Thinning- Whetstone vs diamond

Post by BurlsnBlades »

Soo, I've got a bit of thing and bevel setting to do on both stainless and aogami super. I'm thinking of getting a shapton pro #120, but I don't have any experience with coarse whetstones (currently own imanishi/bester 1200 and 4000). I'm wondering what people have to say about using such a coarse whetstone vs using a diamond plate?

I would say unless you are doing some reprofiling or major repairs stay away from the diamond plates. The scratch patterns are a BITCH to remove.

At a given grit diamond plates scratch deeper but a stone of comparable grit cleans the scratches up well. So a 150 grit stone cleans up a 140 or 150 diamond plate. I also have 46, 60 100 and 150 grit plates too for even faster removal and flattening applications. After a 140 plate use a 150 stone or something close - 220 320 400. Jumping from a 150 plate to a 1k stone usually doesnt work well.

I’m with Jeff on this one. Unless I’m doing a fairly major repair, I try to stay away from diamond plates. I’ve found that my favorite stone for thinning is a Shapton glass 500.

So it sounds like your suggesting I use both; diamond for initial stock removal, and the whetstone for some additional stock removal and to clean up the deep scratches? I like that idea, but I think I'll only be buying one or the other right now, so it sounds like it should be the stone ( or another belt grinder... I've got a 4"). I was feeling unsure about the Shapton cuz I've heard that coarse whetstones wear out fast. But I guess when they're on sale for $26, what the hell, right? Given that at that price they cost about the same as the Norton crysto, which would y'all go with?

If you can get low grit Shapton's for $26 I'd jump on that, you'll get more than your money's worth out of it!

Thanks for the tips. Now, just out of curiosity, what about DMT diamond stones vs Atoma? I'm sure somebody around here's got an opinion ;)

I prefer the Atomas over the dmts. Cktg also has some plates as well which are well reviewed. I also have plates (also well reviewed).

The Atoma plates are the better plates but also more expensive. The CKTG plate is a good budget plate.

"I was feeling unsure about the Shapton cuz I've heard that coarse whetstones wear out fast."

My experience with both the pro and glassstone Shaptons is that they are fast wearing. I used up half of a glass stone on one session on a 120. I much prefer thicker stones for coarse work (i.e 50 mm thick.) The other Shaptons do wear very slowly.

All low grit stones wear fast, but @ $26, WELL worth it.

If you do more than occasional sharpening, thick stones are worth it, especially low grit ones. My cupboard is getting another shelf of stuff lately, all 50mm thick at start. Only exception is my Nubatama platinum 6K stone I got from Ken a year ago. I am doing more and more work on low grit stones. Progression used to be 1K 6/8K and then use. Now I'm doing most of the work on a 220, going to a 1200, 2K, 6K and then strop. I have used cjmeik (Chris) for thinning - he does a fantastic job, knife hot rodder - but I am going to let Ken do my next one - Chris we miss ya bro, but we understand. Ken is my go to for stones and sharpening, he is busy but I have a need for performance increase on a kono GS+ that is just screaming for thinning - profile and steel fantastic for me, just need a bit of performance increase

Get thick stones if you can - I sharpen enough to warrant them, and the only downside is you leave your heirs good stones

Where are you getting a $26 Shapton?

IF you are getting a Shapton get something like a 220 from a reputable dealer (cktg). Take the crystalons off your list. There is a time to be cheap. This isn't one of those times.

@dc2123 I'm not, it turns out. They are on clearance sale at Tosho, but I didn't realize the shipping was gonna be so 'spensive.
