A double-edged replaceable knife adapted for use with chip-cutting machines of various descriptions. The knife has a pair of spaced deflector portions projecting from the front side of the knife. Between the deflector portions is a channel used in properly locating the knife on a chip-cutting machine. The deflector portions are spaced at equal distances from respective cutting edges in the knife, and provide wear surfaces fronting the movement of chip material thereacross. The deflector portions also control the shape of chips cut by the machine mounting the knife.
