Unique cuts on the handle and blade give the Kershaw Piston (#1860) a great look. For easy opening, it features SpeedSafe® assisted opening and a convenient flipper. While the Piston is a larger knife, its G-10 handles make it light enough for everyday carry. An Inset Liner Lock secures the blade when open. The Piston offers our quad-carry options and even has a lanyard attachment. Don’t see a hole in the handle? Exactly. There’s a hidden lanyard loop in the interior of the handle so nothing interrupts the Piston’s cool good looks. Made in the USA.
