Well, here's one of them.
I bought these a couple of months ago off eBay when I decided to get into sharpening - "damaged Japanese chef knives" or somesuch.
I ended up with a couple each of nakiri, gyuto, and deba. Good thing I bought them for practice, as I have NO idea what I'd do with the debas.
Was it a stupid idea? Probably. But hey, such is life. They didn't cost me too much, and it's interesting to me, if nothing else.
Anyway, here's the first one. No doubt the kanji means "tinfoil" or somesuch (it's insanely light), but I thought I'd better shoot it because if I didn't someone would ask
Weight - 118g
