Alright, I guess I might as well fess up to my past sins. When I was a freshman in college I worked part time at a grocery store. I had just bought a Gerber Paraframe thinking it was the coolest thing.
Well I got bored near the end of my shift one night and decided to do dumb things with my super cool new knife. I wanted to practice drawing the knife from my pocket and deploying the blade as quickly as possible. So to try and push myself to be faster, I found an empty cardboard box in the backroom, and with nobody around, proceeded to hurl it straight upward, draw and open the knife, then stab the box before it could fall to the ground.
After doing this a few times with some successes and some failures, I attempted again. Except this time, I was in such a rush to not miss the falling box, I neglected to lock the blade open prior to fully gripping the handle. Thus, when I proceeded to thrust the blade into the box, it promptly closed onto my fingers.
Blood immediately started gushing. My head quickly filled with fright. Was I going to get in trouble for screwing around at work? Did I need to go to the hospital and get stitches? Was I going to get fired for having a "weapon" in the workplace?
I rushed to the bathroom and held my hand under the faucet. The blood continued to flow and showed no sign of stopping. Adamant that I could fix the situation, I wrapped my hand in paper towel and hurried over to the nearest first aid station.
Bandaids, a bandage roll, antiseptic, alcohol wipes, and gauze were quickly raided and carried back to the bathroom. Removing the paper towels from my hand revealed an absolute crimson mess. Running my hand under the faucet again, I managed to get the bleeding to slow.
Quickly patting the wound relatively dry, I applied an egregious amount of antiseptic ointment. Two thick gauze pads were placed on top and a bandage roll was wrapped around my hand to keep everything tight.
Quickly wiping blood spatter from the porcelain sink, I tried my best to make the restroom not look like a horror movie scene. I grabbed a mop and bucket and wiped up all of the blood I had left where I had committed my act of stupidity as well as the trail of blood droplets leading to the restroom. Satisfied that I had sufficiently concealed my accident, I clocked out and went home.
Changing my gauze pads a couple times over the next 24 hours, the bleeding retarded enough to require only some liquid bandage. Using this for another 3 days or so, I eventually was able to avoid ever needing any stitches and somehow my scar is barely even noticeable.
I quickly lost interest in carrying a knife and eventually lost the knife itself. In time I eventually got back into carrying and using folding knives, but the lesson I had learned then still persists to this day: treat tools with respect.
