ooooh i had a good one last year. i was cutting a hedge that belonged to the neighbour of my parents, as a quick favour jobbie and was using his electric hedge cutter as i had left my work one behind. While i was up there the crap thing got a large branch caught in the blades causing it to jamb. Just as i pulled the thing away to free the jamb (with the trigger released so no power going to it...or so i thought) another neighbour i knew distracted me. hedge trimmer gets free, moves across to my left hand, natural reaction is to grasp it, just as the last smidgen of power is enough to move the blades one little bit. Oh goody i now have a hedge trimmer embedded in the top of my fingers! (god i feel sick just thinking about this) I looked at my hand and thought...yep thats a hospital job!
ended up in casualty, where people kept saying oh youre lucky we had a guy who cut his hand in half on a table saw today. (didnt feel lucky)
after it was all sorted off work for two weeks, absolute agony, now let with one finger that has no feelings in it. oh and a few upset people, who decided to tell me how lucky i was as the day before a man had killed his wife when he droped a chainsaw. After a while i got a bit bored of that soi undiplomatically explained how lucky i didnt feel!
its really funny having no feeling in that finger, as i have drilled/screwed into it several times when holding a piece of timber in an awkward position on a job, and not felt it until its hit one of the deeper nerves, boy does that hurt!
morale of the story is i only do jobs with my equipment, there are no quick jobs, and all the protective gear gets worn, and i dont care who i upset by ignoring them while im using a power tool.
As an aside i did a chain saw curse this year and the guy taking it, had a bald head, with a rather large scar on it. He was talking about safety and protective clothing, and talking about the days when it wasnt required. he then pointed to the scar on his head straight down the middle from front to back. Thats where a chain snapped and whipped up over my head he informed us. AHhh another good reason to where all the kit i thought!
