Information from the Spyderco catalog on the web


Ask someone what comes to mind when they think of a multi-bladed pocketknife. There's a likely chance the first thing that pops into their head is a traditional small bone-handled pocketknife like their grandfather used to carry. Those original multi-bladed pocket folders were handy for cutting packages or cardboard and floated deep in grandfather's pocket clinking against his keys and loose change.

The new byrd BY20 Wings is a multi-bladed pocketknife and that is where any similarity ends. It's a medium sized folder offering the best of both worlds with two full-sized blades made of 8Cr13MoV stainless steel. The Sheepfoot-shaped blade is hollow-ground with 3- 3/8 inches (86mm) of serrated cutting edge. The Sheepfoot's rounded tip has no point, suiting it well for puncture-free cutting. The second blade is a clip-point shape, also hollow-ground with 3-3/8 inches (86mm) of plain edge cutting surface for intricate and precise cutting. Combined together the blades pack over 6 inches of cutting power in a 5.4 ounce (152g) pocketknife. Each blade locks open independently with its own side-by-side LinerLock that is jimped (textured) along the locking lever for slip resistant lock engagement and disengagement.

G-10 laminate handle stays grippy in the hand and its' pocket clip carries 4-ways: tip-up/tip-down and left- or right-handed. The clip's end is rounded, lessening wear and tear on a pocket. Includes a nylon belt-carry sheath with snap closure.[1]
