I've been reading a lot about the Hiromoto AS being a very good knife albeit suffering from excessive thickness. To the point where even Dave proposed a package that includes thinning. Now, I'm looking at JCK and the 210 gyuto is reported to be 2.2 mm thick at the heel and the 240 2.4mm. Wouldn't these be considered almost laser thicknesses? Or is it thickness behind the edge that causes the issue?
