Dang! 65 years? Reg still looks like a spring chicken, those europeans age well. One handle on!To each their own, I'd say. Between Reg and this old coot, there's about 65 years of one handing chainsaws..... though, in my early years, using the rear handled Homelite Super EZ Automatic, and then the Echo 302 and 330, it wasn't done as much.... It's called production..... and I'd wager I can "bar flick" with the best of them.....
