The Benchmade Balisong Butterfly Knife 32BK Mini- Morpho Black Plain (Used) knife elements with innovative Benchmade features. Balis are all about swinging, sometimes called doing the dance. The 32 Morpho features a patented liner-sprung latch that opens with a squeeze, yet locks open as well. Solid, machined slab construction is built on jeweled ti-liners (skeletonized G-10 handles). Heat-treated kicker pins keep things rockin’ hard and fast, and a practical D2 tool steel blade features a crowned modified spear-point style and black BK1 coating.
