I've heard of it, with great reviews.
'Cat and bearbait have been poking fun at me about me mashing my thumb with a 4# mallet doing a patio last summer. I posted pictures here, so I deserve it!
I started running a chainsaw ~12 years old. Learned from Dad and Grandad, and by doing 100's of cords of pulp and firewood/year in later years.
I got pretty good with a chainsaw...probably call myself a real good novice.
Couple close calls and nothing more....nothing like putting a hammer in my hand....
One incident was a widow-maker right on top of the noggin...my father said good thing it hit you on the head...Otherwise you might have gotten hurt!!
