I completely understand why with the Rekats you went with hardened stainless over titanium. Titanium has its place, but you'd be likely to have galling problems with the steel locking pin if the liners on your knives were ti. A similar question was posed some time ago at the BM knife forum in regards to their axis folders (which I'm sure you tire of hearing of) and the galling issue was raised. For the time being, I see ti as being either a great liner lock material or a material for liners where there is a rocker bar or similar mechnism that creates no friction on the ti itself.
Cold Steel lightweight folders are all right in my opinion for the low price you can find on them in some mail order arenas. I think their fixed blades are some of the best in the business. Having (abusingly)tested a full-sized Gunsite folder however, I found it the locking mechanism to be subject to wear and distortion with only light abuse. I saved enough money on my Cold Steel Kukhri that I decided to pick up a Gunsite folder as well just to see what the Voyager series were all about. From three feet away, I threw it into a 6x6 post on my fence twenty-five times and repeated the test with my axis folder (stupid test really, but clearly defining locking strength). The axis was unblemished, whereas the Cold Steel had developed about three millimeters of play in the up and down movement of the blade. I'm not sure what gave way, the pivot pin or the locking bar, locking pivot pin, or everything, but it wasn't worth a damn when I was finished. My theory is that the handle material around the pins actually "stretched," thus loosening tolerances ridiculously. Cold Steel's testing where they locked the Gunsite folder in a vice and supported 130+pounds on the handle may be a testament to its strength, but I know the knife was probably ruined completely afterward. Comparing price points of the two knives, when you can get a Gunsite for around 59-69 dollars, and on this forum I've seen a Carnivore going for around 100-110 dollars, I don't feel this is that much of an apple-to-oranges comparison. The fact remains that for around 30 to 40 dollars more you can get a (IMHO) 60 to 70% stronger, less resistent to wear (in my case abuse) folder. I know that if the axis stood up to the abuse I gave it, the Carnivore would likely be even more capable due to its "beefierness."
