My boss strimmed my arm the other week, but with a Sthil petrol strimmer and 3mm cord... it just felt like i had been whipped with a ruler, but 20 times in a second... lol. blood everywhere though! lol
By accident... lol, he walked into me when i was on the hand mower, he had to rev it, because its a brand new strimmer and it cut out when idling, thing is, there isnt ANY modulation with the revs either... its either, on. or off. and lets just say, it was on, when he caught my arm!
