In Praise of the Diamond Stone.
A lot is written about the use of stones. I probably have one of every kind (except a true natural waterstone due to their price - one day...) So I have a little experience. But I have had this stone for about 20 years now and the edge it gives is like a mirror and it cuts so damm fast, always perfectly flat. I paid about £50 for it back then and I think its still under £60 now. Worth every penny, very under rated are diamond stones.
There is now a DMT equivilant to a 8000grit waterstone - that would be worth a look at. But I still finish off with a 10,000 grit waterstone for my finest edges.
