Made for severing safety lines under load, “S-Cutter” solves the problem of safety line clips becoming unreleasable in an emergency. With a guarded razor edge, this cutter stows either in the special pocket on a Spinlock DeckVest or in a 2 3/8" x 3 1/2" pouch worn on the life jacket harness. By providing a reliable “means of disconnection,” anyone wearing this cutter satisfies ISAF and Offshore Special Regulations, whatever type of safety line and whatever the type of clip used.
