Well, I did another Yo to Wa conversion this weekend, this time on a 240mm TKC! For some reason, Kikuichi leaves a groove in the blade just in front of the bolster and grinding it out will make the neck a bit thin, so we left it. Black Maple Burl ferrule, Amboyna Burl handle, based off of a Kono handle length/thickness/height.
Handle before the install. Bolster was peened, so I used the 2 holes to line up the machi. Cleaned it up a little more before the final fitting.
Weight is 177 grams, orig weight was around 204 grams.
