Spyderco | Squarehead
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 share-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.
Care and Maintenance
Care and Maintenance
To keep your Spyderco knife performing at its best, clean the blade with warm soapy water and a soft cloth after use. For tougher grime, gently scrub with a soft toothbrush. If debris accumulates, use compressed air to clear the pivot and hard-to-reach areas. Ensure your knife is completely dry before applying a drop of lubricant to the pivot for smooth operation. Avoid disassembling your knife unless absolutely necessary, and always follow proper reassembly practices. Store your knife in a dry place and avoid prolonged contact with moisture.
