Mechanical correction of the surface finish of a body. The cutting tool, which extends in a substantially vertical plane P comprises: - a lower cutting part which extends along a plane C which is secant to the plane P, so that the cutting tool 1 has an L-shaped profile, - a lower cutting part which is defined, by an upper face 9 and a lower slip heel soil pressing face and, at its periphery, by at least two lateral faces 11, 12 adjacent to the intermediate part 3 and connected by at least one face defining with the upper face 9 a cutting edge 14 the projection of which onto the plane P forms, with the horizontal, a cutting angle lying between 5 and 25 DEG , and preferably between 10 and 20 DEG . Application to the pruning of vine tendrils. <IMAGE>
