If I had to choose I would pick a frame-lock over a liner-lock, but I usually avoid both.
I'd much rather have a lock-back or an Axis-lock.
That is one of the best-looking Full Tracks I've seen. I'm always on the lookout for Hinderers in both S35VN (my favorite steel from them) and a lockbar insert. If you ever decide to sell it....There are hybrids, too, i.e. symmetrical scales but frame-integrated lock:
I was recently using a large Civivi liner lock knife to chop ice off off a commercial walk-in freezer door. I was using the BACK of the blade to whack, and unseated the liner lock. Blade closed onto my thumb, and left a nice clean laceration! Ouch!
Of course I learned my lesson on handling the liner locks with more attention, but I now prefer frame-locks, as they are somewhat more robust.
That's like using your gun to open the mail. Right tool for the right job. Maybe if you enjoy non-cutting activities and knives, an SAK would be the right choice. Don't take my word for it though, I'm not quite sane.I learned my lesson, Chronovore, but I really enjoy using my folding knives for "non-cutting" activities-
opening malty beverages, for instance!
