A while back, I bought a Case 5-blade Sowbelly stockman off the 'bay. It came in an attractive 'Display Tin'. The tin had the usual molded insert inside, covered in the nice (and yet cheap feeling) velvety stuff. The knife was 'displayed' in the molded insert with 3 of the 5 blades open. As is generally the case with these types of displays, a couple of the blades were 'opened' to about 45 degrees or so. Both of them happened to share the same backspring. Now, I'm betting anybody who's ever handled a multi-blade slippie before, already knows that partially opening two blades on the same backspring is NOT a good thing. The spring is flexed at both ends, so there's double the strain on it (can you see where this is going?).
One of the two blades was a small clip. It had been 'fitted' into the molded insert in a recess that was actually molded for the small pen blade. Didn't quite fit like it was supposed to (again, see where this is going?). It was somewhat wedged in place.
When I went to remove the knife from the insert (of course, not yet knowing that it was wedged), I placed my index and middle finger on the handle, nicely positioned over the slot for the small clip blade (here it comes). I gave the thing a little extra 'tug', and the knife had just partially freed itself from the molded insert, just enough for the small clip blade to SNAP shut.
Being that tips of the first two fingers of my right hand were PERFECTLY positioned over the slot for the small clip blade, I became immediately aware of some 'mild discomfort'. As I dropped the knife and the tin (while simultaneously unleashing a forceful stream of expletives), I saw at the periphery of my vision, a little fragment of something which I later identified as a flap of my own skin falling to the floor with the knife and tin. I'd managed to slice a flap of skin (roughly 1/4" round) from the tips of my index and middle fingers, just in front of the nail. The one piece hit the floor, the other was still attached to my other finger by just a tiny bit of skin. Both bled like stuck pigs, of course. Ended up with two bandaids on each finger, one wrapped over the tip, the other to hold it in place.
I met a friend at a local steakhouse for dinner that evening. Felt like an idiot trying to cut a steak with the bandaged (and still oozing) fingers of my dominant hand. It's amazing how a couple of relatively minor cuts, in just the right place, can render a fellow almost non-functional.
I've decided I'm not very fond of knife display tins anymore.
