Hi everyone.
After learning more about the sharpmaker I think I may try

1) stones from Congress tool (not diamonds)

2) what flat diamond plates are good that can be clipped to the spyderco triangles?
 
Hey Tommy! What are you currently sharpening (type of knife/types of steels) and are you using the SharpMaker for maintaining edges, repair/reprofiling super dull or damaged edges, or both? (Notably, are you sharpening any high-vanadium steels?) If you currently have a SM, what rods do you currently have?
 
Why not just buy the diamond rods made by Spyderco for the sharpmaker? Seems like a lot less hassle than trying to clip plates to existing rods.

This. The diamond rods work great. I tried clipping other stones to my sharpmaker stones, and it just didn't work for me. I reprofiled many blades on my diamond rods though, just takes a bit of time.

However I've seen people use the dmt diafold sharpeners with the sharpmaker rods. Might be what you're looking for.
 
I have all the spyderco rods except the boron. I like the diamond but it is fairly course so looking for a finer option.

I use the SM for everything as it’s all I have right now: reprofile, touchup, everything.

I have an assortment of steels. S30v, 154, s110v, buck stainless, henkels kitchen knives, sandvick stainless.
I’m sharpening folders and kitchen knives: 3 to 8 inch blades.
 
Why not just use the diamond rods and then follow up with the Spyderco ceramic stones,I wouldn't bother with the Congress Tools rods if they are anything like their silicon carbide sharpening stones they were at a stupid fast rate and the only good thing about them is that they are cheap.

I was under the impression that the SM brown/medium and white/fine and ultra fine were not going to work on super steels?

The Spyderco stones can be used on PM steels but from what I have found and also others is that if you use the ceramic stones on S110v and other steels that have a lot of alloy's in them is then you end up with a really crappy edge.

With S110v for example it has a lot of vanadium carbides in that steel and vanadium carbides are the hardest of all the carbides and you need diamonds or CBN to properly cut them,I know a few guys that own guided system's and didn't take my advice used silicon carbide and aluminum oxide stones to sharpen their PM2's and needless to say the edge's were shit and ended up asking me what stones to get.

What happen's when you use silicon carbide stones to sharpen steel's like S110v is you end up sharpening around the vanadium carbides and I have also heard some people say you put micro fractures and stress's in the steel or that you also sharpen around the vanadium carbides until they fall out either way it doesn't matter because diamonds or CBN is what I feel works best for me and nothing else comes close.

If you look at different steels and see that they contain vanadium don't assume that the steel will have vanadium carbides in the steel either,I always thought that if a steel has vanadium in it it must have vanadium carbides it as well and that is not always the case,the reason vanadium is added to the steel a lot of the time is because it is the best thing they can add to refine the grain structure of the steel and make the grain finer,but if they don't take the steel up to a high enough temp when they are making the steel then the vanadium carbides don't form.

When it comes to PM steels like S110v and other steels that have vanadium carbides in them and when you can use water stones is for finishing for a higher grit edge,once all of the heavy lifting has been done by the coarse stones then you can use water stones of any kind because from around 3 to 4K and up your not removing a lot of metal,I have found that the Spyderco stones are really good stones but I use them as a finishing stone more then anything and I don't do a lot of pass's with them I have found if you do to many pass's on them depending on the steel they tend to dull the edge.

Can you recommend a couple of veneve diamond stones I could use as bench stones to sharpen folders like the PM2, or benchmade turret. The steel types are s110v, s35vn, s30v.
Thanks for your help
 
I don't think so but if you shoot Konstantin a message at gritomatic I'm sure he would know.
