Two step abrasive sharpener
An abrasive sharpener having a housing supporting a pair of sharpening slots having abrasive elements mounted therein. The bottom of the housing is formed with an open V-shaped groove for supporting the housing on the edge of a table, bench and the like. The bottom further includes a pair of flat bottom surfaces separated by the V-shaped groove for supporting the housing on a flat surface. The V-shaped groove is opened ended and extends along an axis generally perpendicular to the direction that a knife edge and the like is pulled through either slot for sharpening.

BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to abrasive sharpeners, and more particularly, more particularly, to a two-step abrasive sharpener having a bottom V-shaped groove.
2. Summary of the Prior Art
It is well known to use sharpeners for knives having two steps of sharpening, namely a course grind and fine sharpening grind. One problem associated with such sharpeners occurs when a sharpening operation is performed on a surface, such as a table or counter. During the normal sharpening stroke through abrasive elements, the blade of the knife being sharpened often strikes the counter to damage the already sharpened blade and the counter. Such damage requires the user to repeat the sharpening of the blade. Therefore, it is desirable in the prior art to provide an abrasive sharpener capable of avoiding impact between the knife being sharpened and the sharpener support surface.
SUMMARY OF THE INVENTIONIt is therefore an objective of the invention to provide an improved two-step sharpener that avoids impact between the sharpener support surface and the blade being sharpened. The sharpener here employs two abrasive stations created by crossed carbide abrasive blades and crossed ceramic rods. The base of the sharpener of the invention includes a V-shaped open groove on which the sharpener base can be supported on the edge of a counter and the like during a sharpening operation. Such a positioning of the sharpener further provides for a more natural, comfortable sharpening stroke by an individual.
Referring now to
The bottom 20 of housing 4 has a pair of spaced flat base surfaces 22 extending the length of housing 4. The flat surfaces 22 are centrally separated by a V-shaped open groove or slot 24 that extends the length of base 4 generally perpendicular to the direction of movement of the blade being sharpened through slots 10a or 10b and has open ends as seen in
Claims
1. An abrasive sharpener comprising
- a body having at least one sharpening slot,
- at one abrasive sharpening element being mounted is said slot, and
- said body having a bottom for contacting a support surface during sharpening, and
- said bottom is formed with an open V-shaped configuration.
2. The abrasive sharpener according to claim 1 wherein said V-shaped configuration of said bottom of said housing forms a pair of angularly arranged support surfaces.
3. The abrasive sharpener according to claim 2 wherein said V-shaped configuration is formed by an open V-shaped groove.
4. The abrasive sharpener according to claim 3 wherein said V-shaped groove is open-ended.
5. The abrasive sharpener according to claim 4 wherein said bottom of said housing includes a pair of flat lower surfaces, said flat lower surfaces being separated by said V-shape groove.
6. The abrasive sharpener according to claim 4 wherein said V-shaped groove extends along an axis generally perpendicular to said at least one sharpening slot.
