Think I'm going to try to return my CP1 (need a printer)...bad blade grind especially at the tip, something that looks like a tiny dead bug on the inside, lock-up is very gritty (requires strong shake when depressing lockbar or slight push from other hand's thumb to move blade from open position), inside of blade tang has surface rust, inside of liner holes looks horrendous, back of blade tang has a nick in it that would need a lot of buffing and engages only right side of stop pin, etc. Worse CS folder I've seen by far out of 16 years handling a bunch and owning quite a few....really one of the worse folders fit and finish wise I've seen regardless of brand or price.
I can see how it will eventually get very smooth as it pops open nicely even with the gritty initial action, but not sure if I feel like trying to clean it up honestly. Handle butt does dig into my thumb joint when I thumb cap it as I suspected it might, so I would have to round that off also.
Definitely seems like a great design for tactical folder but needs slight changes for me and definitely needs to come in better shape...gives me a very strange impression that it was a blemish that was sitting in the back of the warehouse for a couple months and a worker sneaked a few of them out to retailers.
