Husqvarna Aluminium Felling / Splitting Wedge

A re-groundable wedge with barb surface on one side that prevents the wedge to go back. 

Wedges help the tree fall in the direction of the notch cut by actually lifting the tree in that direction. Used to prevent the tree from pinching the saw, or leaning back on the saw.

This aluminium wedge can also be used for splitting logs.
