The invention suppresses chipping of a cutting edge of a cutting tool while maintaining sharpness of the cutting edge.

[Solution] A coating (20) of a replaceable knife (10) of the cutting tool is formed so that either one of a rake-face coating portion (22) that coats a rake face (14) or a clearance-face coating portion (24) that coats a clearance face (16) becomes thicker than the other. The film thickness of the thicker coating portion (22, 24) is set in a range of 0.5 m to 15.0 m, and a ratio of the film thickness of the thinner coating portion (24, 22) to the film thickness of the thicker coating portion (22, 24) is set in a range of 0.01 to 0.15.

A saw blade includes a cutting portion having consecutive first, second, and third cutting teeth. Each cutting tooth includes a rake surface, a relief surface, and a tip. The first cutting tooth includes a protrusion extending from the relief surface of the first cutting tooth. The cutting portion includes a first gullet positioned between the first cutting tooth and the second cutting tooth and a second gullet sized differently than the first gullet positioned between the second cutting tooth and the third cutting tooth. The cutting portion includes a first pitch extending over the first gullet from the tip of the first cutting tooth to the tip of the second cutting tooth. The cutting portion includes a second pitch different than the first pitch extending over the second gullet from the tip of the second cutting tooth to the tip of the third cutting tooth.

A land preparation tool includes a cutting surface having a blade and a mounting interface opposite the cutting surface. The mounting interface of the land preparation tool is configured to detachably connect to a tool holder having a top surface, an end surface, a mounting surface opposite the end surface, and opposing first and second side surfaces extending between the end surface and the mounting surface. The mounting surface has an apex extending downwardly from the top surface and first and second mounting faces. The first mounting face extends inwardly from the first side surface toward the apex and the second mounting face extends inwardly from the second side surface toward the apex.
