I just used a diamond paste on a rag and a worn out BLUE scotch brite pad on
a 90 degree air grinder. You could use a cordless drill also. The blade
wouldnt have a tendency to get hot with the cordless drill. Didnt take much
paste just about dime size drop on the blade. Spread thin with your finger
then buff with a tube sock on your hand or with the drill.
You can find the paste on ebay or look on internet under diamond lapping
paste. Dont really need a bunch of different grits of paste. i used just
the medium and they came out like they did.
Hope this helps!!
