Bah, bad memories, back in college, we had these beeded thingies hanging in our doorways, and some of them were stuck toghether, so i got my trusty leatherman out and was trying to cut them separate, I thought it wouldn't go through but it did, anyway almost choped off the tip of my finger, felt the blade scraping around my bone. It didn't hurt that much it was realy, really, really....really anoying, unpleasant and uncomfortable, plus becvause it was right on the tip (alsocut my nail half way) it was hard to dress properly, but some untiseptic, bandage and medical tape fixed all that.
When I came over to the med center just to check weather I dressed it right or i buggered up, the nurse didn't know, and the doc was busy, now i got kinda "wavy" midle finger.
I learned my lesson well, after you cut yourself badly make sure to wipe the knife clean or it may rust.
