Recip blade

A reciprocating saw blade comprising:

• a blade body;
• and
• a cutting edge provided along one edge of the blade body and defining a cutting direction, the cutting edge comprising a repeating pattern of cutting teeth with a pitch of at least 12 teeth per inch, wherein each repeating pattern comprises
• a first tooth with respect to the cutting direction, the first tooth comprising
• a first tooth tip defining a first height;
• a first rake face defining a first negative rake angle;
• and
• a first primary clearance surface extending from the first tooth tip and defining a first included angle between the first rake face and the first primary clearance surface;
• a second tooth following the first tooth with respect to the cutting direction, the second tooth comprising
• a second tooth tip defining a second height that is less than the first height;
• a second rake face defining a second rake angle that is greater than the first rake angle;
• and
• a second primary clearance surface extending from the second tooth tip and defining a second included angle between the second rake face and the second primary clearance surface, wherein the second included angle is less than the first included angle;
• and
• a third tooth following the second tooth with respect to the cutting direction, the third tooth comprising
• a third tooth tip defining a third height that is less than the first height;
• a third rake face defining a third rake angle that is greater than the first rake angle;
• and
• a third primary clearance surface extending from the third tooth tip and defining a third included angle between the third rake face and the third primary clearance surface, wherein the third included angle is less than the first included angle.

A reciprocating saw blade comprising:

• a blade body;
• and
• a cutting edge provided along one edge of the blade body and defining a cutting direction, the cutting edge comprising a repeating pattern of cutting teeth with a pitch of at least 12 teeth per inch, wherein each repeating pattern comprises
• an unset first tooth with respect to the cutting direction, the first tooth comprising
• a first tooth tip defining a first height;
• a first rake face defining a first negative rake angle;
• and
• a first primary clearance surface extending from the first tooth tip and defining a first included angle between the first rake face and the first primary clearance surface;
• a second tooth following the first tooth with respect to the cutting direction and set toward a first side of the body, the second tooth comprising a second tooth tip defining a second height that is less than the first height;
• a second rake face defining a second rake angle that is greater than the first rake angle and that is less than or equal to 0°;
• and
• a second primary clearance surface extending from the second tooth tip and defining a second included angle between the second rake face and the second primary clearance surface, wherein the second included angle is less than the first included angle;
• and
• a third tooth following the second tooth with respect to the cutting direction and set toward a second side of the body that is opposite the first side of the body, the third tooth comprising
• a third tooth tip defining a third height that is less than the first height and equal to the second height;
• a third rake face defining a third rake angle that is greater than the first rake angle and equal to the second rake angle, the third rake angle being less than or equal to 0°;
• and
• a third primary clearance surface extending from the third tooth tip and defining a third included angle between the third rake face and the third primary clearance surface, wherein the third included angle is less than the first included angle and equal to the second included angle.
