What is a menuki on a katana?

On a katana, the menuki refers to small decorative ornaments or fittings that are traditionally mounted on the handle, specifically on the tsuka (hilt). Menuki are typically paired and placed underneath the tsuka-ito (handle wrapping) on either side of the handle, aligned with the palm of the wielder when gripping the sword.Menuki serve both aesthetic and functional purposes. They add visual appeal to the sword and are often intricately designed, showcasing the craftsmanship of the swordsmith or the artistic skills of the menuki maker. Menuki can be made of various materials, including precious metals like gold or silver, alloys, or other decorative materials.Functionally, menuki also provide some practical benefits. They serve as grip enhancers, improving the handling and maneuverability of the sword. By adding a slight texture or relief to the handle, they provide a tactile element and prevent the sword from slipping in the hand during combat or practice.Menuki come in a wide variety of designs, ranging from simple and abstract shapes to intricate motifs inspired by nature, mythology, historical events, or cultural symbolism. Some common themes for menuki include dragons, flowers, animals, samurai warriors, or clan symbols. The design of the menuki can sometimes reflect the overall theme or aesthetic of the katana and its fittings.Menuki are not exclusive to katanas and can also be found in other Japanese swords like wakizashi or tanto, as well as in other traditional Japanese crafts, such as tea ceremony utensils or lacquerware. They are an important element in the overall visual presentation and personalization of a katana.

How should I store and maintain a red and white katana?

Proper storage preserves both the blade and the lacquered fittings. Mount the katana horizontally on a sword stand (katanakake) with the edge facing upward to prevent the blade's weight from resting on the cutting edge. Keep it in a room with stable humidity between 40–55% — excessive moisture promotes rust on carbon steel, while extremely dry air can crack lacquered wood over time. Every four to six weeks, remove the blade from the saya and apply a thin film of choji oil (clove oil) or refined mineral oil using a soft, lint-free cloth. Wipe away any fingerprints, as skin oils accelerate oxidation on bare steel. For the lacquered saya, a dry microfiber cloth is sufficient; avoid chemical cleaners that can dull or strip the finish. If you display the sword near a window, consider UV-filtering glass or film, since prolonged sunlight can fade red ito wrap and discolor lacquer over several years.

Are these katana good options as collector gifts?

Is a Shirasaya a katana?

Updated Oct 2021

A shirasaya is not a katana, but rather a type of traditional Japanese sword mount or scabbard. It is a wooden scabbard without any ornate fittings or decorations, typically made from plain wood or sometimes lacquered.

The shirasaya is primarily used for storage and protection of the sword blade when it is not in use. It consists of two pieces: the saya (scabbard) and the tsuka (hilt or handle). The blade is fitted into the saya with no tsuba (guard) or other embellishments, resulting in a simple and minimalist aesthetic.

While the shirasaya is not exclusive to katanas, it is commonly associated with them. Katanas are often placed in a shirasaya for long-term storage or to showcase the beauty of the sword's blade itself without distractions from decorative fittings.

It's important to note that when a katana is mounted in a shirasaya, it is not ready for immediate use in combat. The shirasaya is primarily a display or storage mount, and the sword would need to be remounted in a proper katana koshirae (mountings) with the necessary fittings and handle wrap (tsuka-ito) to be functional for wielding.

So, a shirasaya is a type of scabbard associated with Japanese swords like the katana, but it is not a katana itself.
