Holy fucking mother of goddess, Eve! Magsatu, I am glad you survived that experience! I once saw a photo of a severed scrotum, courtesy of a certain rotten website - I know what exactly you mean. That's very horrifying to experience!
The more recent scar inducing experience was about a month ago- I got a new oven - grepa brand, flat surface.. I was still used to the old, dying oven that had little bite so I didn't use oven mittens when handling food in the oven. As a mistake, I used my old habits on the new oven.. totally seared my flesh! AU! Well, the food was HOT and as a kneejerk reaction I rose my hand upward.. unfortunately the hot oven ceiling plate was in the way. Has a scar now between thumb and first finger. At least I know my new oven WORKS very well. LOL
The next recent scar inducing experience was when I took my niece and nephew on a brief expedition at the edge of my property to stand on a round cement base that was used as a pavillion to overlook a very breathtaking sight of the fjord. The problem is... no safety ropes or fences when you're hiking up or down. You could easily topple over and get hurt. I live on the footstep of a mountain. Still high

Miss Delectable knows what I'm talking about. Anyway, as I were escorting the kids back down.. lent them my support. I'm very protective of them. As I saw they were on the ground safely, and their backs were to me.. I could say I was fortunate to prevent them being traumatic from witnessing what happened next: I got crucified.
Well, it didn't go all the way through my hand... I was going to just run down although I was wearing the wrong kind of footwear and the path was muddy and slippery.... but I stumbled and lost my balance, so I grabbed... rusted BARBED WIRES. One caught exactly the middle of my palm, and it bled profusely.. hurt like a bastard. I also twisted my ankle to boot, when I realized what was happening.. I let go of the barbed wire, so I continued to fall... and felt a loud crack in my ankle. No, that doesn't mean I got a broken ankle.. only twisted it, so it was sore for a few days. It did hurt like a bastard. I managed to hide all this from the kids.. but they knew something happened. I clenched my fist, and managed a smile.. pretended to not limp.. told them to go into the house, and did first aid kit on myself. Hubby came home, and became my nurse. You know, I'd do it all again just for his bedside manners.

I know, nuts, eh? Later on, I showed the scar on my palm to Miss Delectable during her visit... she had this funny horrified look on. Hehe.. at least I put my first aid training into practice.
I'll skip all the minor scars (mostly from cats clawing and snagging skin on some protruding objects) and get to a couple of older scars - they were a little more horrifying than the cructifying experience. I nearly sliced off my thumb, and almost split the half of my first finger. Like Eve, I can feel a tingle in my thumb now and then - if I hit in a certain spot. I bear a deep scar around the thumb from the inside, so it's hard to notice until I tell people. I didn't go to ER for treatment of both incidents. I were at a school - had auto repair class and woodworking class. I was exaggerating about the finger splitting scar, but it did feel like that. The thumb.. NOT exaggerated. Went 1/4 of the way before I stopped the buzzsaw.
I also have a scar on my head from hitting it on the pool's cement edge from trying a dive, and then doing a flip. When I shaved my head at gallaudet, everyone definitely noticed it! WTF, Liza, there is a large scar there! LOL Made me look like a butch, I imagine. Strangely enough I got asked out more often BY the guys.
The most visible and oldest scar I have is on my knee. I snagged it on a huge screwbolt on the back of a jeep as I jumped at my dad, and he caught me and lifted me... RRIIIPPP. Got me 6 stitches. LOL I was 4 I think.
I'll show y'all these scars if I ever bump into you in person. I promise.

Great conversation fodder, eh?
One thing about these scars... I am CLUMSY!
