Ive got one its a craftsman, model 146-66995 kind of weak, but good
for kitchen knives and
dosent take much room. It says ( hollow grinder, sharpen & honer ) it
does a good job of
resharpening & honing but not powerfull enough to grind much. I opened
up the 8" black plastic
case and found a sewing machine motor geared way down with a belt. Its
15 years old or more
so it may be out of production, I got it used but new it was less than
40 bucks.
