What are the Grits of the Sharpmaker Hones?

[allanm]

I would like to know what the grits of the Sharpmaker medium and fine hone are.

Thanks

Hmm... if I'm not mistaken, the medium ceramic stone is around 600-grit, whereas the fine stone is around 1200-grit.

Of course, I could be wrong here.

Thanks. If the white hone is already 1200 grit I guess I won't buy the DMT X Fine bench stone after all.

Now I'm really curious.

I had thought the "medium" was about 300 grit and the "fine" about 600 grit.

Hopefully our mystery will be resolved soon.

Blues, that is what I thought the grits on the stones were also. I'm not sure, however.

We have not found an effective way to measure the grit. the stone is not put together with measurable particles like most abrasives. We guess the grit to be about 400, 800 & 1200 for the 3 grits. This is a guess based on "feel", although cuting speed is gerally quicker than comparably numbered grits.

Sal,

Thanks. Do you think that a 1200 grit DMT would improve the finish?

 

[Sal Glesser]

Allanm - I have not used or compared the DMT stone to ceramic as far as the finished edge. I would however like to point out that "improvement" depends on the goal. Some materials need a rough edge for efficient cutting (which changes the direction of the word "improvement").

The actual test, you'll have to do yourself. (nothin' wrong with firsthand knowledge, then you get to share?)

BTW DMT recommends using water when sharpening with their stones. I use their coarser stones for many of my sharpening projects and would agree.
