It's there a real world difference between a 4-1/2" blade and a 5"?? I'm sure the wise guys, myself included, would say "why yes, it's a half inch!!" I doubt that for any of the tasks the Capt listed anyone would notice it.

The Denmark and the 7-5 #6 grind, in my eyes, are essentially the same knife. I'd build either one. Stainless makes more sense for a fishing knife, but I still prefer carbon.
