Great small shop grinder
5/ 5stars

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

Great Product
5/ 5stars

I sharpened 8 sets of planer blades in just a few hours. Easy to use.

I had no trouble setting my new Grizzly knife sharpener up. I learned how to use it on an old blade
5/ 5stars

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!

5/ 5stars

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

Excellent tool.

Great for sharpening planer knives
5/ 5stars

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

Does a good job
5/ 5stars

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.
