Abstract
Described is a device that is to used in conjunction with a chainsaw to keep the chainsaw kerf from closing, thereby greatly reducing the chance of having the chainsaw bar being pinched and bound. Also included is a limiting feature that keeps the chainsaw kerf spacer from being inserted too deeply into the chainsaw kerf, thereby contacting the chainsaw blades. Additionally, a handle is included to facilitate the extraction of the chainsaw kerf spacer from the chainsaw kerf after completing the cut. The kerf spacer can be installed with one hand and without the aid of tools.
