You can look back in time. The night sky is full of billions of stars sitting in the arms of galaxies. The light from those star travels millions of lightyears to Earth so you are effectively looking back in time to observe them. The marbling in the ABS handles of the Back in Time Butterfly Knife is reminiscent of these stars. The handles are silver aluminum with sections of faux black marble composed of ABS creating the effect of galaxies in your hand. The blade is in a clip point style constructed of damascus steel which is durable and won’t rust so the longevity of this knife is assured. The Creature Comforts Butterfly Knife comes equipped with a lock connected to the base of the left handle. Simply close the knife and slide the lock into the right handle and the knife will stay closed.
