I will admit to my stupid mistake... I was too far down a valley (not to mention exhausted!!) to go back for the extendable saw head (fibreglass insulated rods and silky) so I reached up with one hand to cut the high limb, expecting to hold the saw throughout the cut... saw went through the limb, the limb caught the bar, saw dropped with my hand still on the trigger, arm came down on a lower limb, folded at the elbow throwing the tip of the bar into my stomach... No excuses, I know it was a dumb thing to do, I was tired, dehydrated and paid the price.... Please be careful out there, I know you guys will think I'm an idiot but that's ok, I totally deserve it! I will wear this scar of stupidity for the rest of my days........
