Abstract: The present invention relates to a bush ax sharpening holder that is adapted to receive and support a bush ax while the same is being sharpened. The bush ax sharpening holder includes an elongated main body structure in the form of a U-shaped channel with opposed open ends. Formed about one open end is a pair of elongated parallel slots. The slots are designed to receive the bush ax blade, and the main body structure is designed such that a handle receiving area is defined through a portion of the main body structure. A blade tightener is threaded into the lower portion of the main body structure and is adapted to be screwed into engagement with the bush ax blade so as to press the blade into a binding relationship with the slots. This serves to firmly hold the bush ax in place in order that the cutting edge thereof, which lies outside of the main body structure of the bush ax sharpening holder, can be sharpened.
