spyderedge para 2

Does anyone know if we will ever see one or if there might be one in the works?

I don't think so, but only the man himself would know....

I don't think so either. Can always send one to someone to get pimped with serrations. I've been thinking about doing this to a knife recently so I could get one with a reverse combo edge having the serrations on the top half. Don't really have one I want to do that to though.

Seems like the spyderedge is out of style these days except on the rescue models.

And H1! I wouldn't buy another pe H1 knife after seeing the edge holding capabilities of it's serrations!

I've been hearing this about H1 serrations and there is still something I don't get. Why is there a difference in edge retention of a serrated H1 blade and a plain edge H1 blade and not as much difference in other steels? I've heard that edge retention is better on serrated edges but from reading here the difference is massive with H1 steel. Is this what most people think? I don't have any H1 blade knives.

It's b/c of the work hardening. The steel at the edge of the SE is harder than the PE b/c of the extra work put into the blade.

We'll see about that. My Ladybug will slice paper now, but i'll be using it everyday to open boxes just as i would my Para or any other knife. We'll see how long it takes to bring it down so it won't slice paper.

Also i'm still of the belief that, once you sharpen away the factory edge, you lose that work hardened aspect of the edge...but that's just theory. It's not like the entire steel is hardened..it's just the sharpened edge, so if you hone that away with a stone, what's underneath it?

I would love Sal to put this to the test...do a hardness test on a factory edge and then put the same knife through a rigorous Sharpmaker sharpening and then test the hardness again.

sharpening the knife will only further harden it the same way grinding it does, its the same thing only much less metal is coming off at one time. right?

Work hardening is caused by the heat (friction) of the two grinding wheels putting the hollow grind on the H1 blades. Combine that with the very detailed serrated edge (more machining), and you have at least 1/2" of area that was affected by the grinding. You won't be able to sharpen away the incredibly high hardness of the serrated edge, you'd have to get rid of most of the blade until the spine before you saw a change in hardness.

Back to the topic; I'd rather not see a SE Para 2. The serrated edges just weren't selling very well, which sounds like the reason Spyderco dropped some of them. Lack of an unsuccessful SE version might be part of the formula keeping Para 2 costs low. The only serrated Spydies that I am interested in are the H1 models. Increased edge holding over PE H1, plus SE really helps for rope and other stuff you'll find around boats/water. Just makes sense to get SE H1 in my mind.

Ok let me edit that....so you're saying that the hardening goes deep enough into the steel that it would take a LOT of sharpening to lose it? If that's the case then i wonder if there's anything that could be done to a plain edge H1 blade to give it the same qualities? Maybe a regrind process? If the cutting/grinding of serrations stands as a second work hardening, then could i get a saber grind H1 blade and have it FFG'ed and end up with an equally hard edge?

jossta · #12

Interesting question. Never thought of that. Have seen at least one Kreined FFG H1 Spydie though.

I don't know too much about it, but I would assume that the hardening goes deep enough that it would take a VERY very long time to go past it.

Sai has said though that H1 SE has the best edge retention that they've tested.

Evil D · #13

I'm sure part of that edge retention is just the nature of serrations..since there's more edge surface area compared to a plain edge. I'm definitely intrigued with the FFG H1 idea.

jossta · #14

Maybe part of it but didn't Blerv say the scalloped sections of the blade are approaching 68RC? If that's the case, then more cutting surface is def only a part of it.

Would just freehand sharpening of a PE H1 blade be sufficient to cause some work hardening?
