Hi Because I am retired my knife making budget has always been low. But because I'm a retired Carpenter I already had the tools I use most often for knife making, a 4 in. angle grinder and a 4x36 bench sander. Making sure the abrasives for you bench sander are for metal they are different than for wood. For the steel I started out using lawn mower blades and large sawmill blades cut out with the angle grinder and a metal cutoff disc.
