Abstract
Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters.
