works GREAT 05/11/2019 2:02:17 PM

I bought this a short time ago and had a need for it as soon as I received it. This grinder works great if you take the time to read the directions and make your adjustments when mounting the blade in the blade holder. It isn't water cooled so do light passes to avoid heating the blade causing brown or blue spots which indicate excess heat and loss of temper . I did a set of 3 blades in half and hour and they worked GREAT.

This knife grinder works quite well and saves taking our planer blades to someone for sharpening. Saves us time and money !!

I have not told my wife that I will only use the grinder to sharpen planer blades on occasion. However having sharpened both sets I use it frequently on wood chisels. Very good machine.

Great small shop grinder 10/21/2017 6:29:54 PM

Had one of these for 4.5 years. Preformed great what is it. A surface grinder costs will over $3000 for a reasonable worn one. My first one was damaged beyond when it was knocked off it shelf. Buying a new was an easy choice

I had no trouble setting my new Grizzly knife sharpener up. I learned how to use it on an old blade 10/01/2017 10:45:54 PM

I was very pleased with the results. With a little practice my results will be perfect. Wait until you see how well it sharpens chisels!

I like my grinder nice to be able to sharpen my own planer blades. Just wish there was a finer adjustment for the blade setting

Great for sharpening planer knives 06/02/2017 11:09:52 AM

Bought this a month ago sharpened 3 four blade sets of 20in. Planer knives saved a ton of money.

So far I've only used to sharpen one set of three blades, but seems to work well. I just wish the tool had a better way to micro adjust the grinding angle. It would make adjusting to the blades existing grind angle easier.
