iv sent my vantage pro small into buck knives to get it fixed for the liner lock problem (it wasn't really fixed because i don't think its that abnormal)... I just walked into my room and got it out just to make sure what i am saying is 100% true (will film and show if requested) but the lock engages at about 20-60% (depending on if i open it with flipper or with thumb hole) and by just pulling the blade back with my hand it will bring the liner lock all the way to the other side of the liner (note im not very strong ) This seems to be a problem with the vantage series of knives but honestly for the price i can put up with it... the lock hasn't failed atleast... it is just how the blade tang is cut... Buck still has alittle more to go before before they are a top knife company in the tactical category, although if they still made the buck/strider knives (or ones of that quality) still i would be taking that back, because that showed that they can make a beast of a tactical knife and can do a great job with a liner lock.
