'Bought this on the last round, non-serrated. Perfect size for pocket, slim profile, and not too heavy.
The assisted opening mechanism on this and most other CRT's is a tension spring, (curved piece of steel) that is pushed back by the opening mechanism. Perhaps counter-intuitively, larger/more heavily weighted blades swing faster and more easily.
With this smaller blade, it can remain partially open on the first try until you are used to opening it. The location of the thumb catch and direction of push are a bit different than others too. Once you play with it a bit, you can easily and consistently open and close it it right or left one handed (although for lefties, the pocket clip, while removable is not reversible). The construction of the casing also allows leverage with a "groove" to hold the base against the heel of your hand with your fingers of the opening hand. Until you get used it, "flick" is all you need to get it fully open with one hand.
I have a number or knives from CRT and others, and carry this very often. The size, profile and lock mechanisms (both of them) are well thought out for a smaller sized knife. It's also easy to disassemble and clean. It holds an edge decently for the steel type and I use mine around fresh and salt water- corrosion has not been an issue (but I clean and sharpen often)
Sassy enough for a good at home redux of Westside story? No. The only knife I'd like to have on a desert island? No. Good knife for daily use? Sure. Worth $25? I'm in for another in case I lose this one, YMMV.
