The ornamental design for a knife, as shown and described.
FIG. 1 is a perspective view of a knife according to our new design;

FIG. 4 is a right, side view thereof;
FIG. 5 is a left, side view thereof;

Within the scope of the appended claim, in which we intend to cover only the ornamental and novel elements shown in the drawings, our invention may be practiced otherwise than as specifically shown and described herein.
