i think the problem rather emerges from a poorly locking up liner than hard use. the millie's lock can take shedloads of force and abuse, and i know, 'cause i've had like five of em.
agreed on the comp.lock. i got a german knife multi-review laying around here, and they tested the ATR against several other tacticals. and boy, these guys don't mess around, serious and extreme hard abuse. and guess what? > all knives developed play or faield completely.......all but the ATR
, not only did it not fail, it didn't even develop a micro-nano-inch of play.....that's impressive.
i had one ATR SS in the past, and the first time i experienced that compression lock i already knew that that one was never ever going to fail......ever.
