Abstract: Apparatus for sharpening cutting edges of a blade is disclosed herein which is foldable between an operative position and a storage position that includes a base having pivoted support sections carrying elongated sharpening elements providing opposing surfaces against which one side of the blade to be sharpened may be drawn when the elements are in their operative position. A handle member pivotally attaches at one end to the free end of one of the elements while a pair of spaced projections are incorporated therein for selectively receiving the free end of the other element wherein the elements are in the operative position. The handle member further includes an elbow portion for releasably receiving the end of the last mentioned element when positioned immediately adjacent the first mentioned element when the elements are in the storage position.

Abstract: A knife sharpener having a pair of abrasive rod members whose bottom ends are mounted on carriages that are reciprocally mounted in channels formed in upstanding block members. The channels travel along an axis that is parallel to the downwardly sloping top surface of the block members. The block members are fixedly attached to the top surface of a base and the mouths of their channels face each other and are aligned on parallel offset axes. The rod members therefore intersect each other at a predetermined angle to form a V at their top into which a knife blade is drawn rearwardly along a horizontal plane to sharpen its edges. Each of the carriages has one of its ends fixedly attached to a spring whose opposite end is fixedly held in position. The downward force of the knife blade as it is being sharpened causes the rod members on the respective carriages to travel downwardly toward each other and when the pressure is released the springs will return them to their initial unloaded positions.

Abstract: A unitary pocket sharpener for knives is constructed from first and second overlaid metal discs each having a section with a straight edge, the edges being mutually arranged to form a wedge-shaped gap of approximately 40.degree.. On each straight edge is brazed a rectangular carbide tooth, longitudinally positioned on opposed segments of the straight edges such that the two juxtaposed teeth cross forming a similar wedge-shaped gap with a narrow space between the crossed teeth. The teeth each have a compound-beveled sharpening edge which respectively engage each side of a knife blade that is lodged in the small gap and drawn across the teeth in a uniform stroke for sharpening the knife.

Abstract: A device to sharpen a blade, comprising a hand-grip, a dual, beveled-edge, reversible, blade cutting or honing system, and a finger protector displaceably carried by said hand-grip.

Abstract: This disclosure relates to sharpeners for blades having a cutting edge, and is particularly concerned with knife sharpeners of the type where two sharpening elements (generally known as "steels") are located in a housing in overlapping V-formation and spring-loaded towards each other, with an access opening in the housing to allow the blade of, e.g., a knife or pair of scissors to be pressed against the steels, and when reciprocation of the blade effects sharpening of the cutting edge. Such sharpeners known hitherto, are arranged to provide a constant V-angle between the sharpening elements, and accordingly produce the same V-shaped cutting edge irrespective as to the thickness of the blade.

Abstract: A pocket-size sharpening apparatus of the variety carrying sharpening rods disposed in crossed relationship.The sharpening apparatus has a body with a distal face carrying clips to releasably secure a pair of sharpening rods in crossed relationship. A major access opening permits access to portions of the sharpening rods from a proximal face of the body for the purpose of sharpening a blade. The major access opening has a V-shaped portion extended inward from a mouth with convergent edges disposed in parallel relationship to and exposing convergent portions of the sharpening rods from the proximal face. A minor access opening is comprised as a slot extending inward of the body toward the major opening a sufficient distance to expose opposite intersecting portions of the sharpening rods. A peripheral protective lip can line the major and minor openings on the proximal face of the body.

Abstract: A surface mounted sharpening tool having a generally rectangular body which may be formed of one or two sections and which body has blade cavity structure with sharpening blades forming a V-shaped sharpening notch. The body includes a pair of generally parallel guide ridges extending outwardly from the body such that a guide slot is defined between the two ridges or in which the guide slot may be recessed into the body. The guide slot through which the tool to be sharpened is guided is set at a predetermined angle from a right angle to the flat surface of the blade in order to obtain the most favorable sharpening action.

Abstract: A blade sharpener includes a handle to which first and second sharpening members are pivotally attached. The handle has first and second receiving slots for the first and second sharpening members, each slot being on a side opposite the other within the handle. The sharpening members are capable of pivoting from a slot engaging position to an upwardly inclined position, the upwardly inclined position being defined by engagement of a stop within the handle. The sharpening members are inclined in opposite directions resulting in their upper portions being in a spaced relationship. When the blade sharpener is not in use, the sharpening members are pivoted into their respective receiving slots forming a compact unit for storage.
