Hi Chris
that is basically what i said at the beginning.... that cutting fabric only tells you about the type of edge.... there are many different types of edges... and all have their strong and weak points.. ... it would make sense that the arms were tailored to the targets they were meant to cut...... hollow grind for razors, flat for bowies, convex for choppers....just for example...
-- ofcourse this is not a static rule..... you can have a wide hollow grind and it will make a stong blade..... or really sharpen a convex edge and it will shave paper..
-- what about the sharpening technology...... it says something about that aswell..... you have to have decent abrasives..... or you simply cannot get a fine edge otherwise...
-- look at the top notch polish on Japanese blades..... if they didn't have access to such fine silicate stones.... it would be very hard to replicate this..... because you simply can't pop over to the local hardware and buy graded abrasive papers... it has to be quarried and graded...
