Grinder stones?

[buzzy]

I see sausage maker is selling stones to put on auger in the housing to sharpen knife or plate. Anybody use these or have thoughts? Wouldn’t fine wet sandpaper on a piece of glass do just as good a job for a fraction of the cost? Just need more elbow grease. Thanks in advance.

ive never sharpened my own, but I would have to wonder if sandpaper would work.

Not to fear, sandpaper will work just fine. Revered Member, Crankybuzzard, did this how-to sometime ago.
