I have never seen someone correctly sharpen a blade using this method. This doesnt sharpen but actually offsets your cutting edge. Yes, you are using the right stones, but only focusing on one singular portion of the blade is detrimental to the edge geometry. Swiping motions reaches the full blade as you push and pull, why do you show incorrect techniques to sell a product?
i cant get anything off my charnley to shave good. scratch pattern is insane scratches everywhere. i lapped flat, then with 2000 paper on glass, then chisel, and nothing. do i have to bare down EXTREMELY HARD when chiseling to smooth?
I have the smaller one. It seems to be a rubber block with some abrasive coating. Non-stick and fast working. No idea how long it'll last. I like that it does now leave rubbery residue like rubber based erasers like Sabitoru can do in extensive use.
