wear your own personal shank- right around your neck! kidding, but this necklace is meant to make your grandma say "oh, dear". much heavier and about double the size of our jackknife necklace, the switchblade is a real, functioning knife made from solid brass, stainless steel + abalone shell. each knife is unique as the colour of the shell varies. chain length is 32", all hardware is 100% brass. and yes, you can take this one on a plane (not like anyone travels anymore).
