A jigsaw blade (10) has an elongated body with a first and second end, a cutting edge (18) and an opposing back edge. A plurality of teeth (22) is formed on the cutting edge. The first tooth of the plurality of teeth is immediately adjacent the second end (16) of the blade. The first tooth is raker tooth and has a rake face and a clearance face. The rake face and clearance face intersect to form a cutting edge of the first tooth. The second end defines a plunging nose. The second end includes a nose end surface that extends between the cutting edge and the back edge. The nose end surface is on an angle of about 35° with respect to a line defined by tips of the plurality of teeth. The nose end surface intersects the first tooth relief surface to form an angled cutting edge with a leading sharp point. |
