Just picked this up from CraigsList.
Holding the handle with the right hand, there is the advantage of seeing the cut being made and using, if necessary, my stronger arm to control any lurching forward of the blade. Disadvantage is the blade is aimed at my right boob.
Holding the handle with the left hand, I am totally out of the line of fire but can't see much.
Also, if you are to adopt the "straight arm" approach (like when holding a chain saw), wouldn't you need to step back as you bring the saw forward?
I'm looking forward to using it but safety first. I'm waiting on the "upgrade kit" - they said 10 to 12 weeks - must remain patient.
Cheers!
