The famous swordsman Miyamoto Musashi designed and made several tsubas on this general design.  This tsuba is a modern "raindrop" damascus steel spin on one of those designs.  The steel was forged by Walter specifically for a recently completed set of tsubas from 1050 and 15N20 steel.  2.75" in diameter; .25" thick.  (The tsuba can be salt blue similar to the other tsuba shown here for a small upcharge:  email Walter from the "Contact" section below for details!)
