Thats crazy is that yanagiba on the left meant to be a full size one that he has just used to that extent?
It's from scrubbing the handles daily with powdered cleansers like Ajax or something similar.
Starting this harvest I'm a starving startling artist/
Lyrical arsonist it's arduous spitting this smartest arsenic/
When I was cutting plenty fish.Ahi would get in the handle & would have to scrub it.About 6 yrs ago I got a Stepan Keller culy Koa Buff. horn.It worked great easy to clean.Held up well still have that Aritsugu 270mm blue steel yanagiba.
I don't really want to bump this thread but that pic is way too cool. Excellent stuff.
I just read the other day why the Japanese handle makers use their soft Magnolia wood for the handles and the explanation on one webpage was that "it wears to the user". I guess these handles are actually very comfortable! Maybe not the bottom one but the idea of a knife slowly conforming to the users grip. Never saw proof of this concept before this picture! Awesome!
