Information from the Spyderco catalog on the web
C193 Squarehead Folder:
"Darriel Caston is an electrical and electronic engineer by trade who has been designing and making custom knives part-time since 1992. His fascination with small folding knives and mechanical gadgets is clearly reflected in his first Spyderco collaboration: the Squarehead™. A compact, elegantly simple pocketknife with a shape that inspired its name, the Squarehead offers cutting performance far beyond its diminutive size and does it with a high-precision, high-tech flair.
The heart of the Squarehead is its uniquely square-shaped sheepfoot blade machined from CPM® S30V® powder metallurgy stainless steel. Its single-sided, flat chisel grind provides excellent edge geometry and strength and allows the PlainEdge™ cutting edge to lie safely against the handle scale. A Trademark Round Hole™ in the blade proudly identifies the Squarehead as a Spyderco product and allows easy one or two-handed opening.
The Squarehead’s unique single-sided handle is machined from a solid piece of titanium. Its one-piece construction includes an integral back strap that also serves as a blade stop and a guard for the edge when the blade is closed. It also houses an integral LinerLock-style mechanism that locks the blade securely in the open position. Amazingly small and lightweight, the Squarehead does not include a pocket clip, but features a wide slot in the handle for easy attachment of a chain, fob, or lanyard. Assembled with screw-together construction to ensure the precise alignment of all parts, the blade, handle, and other key components of the Squarehead feature an attractive matte stonewash finish."
