Show your dangerous side with this unique old school mini butterfly knife necklace. The solid brass folding handles have six piercings and a beautiful vintage patina. Measuring 2-1/4" when closed the length increases to a functional 3-1/2" long when the sharp 1-1/2" blade is fully extended. A folding brass toggle on the end of the handle securely locks the blade closed making it safe to wear. The same toggle locks the blade open during use so it will never accidentally close on your fingers.
