What do you buy to sharpen the teeth on a knife

If you are talking about serrated edges look no further than the spyderco sharpmaker for sharpening

You can use sandpaper and sharpen the backside too. It'll cut down the tips a bit, but will get them sharp.

1000-1500 grit will do

Spyderco, Lansky, Gatco all make sharpeners for them.
