Don't try to learn to grind free hand on knives. the steel is too expensive. Instead, make 'letter openers' for friends and family for Christmas out of mild steel, 1018. You will have to grind an edge on both sides of the blade, like a dagger, so, 100 letter openers will be like 200 knives. there is no heat treating involved (unless you want to use Gunther quench to harden it up a bit). The worst 50-60 go in the scrap bin. The best, give away or sell cheap.
