A little over a month ago, my adult son and I had the idea to build a coal forge and make some knives. We used some old lawnmower blades to try our hand at making our first knives. Made our forge out what ever scrap metal we could scrounge. Joe my son is a plumber. He had a blower fan from a old hot water heater we used for the forge. It all worked pretty good. So here is my first two. It's kind of addictive. We're learning as we go. He's still on his first on. Being retired, I've more time to work on mine, than he does. It's been fun.
