I bought this 160 deba off of the bay, with pretty much the only info being that it was made by a Yamato. Does the kanji only say Yamato? And does anyone know anything about him?
I could have spoke more clearly. What I should have said is teach myself single bevel sharpening. Which if it's anything like anything else I've ever taught myself involves ruining something. So, better a cheap knife from eBay than something else.
