they make (or made) SOCOM and SOCOM elites, the small frame lock one is a mini SOCOM elite, the plain mini SOCOM 's were liner locks.
most of them were 154CM too.
but anyway the SOCOMs and elites are a little different, the elite has a little thicker handle, the microbar lock, rubber/skateboard tape on both sides of the handle vs just on one, and possibly a couple of other things io have forgotten now, oh and the mini elite has the frame lock too vs the liner lock, and is a little larger than the min i SOCOM was.
also they are all available auto or manual and the SOCOM had a couple different blades, one was a tanto, the other a drop point,
i used to collect them and have had a few thru the yrs, still have a SOCOM elite with a brend grind blade, an auto elite and a manual mini elite.
the auto elite is imho the very best side opening auto around, its my fav anyway, and the auto SOCOM is also pretty good, but not quite an elite.
great knives too, they used to be a lot more popular than they are now for whatever reason, i stopped collecting them because they came out with so many special this and limited that that it seemed like they were trying to make everything some kinda collector item and in doing so made none special or limited, also the folks who run the customer service were at one time not the best or easiest to deal with, i have recently dealt with them and they seemed a little better in that regard, but i still dont have my knife back yet, at least they werent rude on the phone lol, thats a start, a few yrs back i wanted a cord for one of my socoms that didnt come with one, you know the lanyard cord, probably less than a dollar worth of mini para cord, they wanted like $20 or $25 for it lol, i called to ask why so much and the CS rep just went off on me, told me they didnt make enuff money, long hours, the job sucked, etc i almost felt sorry for the guy, i did find it odd the guy would tell me all this lol, after it was all said and done he sent me the cord for free lol, go figure.
