Greetings and Happy 2022~ had the CRKT M16-02KS model, and was quite pleased with the weight, size, and ergos...However, try as I might, I could not get the blade to deploy fully, unless I accompanied the finger flick with a simultaneous hard wrist flick. That said, two excellent flippers that actually do deploy easily and reliably are the HARNDS Maverick (D2) and the Kizer Junge (N690). Both are extremely sharp out-of-box, well centered blade, very solid, robust, and most reliable for EDC use. I'd like to try another CRKT M Series EDC, but obviously a bit leery of QC issues, at least with the M (16, 21) Series. Thank you.
