I posted pics of the wrong modelNo, no, no! Look at the speed - 7200 fps! I have a Grizzly G1015, which is very popular with beginning knife makers, and it runs way too fast at 3600 fps. Beaumont KMG knife grinders (expensive, but this is what pros use) will run as low as 900 fps.
That Kalamazoo will eat up knife blades, destroy the temper, and will go through belts like nobody's business.
Just say no. Seriously.
For some dumb sonofabitch, yesElectric grinders are more likely to eat knives and destroy the temper in the blade. I seen that first hand at work. The knife company let the store use the sharpener for free. They made it up in knife sales.
How would a person grind a knife on that?
My Grandfater was a butcher in a small custom meat market. Those knife grinders would make quick work of sharpening a knife, but were hell on blades. The belt grinder was used on cheap throw way boning knives but a tri hone with stones was used on the more expensive knives.Electric grinders are more likely to eat knives and destroy the temper in the blade.

I know you can raise an edge
But how would you do any blade grinding like the machine I posted would do?
The trick to keeping them from ruining the blade is to keep them cool. Reason they make wet operated grinders for sharpening.I've only used my ken onion work sharp sharpener, and it was easy to figure out and use but put some cosmetic scratches on the side of the blade. No big deal but wish it didn't. Made my inexpensive opinel steak knives feel like new again.
I do have some older shun knives with an 11 degree mirror grind that has chips out of the edge, not sure I want to tackle those yet.
A lot of people did say electric grinders will ruin blades and destroy tips. I think that's true even for whet stones if you don't know what you're doing.
