I just did some touch up with some al ox lapping film I got at best. It has the adhesive backing. I use the 8 k equivalent then the 14k then the .3 micron( don't know the grit equivalent). I have been using the .3 after
My 12k naniwa. It seems to me that you could definitely use it for new or well taken care of razors, but I don't think they would hold up on some eBay specials.(I could be wrong). I touched up 4 razors. It went well. I used a granite tile that I had cut to 3x6. No tearing of the paper. Its definitely cutting as you can see the slurry building up. I'm waiting for some diamond from lee valley. Give that a shot. I'm sure they will shave well as I am already using the .3 micron but I will see tomorrow. HHT same as before. In the long run I think this would be expensive. And there's nothing like a real hone. If you don't have any stones and only have a couple razors to take care of, I'm sure they will serve you well.
