The Byrd Wings BY21 is a non-locking SLIPIT folder with a bolstered stainless steel handle and G-10 scales. The handle features full-length skeletonized liners, screwed together construction and a 4-way pocket clip. The dual hollow-ground blades include a serrated Sheepfoot-style blade and a plain-edged drop-point blade for intricate and precise cutting. Each blade is made from 8Cr13MoV stainless steel, with the two sitting shoulder-to-shoulder, opening smoothly in opposite directions with the help of phosphor bronze washers. The Byrd Wings are designed to be used one blade open at a time.
While some knives with dual blades can be a bit disappointing, with sloppy action and a gimmicky design, this knife's action is smooth and deliberate and its design is classy and stylish.
