I love this s... when it gets personal. Beats the crap out of boring technical threads.
But on a serious note. Some of the uninformed comments here regarding hand tool use show just how dangerous they can be. I spent time as a technical rep for Makita and was responsible for training commercial users in the use of hand tools including chainsaws. (was also a timber cutter for a number of years and involved in chainsaw racing) For the uninformed (gotta keep it personal) a top handle chainsaw of low power has a far greater potential for uncontrolled kickback than a saw with a rear handle. The leverage offered and ability to control kickback (and control the chainsaw) when your hands are close together is significantly less than a rear handled saw. (some authorities require specific additional training for their people to use top handle saws).
Some kickback/chainsaw facts- chainsaws operate at high rpm typically 10000 to 13000rpm. With a 7 tooth drive sprocket (3.5 cutting teeth per 7 drive links) at 10000 rpm that will be approximately 35000 potential kickbacks every minute, 35000 teeth every minute going past your private bits. With 325 pitch chain, engine speed at 10000rpm, 7 tooth drive sprocket, one revolution will equal approx. 100mm of chain. so 100mm x 10000 rpm equals 1 000 000 mm per minute or 60 000 000 mm per hour or 60 kph or 16 mps(I think).
Kickback occurs when the chain stops and a force equal to but opposing is then incurred. So in a kickback situation the end of you chainsaw bar is now coming back at you at 16mps. Human reaction time is approximately .2 of a second so your chainsaw has already cut your head/arm etc and is somewhere behind you before you are able to react.
This forum is way to small to cover something as serious as hand tool use so the main thing to remember with all hand tools is they can and will bite you when you least expect it, and the scariest hand tools to use, circular saw and 9" grinder with a cutting disc by far.
