MT 154CM v/s Spyderco 440V

Rouge is just iron oxide (rust), it is used primarily to polish soft metals like brass. For cutlery you want a compound designed to polish stainless or tool steels. However this still doesn't explain why the strop would impact the edge on the 440V negatively and yet do a decent job on BG-42 or anything else, unless maybe you are pressing really hard and rolling the softer 440V.

Yes, Vanadium Carbides are harder than just about anything except Diamond. There are ceramics that are harder but they are rare (Boron Carbide) and I don't think much in use in the cutlery industry.


I found out about this a while ago when I mentioned to Phil Wilson that I was losing aggression on the CPM-10V blade he made for me. When we discussed sharpening methods he commented that since I was using a hone softer than the Vanadium carbides once they rounded out they never got recut. I switched to using diamonds on occasion and problem solved.

The Gunting is a solid design but is optomised for something that I don't have a lot of interest in. I would prefer a different blade shape. The Military would be close to perfect.

I cut up some dog food with no problems with a couple of knives. It tends to just splinter than be smoothly cut, but no impactions. Maybe your type is really high in bone, its easy to figure this out, just chew some up and see if there are decent sized fragments left in it.

I only have spderco 440V, but I am very pleased with it. It will hold an edge very long but not "forever". Do not make the mistake and think it as a wondersteel. It is also fairly hard to resharpen. IMHO, however, it is worth the effort.

Well, no staple found. The dog food is the dry type and I see no bone in it at all.

Strange that. Pehaps I used the blade on something else?

I cannot remember doing so. Also I have heard that many blades will not hold an edge as well as they aught untill they have been shapened several times. Something to do with the laser cutting of blanks burning out the carbon at the very edge. I am not sure if this is true? Also the edge is a factory edge and as we all know, that does not mean a thing. Perhaps it was a VERY thin edge down to 15 Degrees and not my usual 20? I have not had the chance yet to give it a proper go, until then I remain puzzled and confused.

Well, maybe it's not "rouge". It's Dremel-brand dry metal-polishing compound, and works great for 154CM, ATS-34, ATS-55, M2, D2, and BG42 (all of which I've used it with, along with the S60V which it doesn't work well with).

Not trying to just be contradictory, but if it were just the vanadium carbides weren't getting re-cut, why does the same Spyderco Sharpmaker stones work so great on my Talonite Talon. When I do actually decide to sharpen it, I can get a nice, shaving edge on it pretty quickly, using the procedures I outlined above for finishing it. The Talonite's shaving edge lasts forever in comparison with the S60V. OK, forever is an exaggeration. It only lasted at least twice as long. I couldn't take it any further, because I ran out of the cardboard that I was using, and moving to another piece would have have been pointless.

So, I'm right back to where I started: I prefer 154CM over S60V.
