge. On T10 steel, this line is particularly crisp and detailed due to the steel's fine carbide structure. Collectors regard a genuine, clay-tempered hamon as one of the most important markers of authentic Japanese sword craftsmanship, distinguishing it from acid-etched imitations found on lower-grade pieces.
How does a Damascus blade differ from T10 in this collection?
T10 steel is a homogeneous tool steel valued for its consistent hardness and its ability to form a well-defined hamon through clay tempering. Damascus steel in this collection is a folded steel, meaning multiple layers of steel are forge-welded together and then drawn out repeatedly to create a layered internal structure. When the blade is polished and etched, these layers become visible as flowing, contrasting lines across the surface. No two Damascus blades are identical, making each piece inherently one-of-a-kind. In the crimson red variant offered here, the dark red lacquered saya and koi fish tsuba are specifically chosen to complement the organic, organic patterning of the folded blade surface. For collectors, Damascus pieces are primarily acquired for their visual individuality.
How should I store a lacquered saya to prevent damage?
Piano lacquer and crackle-finish lacquer saya require consistent environmental conditions to remain in pristine display condition. Avoid storage in spaces with significant humidity fluctuations—the underlying hardwood can expand and contract, which stresses the lacquer layer and may cause cracking over time. Store the sword horizontally on a proper katana stand in a room-temperature environment with moderate humidity, ideally between 40–60% RH. Keep the blade lightly oiled with a dedicated sword oil such as choji oil before storing inside the saya; this prevents moisture contact with the steel while also conditioning the interior of the scabbard. Avoid direct sunlight exposure, which can fade both the lacquer finish and the ito wrap color over extended periods.
Are red and blue katanas a good choice as a display gift?
Red and blue katanas are among the most visually impactful display pieces in Japanese sword collecting, which makes them genuinely memorable gifts for enthusiasts, decorators, and martial arts practitioners who appreciate Japanese aesthetics. The color combinations—particularly dragon tsuba pieces with matched ito and saya tones—work well as standalone display objects on a wall mount or horizontal stand without requiring additional context. For gift-giving, pieces with full-tang construction and T10 or Damascus blades carry stronger perceived value than entry-level options. A katana with a thematic tsuba—such as a koi fish or lotus design—also carries symbolic meaning that adds a personal dimension to the gift beyond its visual appeal.

This sword is really nice and sharp. its a pretty blue tent to the blade. The only small complaint would be the container that holds the sword. The inside is like wood maybe if they color that black instead of raw material I guess it’s not really a complaint. It’s more of a suggestion honestly there there’s really no complaints really it’s a nice product.😅 I bought it for my brothers birthday! I want one myself!💛

Not like any videos were saying slandering the tk it's not flimsy, doesn't rust easily, is infact very sharp, saya isn't weak wood and overall is just a very decent maybe even entry level katana for only 200$ I will say though it did bend the very tip of the katana when I hit something metal on accident but that aside its very great qualityr

TrueKatana has adequate blades, primarily T10... best bang for your buck; especially for tameshigiri.r
r
When you order your sword, pray that nothing ever goes wrong because the company has ZERO customer service.r
r
I've ordered 11 swords from this company. Despite that, they NEVER tried to make amends for selling me a shinobi sword once that was fucked up beyond repair. When I lodged my reasonable complaint, they acted like I was full of shit.r

Any decent company would spare NO expense in satisfiying a good customer. Not TrueKatana... they know their customer base needs what they have so they punish you for it.

T10 Folded Clay Tempered Katana with Real Hamon in Dark Red Crackle-Finish Saya - Black Ito Full Tang Sword T10 Folded Clay Tempered Katana with Real Hamon in Dark Red Crackle-Finish Saya - Black Ito Full Tang Sword
Mv Elias Kansas, United States

I buy swords from True Katana because they are pretty okay. I practice tameshigiri with them. They hold up fine.r
What DOESN'T hold up fine is this company itself. They once sent me a dinged and pockmarked shinobi. When I sent pictures and pointed out the damage, they were insolent and rude and dismissive. They didn't even try to reconcile with me.r
I recommend performance Katanas from this company; but you better pray they show up okay because this company's customer service is complete and utter garbage.
