A reciprocating saw includes an outer housing defining a longitudinal axis, a casing positioned within the outer housing, an upstream opening between the outer housing and the casing, a downstream opening, and an egress path extending between the upstream opening and the downstream opening. The egress path includes an upstream portion that extends along the longitudinal axis, a downstream portion that extends in a direction transverse to the longitudinal axis, and a redirecting surface positioned between the upstream portion and the downstream portion.
