Smith & Wesson 24/7 Pivot Lock Knife

The 24/7 from Smith & Wesson uses a pivot lock. A lock is the component that gets worked every single time a knife is opened and closed, so which one a knife uses says more about how it will wear than most of the copy written about it.

Judge a knife by the parts that move. Locks, pivots and detents are what go first on a working knife, and they are also what separate one that still snaps shut cleanly after five years from one that rattles in the hand.
