This double edged Fighter features a bottom cutting edge of 5 5/8 inches and a sharpened top edge of 4 3/8 inches from the tip. Spine is 1/4 inch filed from the top cut-out to the thumbrest. Blade depth is 1 3/8 inches. The backside scale is removeable using an Allen wrench (included) to access space for survival gear - a compass, firestarters and fishing line/hooks/sinkers are included. Full tang with a very good handle contour. This is not a brand new knife from Gene - the sides of the blade show some wear as does the handle, which has a cut in the rear, but the blade edges are extremely sharp and it is fully useable. Baker sheath with lanyard, wrench and sharpening stone is in great shape.If you are looking for a solid hard use knife at an attractive price this is worth considering.
