I got a couple of nasty, small, shallow cuts while assembling shed bits. It's a problem with screwing metal screws into steel framework based on guide holes -- you wind up with a lot of metal shavings and a lot of sharp bits of steel just waiting for errant hands. I hate little cuts in the lines of your hand because you can't really band-aid them, the sweat and grime gets in them, and the skin around them bends constantly... :-(
My resolution for the next week or two: bleed less.
