Yeah, it's one of three in the "smaller" version...if that's the case, the larger bone version must be huge! I'm not opposed to the size of the one I got, for some reason when you see them displayed like that (3 of one size alongside the big brother version) you sort of think it'll be like the size of an average Case knife in size...nnnope. It's about the size of a SOG or Benchmade type knife.
Yes, that S-2 is the titanium framelock and it came in three sizes. They were the best ones CRKT made in my opinion although, they have another discontinued one called the Apache that's pretty similar and just as rugged and, like the S-2 are getting hard to find. I guess the rule of thumb on good blades is, if you can't find one, that's the one we all should have bought a few more of and stuck in the gun safe when we had the chance!!
The one other I wish I'd bought a few more of is the Gerber SLG...fleabay has had a few and they too are hard to come by...unless you want to pay double plus for them from their original price.
