The first thing you notice about the Piston is its cut good looks. Both blade and handle are dramatically sculpted for a look you won’t see in just anybody’s pocket.

And speaking of pockets, while the Piston is a larger knife, it won’t put too much weight in your pocket. The key is the Piston’s lightweight G-10 handle and Inset Liner Lock. G-10, an epoxy-filled woven glass fiber material, is extremely tough and stable all by itself. So there’s no need to fully line the handle with steel plate to create a durable handle. That lightens the weight, as well as the thickness of the knife, considerably.

Then, to ensure a secure lock up, Kershaw uses our Inset Liner Lock. We inset a smaller steel plate, which functions like a locking liner, in one side of the handle. When the knife is opened, the steel plate moves behind the blade securely locking is open.

The Piston’s blade is Sandvik 14C28N, a high-performance stainless steel that’s tough, corrosion resistant, and hardened to 58-60 on the Rockwell Hardness Scale. 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 attachment in the interior of the handle so nothing interrupts the Piston’s chiseled look.
