Has anyone ever tried the Supra Ceramic Diamond Stones that Gesswein sells? SCD Stones I was thinking about getting some to use in place of abrasive paper or EDM stones when I'm hand sanding my blades. The stones are fairly expensive though, so I don't want to buy them if someone has already discovered that they don’t work well.

Gesswein has Crystolon Stones, which are much cheaper but I'm not sure how long they would last. Crystolon Stones

Gesswein also carries ruby stones (ruby stones) but they cost even more than the SCD stones.

J.D. Smith told me that he gets his stones from the Falcon Tool Company (Falcon Tool), but he didn't specify what kind of stones, and they have a bewildering assortment.

The bottom line is that I like the idea of using stones instead of papers, but I haven't found ones that I really like yet. (I have used diamond stones and EDM stones so far.) Any suggestions on which stones to use would be greatly appreciated. Thanks.

You might call Charlie Weiss in Phoenix, AZ. All he uses are stones to finish his blades.
The only belt grinding he does is the basic rough bevel grind with 40-60 grit. All the rest of the shaping and finishing is with stones. He makes fantastic knives.:eek:

You can find his number in the back of the Knives annuals.
 
The best thing to do, IMHU, is to order the assortment of broken stones from Falcon. They send a five pound bag of damaged but very usable stones for a ridiculously low price. Use them and take notes on which ones you like for which applications. Then reorder only the new stones that you will be using often. BTW, that bag can last a part-time maker a few years!

Thanks John, I'll give that a try.

By the way, I keep meaning to ask you, what the heck are you doing in Korea? When we met at Ashokan you were living in Cambridge, then I think I saw that you were on the left coast. You sure seem to get around. Active duty military?
 
No. I studied Korean literature in Boston. Took a postdoc for a year in CA. Then took a teaching position in Korea. I'm still here and set up with a great shop--though it's about 45 mins. out of town and I can only get there about twice a week.

John,

That's interesting. You must be one of the few people who actually uses their college degree(s). I guess you won't be back at Ashokan anytime soon, kind of a long commute.
 
Thanks. The SCD stones I was looking at are listed as being "1 x 6 x 100mm". I was assuming that they were 1" x 6" at 100mm (.254"), but perhaps that is not a safe assumption.
 
Doh! Thanks Stacey. I screwed up my conversion (obviously)

, I was thinking that 1" = 2.54mm when it should have been 2.54cm. With your correct figures, that's a whole new ball game. Those stones are too small for my purposes, so I'll have to try John's suggestion about getting the stone assortment from Falcon Tool.

I re-checked my calculations using the correct conversion of 1" = 2.54cm. I got 1mm = .0394", 6mm = .236", and 100mm = 3.93". I think we are all in agreement that those stones are too small and thin.
 
My bad.In rounding the figures to whole numbers I dropped the "0" im .04 by accident.Sorry
