Haha, this thread sends me back in time... The first pocket knife I had, given to me by Dear Ol' Dad when I was 7, is a little pearl-handled pen knife. Pa taught me, of course, how to safely handle the knife, and how to act responsibly when using a potentially dangerous tool. But, being a 7-year-old boy, I'm sure everyone can guess what happened.
Out in the back yard, I took that little knife in my little hand, and jabbed it into the trunk of a little apricot tree. The blade closed onto my index finger, and I sustained a decent cut. Fearing my mother's wrath, and wishing to keep myself and my dad out of hot water, I scurried to the bathroom, washed the cut, and applied a band-aid. My loving mother was none the wiser, and everyone was spared any unpleasantry. This was my first cut with a knife, and probably also my first experience taking care of my own injury.
Of course, that was not my last cut -- I'm sure that even now there are many more in my future, and as a practitioner of balisong manipulation I have sustained more cuts than most folks -- and certainly not my worst, but it sticks in my memory, and probably will until I breathe my last.
Blade Girl, that looks like a nasty one! I'm glad to hear that you did not sustain any permanent damage. You're very lucky for that, since there are so many things in our hands & wrists that are easily injured (nerves, tendons, etc.). Hope you heal up quickly!
