Well, Gil Hibben, for one. I was twelve, so youse are going to have to be understanding. I was interested in knives from much younger than that, but the Double Shadow dagger was the first knife that I really noticed knives could be more than just practical cutlery. It was also the first knife I tried to draw a passable imitation of.
Greg Lightfoot, later. I had not quite grown out of the tacticool phase of knife-buying, and his customs were waaaaay out of reach to a boy in his mid-teens. But, his collaboration with CRKT was just barely inside what I considered "too expensive" at the time.
Later on, Bob Loveless for writing down how to make 'em. I was a little slow to adopt the internet, so that book was a holy text, to me.
I also read David Boye's book on the subject, and Knife Talk II, by the fella in Wyoming whose name escapes me at present. Willow bow Ranch, and 52100... Ed Fowler! Thankya, Google.
