I own and love a Spyderco Delica. Its half flat ground, half serrated. I bought it used this summer. It worked great. I loved it. Today however, it scared the crap out of me. I was going to open the packaging on a new pair of kitchen shears. They were held in the box by VERY tight plastic ties. I opened my knife. I was going to work it under and pry, then cut them out.
Thank God and his angels I was paying attention. The one handed opening FELT right, it just didn't SOUND right. For once, I listened to that little voice that said "STOP AND PAY ATTENTION, DAMNIT"! I did. The blade didn't lock. If I had tried to to pry stubborn plastic ties off with it, I'd have to change my name from FQ13 to Flipper13 or "The Six Fingered Quaker".

Seriously, I came "that close" to losing fingers as the thing is scary sharp, its a stout blade, and I would be putting a lot of force into prying/cutting stubborn plastic. Bad news in anyone's book. Thing is, it worked fine yesterday when I cut down a box. Not a hint of a problem. Today, it just won't lock. I was wondering if anyone else has had this problem with Spyderco, or could offer an opinion on what went wrong. I'll send it back to the factory and have zero doubt that they will fix or replace it.
Still, its one of those moments that wakes you up. One minute you're opening a box, the next, you're minus four fingers due to equipment failure. It it wasn't for the fact that I didn't hear the click and stopped what I was doing, I'd have been posting this from the ER. Scary stuff. SD doesn't just happen on the street. Sometimes its in your own kitchen, and learning to listen to that little voice makes all the difference.
