What makes a reciprocating saw good for demolition versus pruning?

Demolition favors higher amperage or voltage, a longer stroke, and a robust blade clamp, which is why corded 12-amp+ saws get the nod from reviewers for tearing out walls and cutting nail-embedded lumber. Pruning rewards lower vibration, lighter weight, and a coarse 6 TPI wood blade; specialist-community threads stress that blade choice matters as much as the saw itself for clean branch cuts.
