Skull Carabiner Clip

A lobster clasp in 316L stainless steel with a skull worked into the gate and the tail. Three sizes: 30 x 13 mm at 4 g, 38 x 17 mm at 7 g, 57 x 21 mm at 17 g.

316L is the marine grade
It is the stainless steel used for fittings that live in salt air, which is the same reason it holds up against sweat.

Clips, does not thread
The spring gate opens against a thumb, so keys, a lanyard or a belt loop go on without unthreading a ring.
