I like Blade more than the others. It has a fair amount of folder content, but also has a lot of ABS-style (forgive me


) bowie features and info. They recently concluded a long-running series investigating the history of Jim and Rezin Bowie's knives, routinely highlight makers of nice bowies, and have coverage of ABS events and info.
Tactical Knives can be testosterone-laden, but also has more info than I'd expect on small utility knives, machetes, and other functional, notblack, nondeanimatory knife stuff. There are also rare gems- I liked Stephen Dick's short article on Kiwi brand kitchen knives a while back.
Knives Illustrated has a good blend of content, but the magazine itself always seems too short, and it's poorly edited- I find the typos and bad grammar irritating.
Knife books are another subject entirely. I wish I had a spare coupla grand to spend building a knife library.
