A tree trimmer from Pennsylvania is expected to make a full recovery after an on-the-job accident sent a chainsaw blade into his neck and shoulder. 21-year-old James Valentine was part of a crew pruning trees in Pennsylvania when the saw, which was still running, hit a knot in the tree causing the chainsaw to kick back into his body.

Luckily the chainsaw missed a main artery and most of the damage was to his shoulder. Emergency workers removed the motor of the saw, but left the blade in Valentine's neck and shoulder to prevent additional blood loss. James is expected to make a full recovery, but it will take a few weeks to completely heal. Report by Sarah Kerr.
