I posted a thread about this in general but I'd like a little advice from you guys too. This h1 rolled on me. Can this blade be brought back? It cuts like crap now.

Haha, surprised with the sharpening threads recently that no one's chimed in here. Honestly, I'm very amateurish with my Sharpmaker, so I'd have no clue where to begin with that roll.

I DO know that you can send a SE knife to the Spyderco peeps in Golden to have them re-grind the serrations. It does have a fee attached, but you'd get factory-like work.
 
Alright. I'll prolly send it in. I'm surprised of the minimal amount of replies. It's not my fault this knife crapped on me.
 
I'd say yours is easily fixable, with the right tools.

For damaged serrated edges, like yours, I strongly recommend a coarse DMT serrated knife sharpener, like this:

The conical diamond rod fits perfectly inside the large and small scallops. They come in coarse, fine and extra fine. If you already have a Sharpmaker, I'd say the DMT coarse is the one to go for, since the SM stones are on the fine side and do not remove material quickly. This DMT works even better and faster than the SM diamond stones in my experience.

Once you have removed the damage, refine the very edge on the corners SM brown and white stones.

What is shown appears to be abuse. I've got a number of spyderedge blades in the kitchen and none of the family's abuse has resulted in an edge that poor.

If you have a Sharpmaker, the instructions tell you how to do serrated edges. For every three strokes on the sharpened side, do one on the flatter side to take off the burr. Use the edges of the stones. Start with the diamond rods if you have one.
 
It may be considered abuse, but H1 is a ridiculously soft steel so I can believe that the OP's frustration is legit. Either way, the best deal is to send it to Golden. They'll regrind the serrations if they can't fix it by sharpening. Costs more, but worth it.

I heard that H1 is around AUS-8's hardness. Is it softer?
 
H1 in PE is significantly weaker than the Serrated versions, but H1 is still a much softer steel than most of what Spyderco puts out. That being said, edge roll (or, in this case, serration role) is the primary complaint I've heard and read against H1. This thread offers some interesting insight into steel comparisons.
 
That's not just a rolled edge, one of the teeth on the serrations is half gone.
 
Hey Sosa, my best advice for sharpening serrations is to do regular maintenance with the corners of the sharpmaker rods. If you do a quick 30 second touchup a couple of times a week you can keep your serrations razor sharp without having to do any heavy resharpening work.

Looks like you've been working that thing pretty hard! :). That's cool, that's what the salt line is for imo. Keep in mind that h1 is a very tough steel so the work you are doing to create that level of damage would probably have done worse to most other steels. There is only so much force the tips of those teeth can sustain in any steel.

Anyway, if it were mine I would probably send it to Spyderco to have it resharpened then give it more regular maintenance with the sharpmaker to help keep it from getting so far gone. It's also worth noting that that bit of maintenance will keep those serrations razor sharp, allowing you to work with much less force and preventing a lot of the damage you have on that one.

No knife manufacture will resharpen serrated edge blades

That's not true. We sharpen serrated edges regualrly.

Hey Sosa,

If you have a sharpmaker, I would use the corner of the white stones, slowly with a 3-1 ratio as menbtioned. If you don't have a sharpmaker, I would suggest sending it to Spyderco, they'll sharpen it the same way.

I would avoid conical rods.
