PROBLEM TO BE SOLVED: To provide a blade for electrically-driven tool wherein both a function to form an incision along a mark-off line and a function to cut off an inside part of the mark-off line are provided, in an object to be cut, and forming of incision and cutting off can be easily effected. SOLUTION: The blade for electrically-driven tool comprises a fixing part A detachably mounted to an operation part OP of an electrically-driven tool body MB and a blade body B having a blade part ce which is connected to the part A to cut an object to be cut. The body B has at its forward end an upper surface 1 and a bottom surface 2. At least the upper surface 1 has a forward edge 1a extending normal to the direction of the reciprocating motion of the part OP, a pair of side edges 1b, 1b extending in a direction normal to the edge 1a, and a pair of arcuate corner parts 1c, 1c connecting the opposite edges of the forward edge 1a to the forward ends of the edges 1b, 1b respectively and has an approximately T shape. The edge 1a, side edges 1b, 1b and the corner arcuate parts 1c, 1c are connected to the periphery of the underside of the forward end of the body B through a tapered surface T.
