Randomly ordered comments: I agree completely with Ecky H’s comment about dust from grinders, especially when dressing them. I regret the grinder I chose because there is too much runout and I’m pretty sure it is in the shaft, not a replaceable bushing. I have a sanding belt that I use for lathe tools, but it would not be good for hogging off chips: The belts I can get aren’t coarse enough grit and don’t last long enough (I’ve tried a supposedly 36 grit belt). That said, I think knifemakers take a lot of material off with belts, so maybe it is a matter of surface speed? In any case, a belt can throw sparks. That’s not to disagree with someone who says belts are less of a fire risk- I don’t know one way or another, but they can throw sparks. I was taught, if you use a belt sander for metal, never use it for wood. If you go the grinder route, learn how to ring a wheel. I’ve heard positive things about the Work Sharp sharpener, but have never tried or even seen one in person…not sure if it would be appropriate or not.
