An adjustable manual abrasive sharpener having a pair of sharpening slots formed in a frame with opposing abrasive arms being pivotally mounted in each of the sharpening slots. A rod is mounted on the frame for rotatable motion and for linear motion long its axis of rotation from a position at which the rod is locked against rotation to a depressed position whereby the rod may be rotated. The bottom end portion of the rod includes a pinion gear which engages a pair of gear racks which are mounted for movement laterally relative to the axis of rotation of the rod. The pair of gear racks respectively engage slots formed on the bottom of the abrasive arms in each sharpening slot. Rotation of the rod causes movement of the gear racks to adjust each pair of abrasive arms with respect to each other to vary the sharpening angle of the abrasive elements.

A pocket abrasive sharpener having a housing formed with a pair of upper slots and a lower open compartment. A pair of abrasive ceramic stones is mounted in one of the slots to form a V-shaped sharpening edge. Each ceramic stone has at least one flat face to abut an adjacent reversed stone to form the V-shaped sharpening slot. The stone has an abrasive cutting edge formed with a radius for sharpening serrated edges and having abrasives surfaces on both sides of the radius. A pair of abrasive blades having V-shaped carbide cutting edges is mounted in the other of the slots to also form a V-shaped sharpening slot. A tapered abrasive of is pivotally mounted on the housing and is moveable from the compartment to an extended position for sharpening knives and removing pins in certain military and civilian rifles.
An electric abrasive sharpener for sharpening edges having pairs of interlocking abrasive wheels formed with opposite abrasive helical threads. Each end of the threads respectively has lead-in section and lead-out section having chamfer edge portion to eliminate kickback. The abrasive wheels of the sharpener is driven by a single phase AC motor connected to a motor drive that steps down the rotational speed of the output shaft of the motor to rotate the abrasive wheels with increased torque.
An electric sharpener having two pairs of interlocking abrasives for sharpening the edge of blades to different sharpening angles. An adjustment assembly simultaneously moves the wheels of each pair either toward or away from each other to adjust the sharpening angle produced by pair of abrasive wheels in a sharpening operation. The adjustment assembly is provided with a rotatable shaft having an external handle which engages a lower platen. The lower end of the shaft is threaded to move the platen in vertical direction to move translation bars affixed to the platen. The translation bars extend through elongated slots in respective pairs of adjustment arms coupled to each pair of abrasive wheels to rotate and vary the spacing between the abrasive wheels and adjust sharpening angles.
