What is a grinder?
The grinders use in knifemaking are different than the bench grinder your dad had with a stone wheel. The grinders used for knifemaking are actually belt sanders. Most belt grinders use 2 X 72 belts that run on wheels. The knife is ground in different ways depending on where on the grinder the steel is ground. A lot of the grinders used by knifemakers are home built. Probably the best setup for a grinder would be a variable speed motor with a flat platen and a wheel so both flat grinds, hollow grinds and convex grinds can all be made on the same machine.
