Is vibration white finger related to grip?

[Stefan Palokangas]

I been using chainsaws for a very very long time, and i have a loose grip on the saw, i could not work the saw if i gripped it with my thumb or i would even say it would be unsafe to work that way, i let the saw work for me. I'm even using my knees and elbows at times if i cross cut, move the arms a lot but let the saw go its own way. And i done it since the age of 12, and when employed worked beside power lines, meant felling 50 trees daily for a lot of years.. And i never heard of anyone using a real thumb grip, if they did they would have hurt themselves by now. The more you grip the saw and hold on to it the more damage you get, you muscle tense and you get vibration in your body, you must follow the flow of it and work like a musical with your tool.
