A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle. The detent is movable in a radial direction relative to a longitudinal axis of the spindle 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 blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.
