SP193PBK: C193PBK Squarehead Lightweight
The Squarehead is an unconventional pocket knife design created by custom knifemaker Darriel Caston. It combines a distinctive square-shaped sheepsfoot blade with a rectangular, single-sided handle to yield a compact, low-profile, cutting tool that is small enough to carry anywhere.

In its original form, the Squarehead featured a one-piece handle machined from solid titanium—including its integral back strap and LinerLock-style lock mechanism. Its single-beveled, chisel-ground blade was crafted from CPM S30V stainless steel to provide excellent edge geometry and strength, while allowing the cutting edge to nest safely against the inside of the handle scale.

Released in 2015, the original Squarehead attracted a lot of attention, but its premium, high-tech materials left it priced outside the comfort zone of some customers. To remedy that, Spyderco began working on ways of expressing the same groundbreaking design in a more affordable, user-oriented format. The result of that effort was the Squarehead Lightweight.

The Squarehead Lightweight faithfully maintains all the innovative features and compact functionality of the original version, but in a more budget-friendly format. Its amazingly capable sheepsfoot blade is crafted from American-made CTS BD1 stainless steel. Ground only on the obverse side, its flat chisel grind ensures the PlainEdge cutting edge is safely protected by the handle's back strap when closed. The blade's generously sized Trademark Round Hole proudly declares its Spyderco identity and enables it to be easily opened with either one or two hands, while jimping (textured grooves) on the blade's spine ensures a comfortable thumb purchase for enhanced control during use.

The defining feature of the Squarehead Lightweight is its handle, which features an injection-molded fiberglass-reinforced-nylon (FRN) scale with Spyderco's signature Bi-Directional Texturing pattern for a non-slip grip. Nested within the single-sided scale is a stainless steel liner that provides the foundation for a sturdy LinerLock mechanism to lock the blade securely open when in use. Intended for inside-the-pocket carry, the Squarehead Lightweight does not include a clip; however, the FRN scale does have a wide slot at its base that allows easy attachment to a keychain, lanyard, or even a dog tag chain for neck carry.

In many ways reminiscent of the "hideout" knives traditionally carried by spies and covert operatives, the Squarehead Lightweight is also an immensely practical everyday cutting tool that is so lightweight and convenient you can carry it anywhere. In fact, at a scant 1.2 ounces, you won’t even know it’s there until you need it. The Squarehead is one of the most unique cutting tools Spyderco has ever produced.
