Knife World is awesome. Thanks again Carl for that Knife World collection, I go back to that for information and just some good readin'!
Knife World and Backwoodsman are my two favorite knife magazines (hey, Backwoodsman has some great articles on old knives from time to time, and my friend Dan Schectman writes for Backwoodsman).
I like the magazine, but Blade is more flash than info, although they do have some informative articles on old knives. Knives Illustrated, I just couldn't get into the layout of the magazine, same flash and no substance, but there are a few gem articles now and again.
Self Reliance Illustrated had some good knife articles, but I heard they've gone under.
