Abrasive sharpener
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 slot. 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 abrasive 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 rod 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.
1. An abrasive sharpener comprising
a housing having a pair of slots,
a pair of flat blades being mounted in a juxtaposition relationship in one of said pair of slots to form generally V-shaped opposed first abrasive edges creating a pre-set angle for sharpening,
said first abrasive edges being formed from an abrasive carbide material,
a pair of flat stones being mounted in juxtaposition relationship in the other of said pair of slots to form second generally V-shaped opposed abrasive edges creating a second pre-set angle for sharpening,
each of said pair of flat stones include a triangular cross-section configuration,
said pair of flat stones having surfaces bearing in contact with each other for providing a generally continuous abrasive path through said second V-shaped abrasive edges, and
said pair of flat blades and said pair of abrasive edges are removeably mounted on said housing and may be reinserted in reverse orientation,
said housing is provided with a first sloped shoulder for supporting a surface of one of said abrasive stones, said housing includes a removable retention member bearing against one of said abrasive stones, said retention member having a second sloped shoulder for supporting a surface of the other of said pair of abrasive stones.
2. The abrasive sharpener according to claim 1 wherein said retention member is slideable on said housing.
3. An abrasive sharpener comprising
a housing having
a pair of flat blades being mounted in a juxtaposition relationship in one of said pair of slots to form generally V-shaped opposed abrasive edges sharpening,
a pair of overlapping flat stones being mounted in juxtaposition relationship in the other of said pair of slots to form a second generally V-shaped opposed abrasive edges for sharpening,
said housing having an open bottom compartment,
an elongated abrasive rod having an enlarged end portion being pivotally mounted on a lower portion of said housing for movement between a stowed position within said housing to an outward extended position for sharpening,
said housing having a pair of spaced walls adjacent said open bottom compartment,
said spaced walls respectively having spaced protrusions extending into said compartment and respectively being spaced by a distance less than the width of the enlarged end projection of said abrasive rod for retaining said abrasive rod within said compartment in snapped relationship, and
said spaced protrusions further retaining said enlarged end projection of said abrasive rod in snapped relationship for retaining said abrasive rod in said extended position.
4. The abrasive sharpener according to claim 3 wherein said rod is tapered and includes a tip for removing pins from rifles.
5. An abrasive sharpener for sharpening flat and serrated blades comprising
a housing having at least one slot,
a pair of flat stones being mounted in juxtaposition relationship in said at least one slot to form a generally V-shaped opposed abrasive edges for sharpening, said abrasive edges being formed with a radius to sharpen flat blades and serrated blades,
said stones having a triangular cross-section configuration and includes a plurality of abrasive edges for reorientation of said flat stones on said housing,
said housing being formed by first and second half portions pair being secured together,
said first half portion having an upper cut-out area,
a retention plate being removeably secured to housing in said cut-out area,
said retention member for bearing against one of said stones in said secured position,
said second half portion of said housing and said retention member each include a pair of aligned open ended slots, and
said second half portion of said housing and said retention member each include a sloped surface for respectively contacting one of the edges of a respective one of said pair of triangular abrasive stones.
