A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp includes a cover rotatably coupled to the spindle, and a detent movable in a radial direction to adjust the blade clamp between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.

A blade holding device for securely holding a saw blade includes a holding unit, a sleeve member, a retaining unit, and a shell. The holding unit includes a clamp member and an insert. The clamp member has two half portions defining a gap for receiving the saw blade, a slot extending through one of the half portions, and an abutment surface. The insert is inserted into the slot, abuts against the abutment surface, and has a threaded hole. The sleeve member surrounds the half portions of the clamp member without blocking the threaded hole. The retaining unit includes a fastening member extending threadedly through the threaded hole for pressing against the saw blade. The shell surrounds the sleeve member and the clamp member.

A reciprocating saw includes a blade assembly having a spindle and a blade clamp. The blade clamp selectively secures a blade to the spindle. The blade clamp includes a cover rotatably coupled to the spindle. The blade clamp is adjustable between a locked configuration and an unlocked configuration. The cover is rotatable between a first rotational position relative to the spindle coinciding with the locked configuration, and a second rotational position relative to the spindle coinciding with the unlocked configuration. The reciprocating saw further includes a barrel surrounding at least a portion of the blade clamp. The barrel includes a plurality of projections extending from the barrel toward the blade clamp. At least one of the projections is engageable with the cover to rotate the cover from the second rotational position to the first rotational position, thereby adjusting the blade clamp from the unlocked configuration toward the locked configuration.
