It made a nice scar, though. People can ask her how she got it, and she can say, "oh, that's from a hatchet, a four day journey away from the nearest hospital." My most interesting scar is from the underside of the dashboard on a Honda Civic while installing an aftermarket stereo, and you can barely even see it.
I have never seen a pocketknife injury, though. Nor any from archery equipment, or firearms. I'd probably be most worried about barbed treble-fishhooks and swimming in warm freshwater lakes and rivers. Not really because of drowning, so much as slips and falls from mud or algae-coated rocks, or infectious parasites in the water.
My spouse, on the other hand, never got to do anything fun as a kid, and freaks out about everything even remotely dangerous, like my sharp, pointy tweezers. The only people more unreasonably intolerant of minute risks work for the TSA.
Trampolines, though. Those things are deathtraps. I'd rather have a swimming pool drained of water and refilled with rattlesnakes in my back yard. Also, no [American] football.
"Injury rates attributable to bicycling and use of playground equipment were higher [than trampoline injury rates in comparable age groups]"
Sounds a bit overblown.
