20cv on worksharp wsgss

[KnifeCarsen10]

Hello guys, I would like to know how good of an edge I can get on my Benchmade 551-1 with cpm-20cv using my worksharp wsgss. I don’t have the upgrade kit yet, but eventually I will. With the upgrade kit, I think the diamond grits are 200, 320, 600, and 800. They also have the ceramic rods. After that I will use my strop with green compound.

Because of the Vanadium you can put a nice coarse edge on 20cv but it may take a bit longer. Also you'll want to finish off on diamond bench strops imho.

You may want to consider picking up some aftermarket belts for your WS, specifically the SiC belts as they are able to cut steels with vanadium/high hardness more efficiently than the AlOx belts they normally sell with the WS.

Oh, excuse me for the misunderstanding. I’m talking about the bench stone model with the diamond Hones, not te belt grinder model... thanks for the response!

Thanks! What’s the difference between a nice coarse edge and a nice fine edge?

Simply put, just stopping at a lower grit will make the edge coarser, while refining it more would mean finishing up the upper 2k+ range.

Some steels are better suited to a coarser edge like high Vanadium steels. I believe you can refine the edge of 20CV without too much trouble. Incase you'd rather have a more polished, "smoother" edge.

I see... are diamond stones made in the 2000 grit zone? Also, would a ceramic rod make the edge smoother, finishing with the strop? Thanks

My mistake! I guess I misunderstood the acronym.

That 2k was more of an example than anything. Honestly, I have no idea what the finest diamond stones go up to. You don't need a diamond at higher grits, though. At least I never have. At that point the stone is basically just smoothing out the edge.

As for the ceramic rod, it would take the edge a little further, but isn't exactly necessary. It depends on what type of edge you want. I personally tend finish on ceramics, unless it's something like S30V. I've never actually used a rod, I have always used stones, so I'm sure someone will have a much more definite answer than what I could give you.

Thanks a lot! My 551-1 came from Benchmade with an extremely sharp edge, and I just wanted to know if I could get it to that edge again once I dull it. Granted, this will take some time.

Ahh didn't realize that it was the other work sharp. For ceramic rods I'd avoid them when steels with high Vanadium content. They will load up fast and need to be cleaned up often due to this. Also some have mentioned that it can cause carbide tear out when used on edges with Vanadium on them due to it being less hard than Vanadium.

Another reason to use diamond or cbn for the strops, plus these compounds help give that edge a nice sticky or crisp edge once your off the stones whatever they be.

Alright... thanks so much!
