Sorry for the knife topic. I believe you can shave with it if you want, but you better not :))
I bought this knife today. They say it is Tamahagane steel. 4 3/4 in, ~120 mm long. It was not expensive, around $100. (welcome to Moscow :))) ) That's actually what made me think that it is not tamahagane. What do you think?
