I was splitting wood earlier and found this imprint on a log from the pile. It's where I allowed the saw to get stuck in the tree I was cutting down.
I don't mess up often but I remember this for sure. The branch was at a funny angle so I cut it from the wrong side. This meant the branch gripped the saw as it started to move.
Thought I'd be able to move it quick enough.. but obviously not. I think I I had to fell the rest of the tree with the saw stuck up in it.
Luckily the trusty Husqvarna was unharmed.
