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 pocket knife 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.

Well Designed
John H.
This knife is well designed and very fun just to play with due to its size, but is very functional at the same time! I was pleasantly surprised. Only issue is the edges on the scale are fairly sharp and could cut into your hand if you tried to use it for a bigger task than is intended.
Fun little Tag Knife

I love this for cutting things in the garage. It hangs around my neck and I added a retractable keyback so it reaches wherever I need. Great little cutter, I would want to use it as an EDC due to the size and shape of the grip, but when messing around in the garage it comes in very handy.
