Oh, I've broke a few trees. Pretty ugly. As a professional timber faller you can be fired for it. In the least you get an ass chewing from the logger or forester, or both. Kind of hard to hide a 200 foot tall broken tree. Bucking chunks.
Back in the days, when firewood was a big deal here, a faller could actually make more money for himself by breaking or splitting logs.
See, we get paid by the cubic meter, but the price is not the same.
When bucking the bottom log, you make a lot of cubic meters in one cut, so the price per is low.
Then on the smaller logs, that are primarily used for flooring, the price is higher.
Top price was for firewood, cut in 9 foot lengths, because back them we bucked till 2½" diameter, so it took a lot of cuts to make a cubic meter.
A fair system.
If you destroyed a log, you'd have to buck it into firewood lengths. Since the cubic meter price for firewood was double the log price, you could in effect double your pay with sloppy work.
I've only known one guy who really utilized that method.
He was manio-depressive and whenever he was manic, he'd bust up logs left and right.
Eventually whatever god is in charge of logging got tired of that shit, and killed him with a widowmaker.
If that widowmaker hadn't got him first, he would have been fired, eventually.
