How could that happen?

Paper broke scissors for once

Amateurs...

Let's see, they didn't do a wedge cut in the preferred direction of fall, they were cutting down into the tree instead of straight across, that created the pinch point that bent the bar and wrecked a decent chainsaw. They definitely either need training or just let somebody else do it before they take out their own kneecaps!

That's it Ned, you're on pick up sticks duty.

But STIHL...
