Makita 9820-2 Sharpener Horizontal Wet Grinder with Rail and Planer Knife jig.
Runs quiet. I've owned this for about 30 years and probably used it three times. It still runs great and the extra jig for holding planer knives is a handy bonus. These are getting very hard to find as of late.
These are well made, sturdy tools and this one weighs in at 24 pounds.
Due to the weight, I will only ship to the lower 48 states.
