Spyderco s30v vs Benchmade s30v

[orthogonal1]

the taiwanese spyderco blades are heat treated in the US.

So Spyderco grinds and heat treats the blades stateside? Then ships the blades overseas?

That doesn't seem to make sense for some reason.

Should note that Spyderco says CPM-S30V while Benchmade says S30V. Benchmade and other companies may actually be using CPM-S30V. If so, most likely the only difference will be edge geometry and hardening, which can vary on any given production run. S30V itself would have too large carbides for use in knives so I'd assume they all use some kind of powder metallurgy S30V.

Here's crucible's specs BTW.

All S30V is made by the CPM process, there is no non-particle metallurgy S30V.

they make the steel here in the states, heat treats them, then sends that to taiwan, they do the grinding finshing etc.

There is the rub.

Why ship heat treated steel blanks to Taiwan to be ground? The equipment wear would appear to be prohibative.

I was under the impression that pre-heat treated blanks were rough ground, then heat treated.

no we ship the HT steel they do everything else man, at least that is what i think i am sure the steel is made here, and i could swear sal said that they HT them in golden, i could be mistaken but that is how i remember it.

I know the steel is U.S. made. Never heard the rest.

I don't think they can do blade grinds and make spyder/pivot holes in hardened S30V in production capacity and make money, too much tool wear.

i could be wrong, it has happened before.

Anyone notice a difference between these 2?

I find my benchmades take a keener edge and keep it longer.

Is it the heat treat or blade geometry?

Example: Spyderco chokwe and benchmade 940. The benchmade wins.

I just joined the forum after i seen this post. Trying to figure out why the blade in my para 2 was so hard. They both hold a edge pretty good. But I believe the paramilitary holds a little better edge. May just be the diff. In heat treating.
I have mostly benchmades but I bought a paramilitary 2 a few months ago. I never had any problem sharpening any of the benchmade s30v’s even the m390 on my nakamura isnt as hard to sharpen as my paramilitary 2 s30v. except a bm volli that i had, it was pretty hard steel.I just wonder if they didn’t mess up and put a s110 blade or something harder in it. I use a couple of diamond stones and a ceramic rod. Its taken me awhile to get the paramilitary 2 sharp again. I know this is a older post. I just wanted to comment on here in case anyone else was having the same issue.
