Much of the byrd Knife Line is being upgraded through a process called C.Q.I. or constant quality improvement. As the line broadens, existing models are receiving upgraded enhancements such as improved ergonomics, four-way pocket clips and high performance full-flat ground blades. The Robin2 Lightweight is refreshed with these new features. Its mid-size makes the Robin2 an easy knife to carry everyday in an office our outdoor environment. Its full-flat ground blade is high-carbon 8Cr13MoV stainless steel with a comet-shaped hole for one hand opening/closing. Jimping (crosshatching) dots the spine, making a textured section where the thumb rests, creating tactile resistance that restrains the folder from sliding and slipping when cutting. The FRN (fiberglass reinforced nylon) handle is molded with Bi-Directional Texturing with a fish-scales pattern. The scales hold the knife steady while cutting even in hands that are wet, slick or gloved. The welcome addition of a four-way clip offers the option of carrying the folder tip-up/tip-down or left-right-handed and a lanyard hole located at the back of the handle accommodates a secondary-retentive thong or cord.
