I was opening a Supersoaker (giant squirtgun) package at a six year old's birthday party (no beer involved). I was trying to cut a zip tie to release the toy from it's packaging. The reason I was the one doing this is because all my friends know that I always have a knife handy, (except days like tomorrow when I'll be in airports all day) so the kid and his mom brought the Supersoaker to me to be liberated.
As to your concerns about the knife closing if used properly, try this. Hold any old folding knife in your right hand. Now position your index finger along the spine of the blade, so as to have better control while working with the tip. On most blades this is a perfectly safe hold, I've used it for many years when I want a little better tip control for fine work. Now try this with a KISS. You'll find that your right thumb rests right on the lock bar. Unfortunately, I didn't realize this until I squeezed the knife for a sure grip and atttempted to use the front portion of my KISS Tanto blade to push cut the zip tie and free the imprisoned Supersoaker. To my surprise (as well as my wife's surprise and the other couple who were staring at my hands while I opened the package) the lock released and the knife folded right up on my exposed middle finger. I was totally shocked as I'd used this same cut many times with my tanto bladed small CS Voyager. The simple act of trying to hold the knife securely exerted enough lateral pressure on the lock to disengage it. I always keep all my knives shaving sharp and so when it cut me, I looked at the finger and knew immediately that it was off to the ER.
To my surprise, the Dr. told me that a couple stiches would not fix my injury as I'd severed 60% of the extensor tendon that runs down the back of my middle finger. After a little micro surgery (two hours) I was treated to six weeks with my dominant hand in a cast to immobilize my finger while the tendon healed. The only positive thing to come out of this is that I now know that I can write almost legibly with my left hand if I have to.
Could I have sued, possibly, but I'm not the litigeous type. But I am a long time knife user and would put myself in the advanced user catagory and I hadn't caught this design "flaw" until it bit me. I wonder how many others out there have been bitten by the KISS?
As an interesting aside, I had originally seen the KISS with one of my customers. I thought it a cool money clip so I bought one a few days later. My incident happened within a couple weeks of purchase, and the first time I'd tried to use it for more than opening mail. A few days after the incident, I was on the phone with that same customer and said," hey, remember that KISS knife you showed me?" and before I could tell him my saga, he said," oh, yeah. I stopped carrying that thing because it closed on me a couple times, luckily I didn't get cut bad".
Try that hold with yours and do a forward push cut and see what happens.
