Patent ID: 6840416

Claim:
A knife sheath, comprising: a hollow body for receiving a knife blade, said body having proximal and distal end portions, a mouth disposed in said proximal end portion, and a first longitudinal axis spanning the proximal and distal end portions, wherein the hollow body further includes: a substantially non-deformable outer shell, a rigid inner shell, the outer shell enclosing the inner shell, wherein the inner shell defines a space for receiving a knife blade, an inner length and an inner surface, the inner surface having a plurality of snaced apart elastically deformable linear ridges spanning the inner length of the inner shell, the linear ridges being substantially narallel to the first longitudinal axis and having a sufficient adhesive property to grip a blade through static friction, a suspension strap having first and second end portions secured to each other and to the proximal end portion of the body, to form a loop, and a second longitudinal axis, the second longitudinal axis intersecting with the first longitudinal axis to form a first smallest angle, the first smallest angle being less than ninety degrees.
