Kershaw
The Kershaw 5150 Lucha is a made-in-USA butterfly knife built for serious flippers who demand responsive, reliable performance. If you're looking for a butterfly knife that actually moves the way you want it to—smooth, predictable, and fast—this is purpose-built for that job. The Lucha combines precise American manufacturing with materials and engineering details that matter when you're breaking in your flipping technique or refining advanced tricks.
The blade is 14C28N stainless steel with a stonewashed finish, a Scandinavian steel formula that delivers excellent corrosion resistance and edge-holding capacity. The design tapers the blade so weight concentrates toward the spine, creating the pendulum balance that makes smooth flipping possible. The handle is full stainless steel with a bead-blasted surface and rounded bevels—geometry that lets the knife roll naturally through your fingers without catching or binding. That smooth roll isn't accidental; Kershaw's engineering team worked with experienced flippers to dial in the weight distribution and handle contours.
Operation hinges on dual KVT ball-bearing pivots that keep action buttery and consistent, even after hundreds of flips. The latch is rounded to avoid snagging during transitions and features a positive stop so it never contacts the blade during operation. The Lucha is full-sized and weighted for serious flippers—light enough to be fast, heavy enough to have presence and control in your hand.

Yes. The Lucha was designed with feedback from experienced flippers, and its tapered blade geometry and rounded handle bevels create the smooth, predictable action that makes learning easier. The dual ball-bearing pivots keep operation consistent, and the balanced weight distribution helps you develop proper technique without fighting the knife.
14C28N stainless steel has excellent corrosion resistance and hardenability—meaning it holds an edge well and resists rust and staining, even with regular handling and sweaty palms. For a knife you'll flip frequently, that durability and low-maintenance finish matter.
No. The latch is rounded to prevent snagging, and it features a positive stop that keeps it from ever contacting the blade during operation. That design detail is one of the reasons the Lucha feels smooth and safe in extended flipping sessions.
Yes, the Kershaw 5150 Lucha is manufactured in the USA.
