Spinlock’s ‘Ten Point’ philosophy for preventing man overboard stresses the importance of wearing a harness lifejacket combination-and using a safety line. S-Cutter solves the problem of safety line clips becoming un-releasable, under load, in an emergency. With a guarded razor edge and stowed either in the special pocket on the Deckvest or in a simple pouch worn on the lifejacket harness, the Spinlock ‘S-Cutter’ is made for severing safety lines under load. By providing a reliable ‘means of disconnection’, anyone wearing the Cutter satisfies ISAF and ORC recommendations, whatever type of safety line and whatever the type of clip used.
