well no more EKI's for you then(i'm the knife nazi lol) as they no longer make any framelocks & i dont think they plan on making them again, not in the near future anyway, ya can still find HD's or '12's if ya look and i agree the framelocks are good & imho the '12 is the very best production they make but the liner locks are plenty good too. i saw a post by ernie on the "other " forum when he announced the demise of the HD7 and the '12 & i didnt get the feeling he intends to go into any other framelocks, at least not in the near future, and in his opinion the liner locks work fine. i would also wager the odds of everything in the EKI line becomoing frame locks is right at -0-, nada, it aint happening, zip.
the reason they disco'd the framelocks was they didnt sell well, which is imho the reason most things are disco'd, though all the real "knife nutz" loved the things and were willing to choke up the $$ for them the great majority of folks were not so greatly enamored of them mostly imho due to them being kinda on the high $ side.
but hey i dont really disagree with ya i wouldnt gripe if all of them were framelocks but you must remember also that there is absolutely nothing, nothing at all wrong with a well designed & fitted liner lock.
the reason the claim to be the #1 hard use knives is mostly of marketing but imho they are plenty tough for most anything and have been long before they made framelocks, i have had a lotta folders thru the yrs and other than possibly hinderer, strider or some of the extrema ratio knives (all of which are bigger, thicker and heavier than any of the EKI offerings) i dont know of any which are head and shoulders above EKI in the toughness dept, quite a few are as tough possibly but i dont really know of any BM's or spydies which are that much tougher, possibly a spydie ti ATR, possibly, but they are disco'd too due to the high cost of ti, all the EKI's are ceratinly as tough as any boker or kershaw i know that.
