I wrap handles in silk, leather, nubuck, and deer skin. All of my wrapping materials come from Japanese vendors known for their high quality.

Yes and no. Most of the methods I use are traditional. However, I make handles to endure years of use by dedicated practitioners who train for hours every week. This means that I prioritize function and durability which boils down to using stronger, more modern adhesives. I also pull the wraps tighter than you will see in museum pieces so that they will be far less likely to loosen over time. A Koryu Crafts tsuka will be beautiful, and it is also guaranteed to last.

No. I have in the past, but I’m prioritizing wrapping at the moment. If you need a core, I’ll put you in touch with someone who will do a bang-up job for you. I will, however, reshape a wooden handle core for you at your request.

It depends on what it is. I wrap handles for serious practitioners, and as such I maintain a traditional aesthetic. If you want something done in a particular tradition — say, gyaku menuki for a Yagyu Shinkage-Ryu practitioner — that’s no problem. If you want neon pink tsukaito, no. My handles represent me in the sword community, and in the larger martial arts world. As long as my good reputation isn’t in conflict with your request, I’m happy to do special adjustments.

I can point you in the right direction for fittings. You will have to order them and get them to me. You have two main choices: modern reproductions or antique fittings. I know reputable modern suppliers as well as excellent antique dealers. Often, getting a handle fully outfitted in beautiful antique tosogu (fittings) is not that expensive. If you’re curious, I can put you in touch with the right people.

Ask your teacher. If you’re not training in a particular system, I can make some standard recommendations. However, anyone working with a teacher should always consult that person for specifications that match your style.
