A blade clamp for removably coupling a saw blade to a spindle of a reciprocating power tool, the blade clamp comprising: an actuator rotatable about the spindle, the actuator including a first cam and a second cam; and a locking member movable relative to the spindle between a locking position and a release position in response to rotation of the actuator, the locking member including a first section defining a first diameter that is constant along a length of the first section, a second section adjacent the first section and defining a second diameter that decreases along a length of the second section, and a third section adjacent the second section and defining a third diameter that is constant along a length of the third section, wherein the third section of the locking member is engageable with the saw blade to couple the saw blade to the spindle when the locking member is in the locking position, wherein the locking member further includes a first end, a second end opposite the first end, and a rounded head at the first end, and a flange adjacent the rounded head, the flange having a non-circular cross-sectional shape, wherein the third section extends from the second end to the second section, wherein the first section extends from the flange to the second section, wherein the second cam is configured to engage the flange to move the locking member from the locking position toward the release position in response to rotation of the actuator in a first direction, wherein the first cam is configured to engage the rounded head to move the locking member from the release position toward the locking position in response to rotation of the actuator in a second direction, and wherein a spring automatically rotates the second cam around the spindle to cause the first cam to move the locking member from the release position toward the locking position. an actuator rotatable about the spindle, the actuator including a first cam and a second cam; and a locking member movable relative to the spindle between a locking position and a release position in response to rotation of the actuator, the locking member including a first section defining a first diameter that is constant along a length of the first section, a second section adjacent the first section and defining a second diameter that decreases along a length of the second section, and a third section adjacent the second section and defining a third diameter that is constant along a length of the third section, a first section defining a first diameter that is constant along a length of the first section, a second section adjacent the first section and defining a second diameter that decreases along a length of the second section, and a third section adjacent the second section and defining a third diameter that is constant along a length of the third section, wherein the third section of the locking member is engageable with the saw blade to couple the saw blade to the spindle when the locking member is in the locking position, wherein the locking member further includes a first end, a second end opposite the first end, and a rounded head at the first end, and a flange adjacent the rounded head, the flange having a non-circular cross-sectional shape, wherein the third section extends from the second end to the second section, wherein the first section extends from the flange to the second section, wherein the second cam is configured to engage the flange to move the locking member from the locking position toward the release position in response to rotation of the actuator in a first direction, wherein the first cam is configured to engage the rounded head to move the locking member from the release position toward the locking position in response to rotation of the actuator in a second direction, and wherein a spring automatically rotates the second cam around the spindle to cause the first cam to move the locking member from the release position toward the locking position.
