I just figured that I should account for all sorts of uses, including ones that we may not favor so much
All I have are some entry level Henckels and other various cheap knives, including Farberware. I haven't even touched a real Japanese knife yet, so I'm basing all of this design on what I read and see.
Also, yes, overall height at the heel is currently at 60mm, so if I chop some off at the edge, it'll be within the norm and be at 50mm. For some reason I got confused when reading the forums and thought that the range "45mm-55mm" should be knuckle clearance, rather than overall height.
