Does it have issues with the safety lock...on two of my three Strata's yes. But once I figured it out, it hasn't been a problem.
I carry mine fairly often, and I've used it hard at times. I've never encountered the issues other members have mentioned. The Strata has the best Phillips driver on any Gerber BTW.
It probably is. Like I've said, I've used that Strata hard at times, in both a retail and warehouse environment. It's never failed me.
