How about a Salt Millie?

I think it would be a great way for Spyderco to lose money. It is not economically feasible to flat grind H-1 on a production line, so you'd either have a saber grind (:barf:) or the blades would have to be custom ground, probably doubling the production cost of the blade. Then you either have to have pinned construction or find totally rust-proof threaded fasteners of sufficient strength to assemble the knife, again increasing the production cost. The easiest way to make the liner lock rust-proof would be to go to titanium and figure out how to overcome the relatively low wear resistence of both titanium and H-1 to give an acceptable service life. I suspect it would end up costing more than a large Sebenza without the ultra-precision machining the Sebbie is famous for, anf folks would be whining about blade play in a year or less.

As much as I would hanker for a H1 Millie (with yellow G-10!) I don't think it will happen. The above reasons should be sufficient.
 
Thanks for the reality check. Pacific Salt it is. Maybe a Krein regrind.
 
Oh, I know it can be done. If Tom Krein can FFG H1, than Spyderco can. I don't think H1 is any harder to grind than VG-10.

H1 work hardens; they start grinding and it gets harder and harder and harder. It is possible to grind, but not economically smart because it eats up abrasives.

Tom Krein charges extra for ZDP-189 because it is harder and eats belts faster. H1 is the same price as VG-10 to FFG.

I bet the same argument was once said about FFG Delecas and Enduras, yet they are now standard for the same price.

Purportedly, heating the blade excessively also relieves the stresses that make it work harden. My guess is they don't keep it very cool while grinding it.

Either way, work hardening is not infinite, I don't think H1 exceeds 61-62, which is still below what ZDP can hit.

The edges of serrations have RC'ed out at 63+...

That explains why my round files are all smooth. :p

Where did you get that information?

It's floating around here somewhere. Check H1 threads, specifically searching for RC numbers.

The great part is I think the spine RC'ed at 52 or something low. The more it was worked (grinding) the harder it was. Bevels were 56-58, edge was 60-61 on PE models, 62-63 SE models.
 
I sure was wrong..

H1 is a precipitation-hardened alloy. And yes, it is also work-hardened. Meaning that anything that you do that causes heat through friction will harden the steel further; it’s also important to note that tests have shown that it does not become brittle. The work-hardened properties of H1 have been proven by analysis independently performed by Crucible Specialty Metals. It is this that explains why an H1 blade with a SpyderEdge has better edge retention than it's PlainEdge counterpart. In the end, the analysis from Crucible found the Rc at the spine was 58, however at the edge it had increased in both the PlainEdge (to 65 Rc) and the SpyderEdge (to 68 Rc).

Why not flat ground? On a production line, flat ground blades are done one side at a time. Grind one side of an H-1 blank to final depth, and the blade will be hardened to the point where it will either eat up abrasives, warp or crack when the other side is ground down. In a custom shop, the craftsman (be it Tom Krein or another) will alternate sides, taking a little off one side, then a little off the other, cooling frequently untill the desired depth is reached. The manual labor involved in doing it that way is many times more than what mass production can tolerate. Go ahead and ask Tom to flat-grind 1200 H-1 blades in a month for you and see what he says. For that matter, the last I heard he was charging $35 per blade to flat grind H-1, which is about half the street price of most H-1 knives.

Hollow grinding is done in one pass, both sides ground at once, so hardening will be even and labor will be minimized.
 
I don't know...

Who said the blade would have to be a full flat grind? There is more to the Military than the full-flat grind.

Don't buy the non-sense about a ti liner -lock wearing too much - haven't heard too many gripe about the plethora of ti linerlocks on the market wearing in excess.

As for ti threaded fasteners, there are lots of those out there too.
