Which design has the magic??
deba deba deba , where are you =)
The grind and geometry on a single bevel is pretty standard. There's a lot more variation when it comes to double bevels.
mhm, but the attainable sharpness is variable. I wouldnt call Masamoto standard in that aspect, especially when 3x pricier knives can "suck masamotos choil" when it comes to that wild crazy edge.
you might try Tanaka Deba, http://www.metalmaster-ww.com/product/44. I have a 180 mm and is a good workhorse.
Whoa! Shigeki Kasumi 210mm deba for 180 bucks!!!!! Holy!
