I am just getting into knife making and bought a $40 HF sander and it has not made it through the first knife. I am 70 years old and live only on SS so I can't afford a lot. I am looking at a Grizzly H7760 right now and was wondering if anyone has tried it. I probably want make but 10 knives a year so the $400-$500 are now in the contest. I would appreciate your help.
