on Orders Over $99The Emerson model called the "Commander"typifies the very efficient style of blade shape called the re-curve. Re-curve blades use a conventional V grind and a blade shape that resembles an S-curve along the cutting-edge. The first advantage of the re-curve blade is that the blade's cutting edge is longer than the blade itself. If you were to lay a string along the edge, it would be longer than the blade. The longer edge simply means more cutting surface. Secondly, because of the curve, material is drawn along and into the concave portion of the blade (the inward curve), giving great leverage when cutting cord, clothing or webbing.
Thirdly, the convex portion of the blade (the outward curve) called the belly, concentrates the force of cutting or slashing on the front end, creating a cutting curve that cuts remarkably well with a minimum force. Also because of this upswept curve it is delicate enough to skin large game with ease. The re-curve blade is found most notably on the "Commander"and the Emerson "Patriot"designs.
