Believe it or not the first knife I ever bought was a Buck 119 and of course I thought it needed sharpened, age 12 or 13, so I studied what Al or Chuck Buck had wrote in the instructions and did it to the best of my ability. It actually turned out ok, I checked it out the other day and I thought I had done a pretty good job, yes I still have the 119.
On another thread about chickens or something I wrote about working at a corrugated paper plant, one of many jobs I had there was the corrugator operator and you had to make your own paper knife. I started with a broken motorized hacksaw blade and we had a 10" stone mounted in a frame and I went to work. That's how I honed, no pun intended, my sharpening skills. I have a Buck sharpening jig from the very early 70's late 60's I used it once and just put it back. I prefer freehand it takes longer, but you can usually fix your mistakes. I have ran into way too many "grinder" sharpened blades and it just makes me cringe. jbMonkey sounds like he is the exception to the rule though.
