Ferrules, of course. Post yours here.
A few of mine, which I used all on the same day last week at work and thought of starting this thread.
Marko Tsourkan gyuto in 52100 wearing domestic cow horn ferrule, nickel and koa.
Konosuke Fujiyama petty/suji in White #2, ebony and marble horn.
Devin Thomas petty, 52100, butterscotch micarta, wenge.
Ok, so the Devin is more of a dirty blonde. Sue me.
