S30V comparison

What knives, made by who, heat treated by who?

It was a Benchmade knife, there are two knives I am talking about both were Benchmades. One has chipped doing light things such as opening a DVD case, one has chipped and I never figured out why it did since I never carried it, took it out of the case one day was looking at it and noticed it was chipped, both blades have a funny yellow milky tint of film that comes up on them no matter what I use to clean them with.

Does Benchmade do it its own heat treating?

I would sure guess that BM does their own heat treating in their own ovens, but somebody here on forums probably knows for sure.

I'd sure as he11 send those both back to BM along with a description of how things happened, and be nice early but eventually demand new replacement blades if they don't respond appropriately. They need to get feedback (customer QA/QC) when they do poor work in heat treat... need to thoroughly test those blades to see what happened.

I have wondered if Benchmade does their own heat treat and tempering. I have had personal experience with Benchmade knives in ATS34 and M2 chipping when sharpened to a bevel lower than 25 deg. I had a guy bring a Mini Afck in M2, which I had sharpened for him, at a 20 deg. bevel, back to me this past week complaining about the small chips in the blade.I resharpend it to 25 deg. because I have seen this before on this brand of knife. Don't take me wrong, I'm not criticizing, only stating what I have seen in sharpening Benchmades. I have two myself, and I like them. One of my sons has a Mini Afck in ATS34 and if that knife is sharpened to 20 deg., it will chip badly. Sharpened to 25 deg. it is ok if you use it lightly. I have sharpened some that are D2 and never had one of them to chip. Only the ATS34 and the M2. I haven't had the opportunity to sharpen a S30V one yet.

FWIW, I've never had a chipping problem in my BM's but none of them are S30V so it's really doesn't apply to this thread.

What I do have in S30V is an LCC that I have put through some pretty vigorous use and it has done great, holds an edge a very long time and has not chipped at all.

I have yet to add a Sebenza in S30V, but plan to. I would also think that Chris Reeve would be the person to consult in heat treating issues since he was supposed to have worked with Crucible on its development.

I used to have a Sebenza in BG-42 and let it out of my hands(stupid me). How does the new steel compare to the old in edge holding, sharpening and corrosion resistance, also how does in compare to 440V in the same areas?

Dear Roy,

If I'm not mistaken 440V is the same as S60V, not the same as S30V. I think that S30V is less prone to chipping and somewhat tougher. 440V or S60V has been around for some time and is deemed a fine steel too. In order to judge a steel, I think one should look a multiple brands and never judge based on one single knife, that's where the forums come in handy
I own a Microtech LCC in S90V, didn't come "super-razorsharp" but cuts anything I want it to easily without damage to the edge... I think that the thickness of the edge also is very important for chipping or so. S90V would be more susceptible to chipping but me, I cannot complain ( I have to admit that I just cannot use a knife that costly for anything, light/moderate use only).
