Grafting cutter

The utility model discloses a grafting cutter. The grafting cutter comprises a cutter bar, a cutter shank and a cutting edge, wherein the cutter shank is connected with one end of the cutter bar; the cutting edge is arranged on the bottom surface of the cutter bar; an arc-shaped concave surface is arranged on one side surface of the cutter bar; the tip of the cutting edge is inclined downwards. The arc-shaped concave surface is arranged on one side surface of the cutter bar, and the tip of the cutting edge is inclined towards, a cut can be naturally inclined inwards as long as an arm vertically applies force downwards relatively while a slot-position cut far from a ladder end is excavated; compared with vertical downward force application, the inclined inward force application is easier to operate, so that the grafting cutter is labor-saving without frequently erecting the ladder to climb up and down, small in labor intensity on the premise that cut quality is ensured, high in production efficiency and ideal
