CBN vs Daimond SM rods?

Postby mpgtsm » Wed Feb 12, 2020 9:35 am

I have two S30V blades I use every day. Occasionally they need more than just touching up. Which rods are better as an upgrade.

Thanks, and my apology if this is an old subject.

I never had diamond-, but have CBN rods and all I can say is that they work perfectly well.

Here is another thread concerning your question, including a post of Sal on it: viewtopic.php?t=78443#p1219379

Had both. CBN seems to cut "finer" than the diamonds, while both remove metal just as fast, if that makes any sense. I use the CBN exclusively since I like the edge finish more/get the knife to a more consistent sharpness. Can't go wrong with both, but I recommend the CBN based on my experience.

I can't really compare them because my diamond rods are wore down a good bit, but I don't remember them cutting as aggressively as the CBN do so I have to lean a little towards them. Seems like I read on here somewhere that diamond cuts better but CBN doesn't tear off the rods as easily..? I'll tell ya this much, when they say to use a light touch, they mean it. If you ham fist on either of these rods you'll ruin them.

I enjoy my diamond rods. They work deceptively fast, and leave a pretty good finish. You can always polish up the edge with the medium, fine and ultrafine if you want. I usually just leave the diamond finish, but sometimes do hit it on the brown rods depending on how I feel.

Guys, if I buy the standard Sharpmaker set, do I need additional rods to take to get the knife to sharp?
I mean those CBN/diamonds and ultra fine.

Also, is the honing board with compounds needed additional to previous?

I need to get a good sharpener, as I have 30+ folders in different steels and only a diamond/ceramic stone, and can't get any knife even close to factory level.

I wan't to get a normally priced sharpener (WE and Tormek go too high IMO), and maybe this would be the solution.

From my current steels, I have AUS-8, VG-10, LC200N, CTS-XHP, CPM154, N690Co, H1, 440C, 12C27 and Victorinox steel (whatever alloy that is)

Please advise.

Sharpmaker would be perfect for you! Since you already have a diamond stone for reprofiling or removes chips, though the CBN/Diamond rods wouldn't be a bad idea...that way you could maintain the same angle with all the stones instead of free handing with the diamond you already have. Depends on your skill level with your free hand sharpening I suppose! It's a big leap in grit going from diamond to be the brown rods, so it will take some patience but it can be done. I've done it myself plenty of times now from the CBN to the browns.

Depending how much of an edge junky you are, finishing on the standard fine rods should be fine in most cases. You should easily be able to cut through receipt paper, shave arm hair off the white stones if sharpened correctly.

The only sharpening “system” I have is the Sharpmaker. I have a set of cbn rods, but only ever use them to reprofile an edge to 30* included, or fix a battered edge. Then I rely on the brown & white rods for regular maintenance sharpening. Often I only need the white/fine rods. Some folks do well with a light touch with just the brown/mediums, but I like the white. I also made myself a leather strop; the suede side is loaded with green compound and the reverse is just smooth cowhide. I don’t think I’ve achieved “arm hair tree topping” level, I usually stop when I reach easy arm hair shaving with no razor burn. I also like the Spyderco Doublestuff2 stone. Both of mine have come apart, unfortunately I epoxied my first one back together without thinking. I should have stuck two white stones together! They outlast the cbn. I’d really like a doublestuff “3” with white & brown stones in the same shape as the DS2.

I hardly ever use my fine and ultrafine rods anymore. Finish bevel on diamonds, microbevel withe the browns. Pops hair off the arm and slices paper no problem. I prefer the tooth you get from that progression.

All the stones are good to have though. Some steels work great at the high polishes of the fine and ultrafine. It's good to have variety!

That's how I finished off my M390 Para 3 a couple weeks ago. I actually plan on using it all next week at work to see how I like it and how it holds up.

It really works great. Polishing the bevel works really well for some things, but when there is a toothy finish I find the edge grabs and slices much better. Going through paper it is not as smooth and whisper quiet, but I find I like the aggressive nature of the teeth better!
