The AFCK is probably my most favorite folder EVER. Too bad they've been discontinued for next to ever. I have one left NIB, and can't decide if I'm going to save it or carry it?I've been carrying Benchmade AFCK knives (one in particular, although I own 3) since 1980. It is a real surprize to hear that someone has had this much trouble with a new Benchmade anything....
I have never had a failure of any type with my daily carry knife of 37 years, (or the other 2 I own), and have rarely needed to do any sharpening other than a stropping on a leather backed wheel to bring it back to razor's edge.
Don't settle for less than perfection with Benchmade....PERIOD.
p.s. I do know from experience of 10~12 years ago, that their customer service is second to none...at least back then.
I hope the best for you in getting satisfaction with your knife.
