TechDiamondTools Diamond Polishing Compound Polishing Paste 14,000 Grit 0-1 Microns for Marble Glass Metal Rock Jewelry Resin Silver Chrome Gemstone with High Concentration of Diamond Powder USA Made

This paste (14,000 grit) does wonder to my straight edge razor after the 10,000 grit stone (using flat leather strop). I might still get the 50,000 grit to get a perfect edge, but it's already close to being "as new".

For i phone screen

Yes. It a very good product. Able to remove the scratches easily.

Would recommend

I’ve used several brands of Diamond paste products for my knives, chisels, and plane blades! This product costs less than some, but gives good service for the price! A little dab on your strop, rub it in with your fingers, then go to town honing your blade! I don’t see much difference in the sub-micron grades. Anything from 5-.05 will give you a mirror like surface that will be sharp!
