I got my skates sharpened at Maki's yesterday and had a brief talk with him about skate sharpening.
I don't know why this surprised me. They sharpen skates going by millimeters as opposed to inches. I asked for a 12mm sharpen and he advised that it might be to sharp. If I don't like this 12mm sharpen, I'll go with the 14.25mm sharpen (that's the 9/16).
I've gone to the shop at Nagoya Sports Center and I've always asked for the FBV 100/50 sharpen but it isn't anywhere close to what I remember them being.
Am I the only one in Japan that's lost about this? He does traditional sharpening instead of the flat bottom. which do you prefer?
