A 'get you out of trouble' solution to nipples pulling off the end of your brake cables while out on a ride. Chrome steel barrel with a chrome steel screw to nip up the cable, cross cut head. For up to 2mm diameter cables (can be drilled out to take a larger diameter if needed). Barrel is 9mm long x 6mm in diameter.
A must have little part to leave in your saddle bag for a rainy day.
