Finer CBN/diamond rods for the sharpmaker?

Postby Haunted House » Sat Dec 28, 2019 8:30 pm

With all these new super steels coming out, Is there any chance we’ll see some finer CBN/diamond rods for the sharpmaker?

Maybe something in the 800-1200 grit range, to compliment the current 400 grit stones.

They've been asking for this for awhile. Hopefully Sal will offer them at some point

If they offered a diamond or cbn rod that was between the current ones and the mediums, I'd buy it. That'd be a great finishing grit for those who like coarser edges. Wouldn't mind seeing a diamind bench stone from Spyderco either.

I think we need a coarser stone myself. The diamonds aren't bad, but something that could really hog off metal would be welcome. I wouldn't be against finer ones either, but I think refining the diamond finish a little with the brown rods works well.

I think they're coarse enough, but being limited to the sharpmaker rod dimensions slows things down. The same grit in a benchstone the size of their ceramics would be an ideal companion to a sharpmamer.

I´d buy the finer CBN rods. The "step" between the current ones and the brown "medium" stones is just a bit wide...

Also the discussions here started by Vivi made me try and appreciate coarser finished edges (I don´t use my white rods at all anymore these days). But the edge created just by the CBN rods is a bit TOO coarse for my liking , but it still could be coarser than coming from the browns (though maybe I could compensate a bit with better sharpening skills, don´t know)

You're probably right. I know they do the job, you just have to swipe up and down or go in circles to speed up the process. Just for reprofiling though... Thinning an edge already at the same angles takes very little time. Which is why I'm trying to get better at freehand. I can take a lot more metal off with a bench stone much quicker, then clean it up on the diamond rods.

Much more to learn, have I!

I don't think the issue is so much about grit as much as it is about how narrow the rods are. Compared to a bench stone you just aren't removing as much metal per swipe. I have diamond plates for my Edge Pro that are comparable to the diamond and CBN rods and they are significantly faster because they're about twice as wide.

If I understand Cliff Stamp correctly, can’t you just make fewer passes on a finer stone to achieve that?

I’m not sure if it’s currently even possible, but I’d quite like to see some Sharpmaker type rods or Gauntlet cats eye shaped rods in a bonded diamond or CBN format, like the 800/1200 Venev OCB stones.

I'm actually wanting to see Spyderco at least come up with one really coarse stone for the 204 Sharpmaker system. And I don't care if it's diamond, CBN, or even aluminum oxide.

Now if they want to expand their selection of different types of stones for the 204 Sharpmaker unit I would go along with it and probably buy everyone that they make available. But they at least need to make one stone that can do rapid stock removal for really beat up and dinged up blades.

I'd buy more CBN rods for the sharpmaker in ANY grit, coarser or finer. More options is a good thing, I'd have uses for both. There are steels that really should only be sharpened with cbn/diamond. Ideally I want an extra coarse, a medium, fine, and extra fine CBN. I have this set up for my KME and it works good for a variety of situations. Extra coarse for reprofiling, medium for 'working edges', fine for refined edges, extra fine for very refined edges and most importantly, quick touch ups.

No. A 1,000 grit stone will not leave the same finish as a 400 grit stone no matter how you modify your stroke. Even stones made out of different materials with similar grit ratings leave different edge finishes.

I would like a Diamond stone for the sharpmaker the same as the medium stones grit
as well as a finer one too. If it never arrives I will build one with a block of wood
and cut slots in it at the same angle as the Sharpmaker and use whatever thin Diamond
stones I can find and just shove them into place. It would be ideal for correcting blades
with non matching bevels. And make quick work of very high Vanadium Carbide steels too.
