I one hand all the time but I do think I do it out of laziness and complacency. Its faster no doubt to use one hand here and there. Depending on how rushed I am the one handed use goes up and down. But I can't really ever justify it. I just end up doing it. Especially with the 150. it is just too easy. I think of it as a bad habit. I have bad habits all over the place, and I don't really do much about them.
Should we be teaching people how to use a chainsaw one handed? I think not, I would rather any employee that is working for me take the extra time and keep two hands on the chainsaw. If your working for yourself and your racing the clock... have at it. Reg C can cut however he feels like it because he has cut enough things to make his own decisions and isn't cutting huge checks to workman's comp. It just seems to me one of those easy things as an employer to just eliminate it from the culture and everyone is better off. Like wearing eye pro and hearing pro. Its Just good practice.
Marks article I believe, was prompted by Thomas Amorim's article over on the buzz which talks about actually teaching the one handed cut as if it were a legitimate technique. I would agree with Mark that it doesn't make sense to teach one handing as part of your training.
I personally really like Mark B's blog I find him to be a good writer, and I do think he has contributed a lot to our industry. Don't always agree with him but I get his perspective and I always enjoy reading it. You can't say the blog is bad when it prompts Reg to treat us to a 17 minute video.
That said, there was another of his recent blog posts I thought was a bit funny, he was lamenting being labeled Old School for not adopting SRT by some young climber at the TCIA. He goes on to say The trees in his area were unsuited for it... basically that SRT is just another tool in the toolbox it just doesn't happen to be in his toolbox. But he is not Old School, he's a Treemagineer!
I must admit, I did get a little kick out of that one.
