Couple of years back, picked up my(loved from new) Elu flip saw when it was in rip mode. Grabbed it in both arms, hands either side and lifted it! Blade was at about 60mm high, hugged it as you do, as it's quite heavy and my hand hit the green button on the side. I'd left it plugged in and nearly eviscerated myself. I had not a scratch but no idea how I got away with it, it really shook me up that I had actually done that, I'd been using the thing for donkeys years.
The one that always makes my blood run cold was when a carpet fitter hit the streacher with his knee and hit the pointed end of a bradawl between the pad and his kneeI. It went right up to the hilt straight into the centre of the knee. Bloody horrendous!!
Mind you, this bloke had clouted a previous customers yapping dog and knocked it out or possibly killed it and locked it in an airing cupboard whilst he finished the job, then left without saying a word to the owner.
Karma I suppose, and definately a true story.
