    • A reciprocating saw blade for use with a reciprocating saw includes a body defining a longitudinal axis, an attachment portion configured to couple to the reciprocating saw, and a cutting portion formed on the body. The cutting portion includes a plurality of cutting teeth. Each cutting tooth includes a tip, a rake face extending from the tip generally toward the longitudinal axis and defining a gullet, and a relief surface extending from the tip. The blade also includes a plunge point formed on the body for initiating a plunge cut. The plunge point includes a leading tooth and a second tooth. The leading tooth includes a tip and a rake face extending from the tip generally toward the longitudinal axis and defining a leading gullet. The second tooth is positioned in the leading gullet adjacent the leading tooth and is generally smaller than the leading tooth and each cutting tooth.
