Received my K390 Para 3 today and it has to be the worst experience I've had with a Spyderco knife. Centering was terrible, action extremely stiff/gritty but the worst thing was the lock stick. In the past I can usually remedy the first 2 issues and sometimes the lock stick as well but this time no such luck. Emailed Spyderco and the same old story. I pay for the knife that's screwed up and now I pay shipping to send it in plus add the 5 bucks that they request and may be 20 more to fix. Just doesn't seem right to me. Oh well enough belly aching. I typically love all things Spyderco but this one just aggravates me. Anyone else having issues?
