I have a 350, had it since they were introduced. It's small, lightweight, and the lock is very good on mine. It makes a very nice everyday utility knife, and I carry mine at work clipped to my scrubs, where it is hardly noticeable. It is a nice little knife. However, for camping/etc., I prefer my Victorinox Forester (locking blade, saw, etc.) and a custom fixed blade by Allen Folts (or my SRK). For a more hefty knife, I prefer my Benchmade 730 Ares, plain edge w/ axis lock - very nice at the $100 range.
