Chris Reeve makes what is arguably the best execution of the frame-lock concept, so that his is the one that all other frame-locks are inevitably compared to, but as I understand it the mechanics are not proprietary. It would presumably be bad karma to make a knife that closely resembled a Sebenza without discussing it with Chris Reeve first, but there are many other blade and handle styles out there.
[An aside - At the Blade Show West, I avoided what would have been a polite but professional @$$-chewing by Chris Reeve, by letting him know that I was
not the custom maker with a name similar to mine who, he said, was making a line-for-line copy of the Sebenza, and not to his standards either!]
In factory knives, we have the CRKT S2 and the Benchmade Mono-Lock. The Benchmade has gotting some flack from some fans for having a handle that looks like a Sebenza from a distance, though the blade is clearly not a Chris Reeve. The S2 does not in the least resemble a Sebenza, and the SHOT Show samples I handled of some new smaller S2s answer a couple of complaints I had about the full-size version that they're now discontinuing.
CRKT is introducing a titanium frame lock in the Hammond Mirage series, and Outdoor edge is a little farther from production with steel frame locks designed by Darrel Ralph and Kit Carson.
Chris Reeve makes an excellent frame-lock drop-point hunter, but he doesn't make a Wharncliffe, for example, or a spear-point, etcetera, etcetera.
What about a frame-lock version of a Delica or Calypso Jr. shaped knife? Or a frame-lock version of the C25? It would be nice to have Chris Reeve's input in the design and engineering, since he does frame locks very very well, but it would seem that he has been offered right of first refusal, and has for his own good reasons decided he has other priorities.
A Spyderco-Reeve frame lock would be a very good thing, and I'd be in line to buy them. But, if that isn't possible, a Spyderco-Somebody Else frame lock and/or a Spyderco-Internal Engineering Team frame lock would also be a good thing.
