This kit came with 4 “stones” – actually 4 steel plates.
The extra course is a little smoother than road surface. When I used this to flatten my 8000 grit water stone, I found that my flattening stone has been worn to a point that is no longer flat. When you get these, sharpen a piece of steel or something hard where you are not looking for that pristine mirror finish. I made a blade for a radius plane – thank Mads for this, the blade is now done – and went to work on this. At first there where a few deeper scratches but that has worked itself out and the stones are cutting smooth. These use water and a touch of soap to remove filings. You can use them dry but the filings will actually make the cutting irregular versus using water.
I have used water stones and oil stones before that – most of my life. The reason I took the jump was that the water stones when they dry out crack and break in half. This gets expensive. I have a broken 400 git stone now and DMT says that these should work in a commercial shop with daily use for about 20 years, will sharpen steel, carbide, and even clean up a glass edge – hmmm, diamond stone – probably will.
After flattening my 8000 stone, I started working on chisels. Most of you are well aware of trying to sharpen a chipped blade and the first couple of passes can really mess up a flat stone – gouge it like crazy. These are heavy steel plates and they do not gouge easily – or at least they didn’t for me, I tried.
Because the kit has 4 different grits, the transition to sharpen is fast – be careful with the extra course, it can leave some good scratches that are hard to remove.
I bought these from Sharpening Supplies on line. Everyone else that offered them had a higher price. Even though they said they were in stock, they were backordered for about a week. The web page is http://www.sharpeningsupplies.com/DMT-8-Dia-Sharp-Diamond-Kit-P405C24.aspx
For 4 stones that should outlast most regular sharpening stones several times over and a whole lot of sandpaper – don’t drop them, they’ll break the floor and your foot, the price is pretty reasonable.
