    How big are Japanese water wheels?

    I got asked a question the other day that I could not answer, and I can't find the answer anywhere? What size are the wheels used to grind out the hollow back of traditional kitchen knives?

    Using this as a typical wheel, my guess would be in the area of about 3 foot Dia.

    A couple of knives I have bought seem to have 2 different sizes of shallowness. Meaning 2 different sizes of wheels.

    I thought the hollow back was created during the forging process...like with a hammer.

    I do not regret watching the second video one bit. That was actually pretty freakin' amazing to watch. I like the serious face turned big goofy grin, at the end.

    We're getting a new wheel from Japan soon and I was told that it was over 500 kgs.
