I agree with Horsewright, as I've always had good luck with Jantz buffer wheels. I've always used the spiral sewn wheels with great results using Brownells Polish-O-Ray greaseless buffing compound 240 grit on one wheel with 500 grit on the second wheel. I've tried a bunch of different buffing compounds through the years but nothing beats Brownells. The local knife maker who taught me how to make knives turned me onto Brownells. I've tried different compounds since then but HANDS DOWN Brownell is the best. I can get a awesome statin finish saving grind lines with no hand sanding. Since it is grease less you have to store in refrigerator and ordering in the summer months can be iffy.
If I want a mirror finish on blades, which I don't, I use Brownells Polish-O-Ray 555 white. I use same spiral sewn wheels but remove the threads on the last inch or so so it's a loose buffer wheel. I use this to polish my handle scales, bolsters etc. Of course I have to say how dangerous buffers are or I'll get total heck. But any power tool can mane or kill you IF you get to the point your not scared of the power tool.
fitzo brings up a good point. I do stack them to 1 1/2".
