Funny story...I just spend 30 minutes cutting up PCB with a rotary tool and hacksaw without gloves or a vice.

When I finished, I went to get my files to remove the burrs, realised that I hadn't yet removed them from their packaging (having recently bought new ones). So I got out my penknife (a blade less than an inch long), cut the first tie and promptly slipped and ended up with a 2" cut on my palm.

I'd like to point out that this doesn't fit the definition of irony. There's nothing unusual, unlikely or funny* about being injured by a knife.

*Well maybe.
