Abstract
An abrasive sharpening system having multiple sharpening stations supported on a base. One of the stations includes ceramic rods having a partial curved outer surface and a pair of flat intersecting surfaces forming a longitudinally extending abrasive edge. The base further supports a flat abrasive stone and a pair of carbide blades for sharpening.
Description
- 1. Field of the Invention
- This invention relates in general to abrasive sharpeners and, more particularly, to a sharpening system having multiple abrasive stations.
- 2. Summary of the Prior Art
- Numerous abrasive sharpeners have been developed in the past for sharpening knives, scissors, tools, fishing hooks, and the like. Known abrasive surfaces may be provided by abrasive rods, abrasive stones, and carbide abrasive elements. Prior art abrasive rods typically are formed as separate cylindrical rods and triangular rods, often supported on a base. Such separate triangular and cylindrical rods are disclosed in U.S. Pat. No. 4,231,194 issued Nov. 4, 1980 to Glesser and U.S. Pat. No. 5,477,753 issued Dec. 26, 1995 to Branscum et al. A slot is also provided in the triangular rod disclosed in the foregoing Glesser U.S. Pat. No. 4,231,194 patent for providing the added capability of sharpening fish hooks. In certain situations a cylindrical rod such as shown in the foregoing Branscum et al. patent ('753) is a more effective sharpening element for straight edged knives than a triangular rod, while the shaped edge of a triangular rod is preferred in many cases for sharpening serrated edges. A flat surface can also be advantageous in sharpening other flat edged knives.
- In the past, separate rods have been needed when a particular knife was best sharpened by a flat abrasive surface, a round abrasive surface or an abrasive edge In addition, prior systems have not effectively combined the benefits of abrasive rods with other abrasive components in a multi-use system to perform a wide range of sharpening techniques in a single economical design. Accordingly, it is desirable in the prior art to provide an improved sharpening system having multiple abrasive components for use with a wide range of implements, including, but not limited to, tools, instruments, scissors, fish hooks, and the like.
- It is therefore an objective of the invention to provide an improved sharpening system having multiple abrasive components or stations. The sharpening system herein disclosed includes a plurality of ceramic rod means having a novel configuration by which a portion of the longitudinally extending surface possesses a curved, partially cylindrical shape and the other portion includes a pair of flat, partial triangular surfaces longitudinally extending on the opposite side. The triangular portion provides a sharp edge and flat surfaces opposite to the round surface on a single unitary rod. The novel rod means herein can provide effective sharpening results for serrated or flat knives and the like dependent on which type of surface is desired. Such a multiple surface rod is convenient to use, provides highly efficient sharpening and is relatively more economical than using separate elements to attain the desired sharpening effects. The advantages of the foregoing configuration of the invention are further enhanced with an elongated groove for sharpening fish hooks or other implements. Although not intended to be so limited, the rods provide a fine abrasive surface.
- The system herein disclosed is further equipped with an improved abrasive stone having an interrupted diamond surface formed from an overlapping hole design. This design speeds sharpening by collecting and holding the metal filings that ordinarily build up during the sharpening process, thus allowing the surface to remain clear and clean. The abrasive stone may also provide a fine grinding surface.
- The abrasive rods and the abrasive stone are protected during non-use by being stored within the base of the system of the invention. The abrasive stone is covered by a removable cover that also serves as a hand guard during use of the abrasive rods for sharpening. A third abrasive sharpener is provided by replaceable and reversible carbide blades that facilitate a course cutting head. The carbide blades provide specifically designed “V” shaped cutting slots that are aligned to deliver the optimum sharpening angle. The invention herein disclosed thus is directed to a 3-in-1 sharpening system capable of optimum results for knives, tools, instruments, fish hooks, and other articles which require sharpening.

FIG. 14 is a right end elevational view ofFIG. 2 showing the abrasive sharpening system of the invention. - Referring now to FIGS. 1 there is illustrated the abrasive sharpening system of the invention, generally designated by
reference numeral 2. InFIG. 1 sharpening system 2 includes three sharpening stations formed by a pair of angularly orientedupright rods 4, acarbide sharpener station 6, and a flatabrasive stone 8, all of which will be described in detail later. Each of therods 4,carbide sharpening station 6, andflat stone 8 are supported on abase 10 which is formed of a durable plastic material and the like. - Referring to
FIGS. 1-3 and 13,base 10 possesses an upperrod support portion 12 for supportingabrasive rods 4 and an oppositeupper portion 14FIGS. 1 and 3 ) for supporting and storing flatabrasive stone 8. Thecarbide sharpener 6 is positioned in a narrowedupper portion 16 ofbase 10 intermediate ofupper portions support portion 12 andupper portion 16 are carried on the top of alower base section 18 having a rectangular configuration with aflat bottom wall 20, a pair of flatvertical side walls 22 and anend wall 24. Thesupport portion 12 includes a pair of interconnectedupper protrusions 26 having a pair ofupper holes 28 to form recessed areas for theabrasive rods 4 as seen inFIGS. 1-3 . Theholes 28 respectively angularly extend intoprotrusions 26 and partially intobase 18 for supporting an end portion ofabrasive rod 4 angularly in an upright configuration for sharpening. Theholes 28 both are formed with V-shaped cut-outareas 30 to better support an insertedrod 4 during use as seen inFIG. 2 . - The
upper portion 31 ofcarbide station 6 includes a V-shaped slot 32 accessible from the top ofupper portion 31 as seen inFIGS. 1 and 3 . As further seen inFIGS. 1-3 , a section 34 ofupper portion 31 is cut-out for receiving aclamp member 36. A V-shaped slot 36 a is formed inclamp member 36 in alignment withslot 32 to create a vertical slot for receivingceramic blades 40, such as shown inFIGS. 1, 3 , 9, and 10. The internal edges 36 b ofclamp member 36 are offset from each other to mount thecarbide blades 40 in side by side relationship when viewed from a plan view. As illustrated inFIG. 10 , thecarbide blades 40 are made from tungsten into flat members having an upperbeveled edge 42 that forms a V-shaped sharpening area 44 between the blades. Theclamping member 36 is removeably secured to theupper portion 31 by screw 46 (FIG. 3 ) to clamp thecarbide blades 40 in place againstupper portion 31 for sharpening. Theclamp member 36 may be removed to permit replacement or reversal of the orientation of thecarbide blades 40. - An
upright guard 48 is integrally formed on the base 10 between thecarbide sharpener 6 andflat stone 8. The vertically endportions 48 a ofguard 48 extend beyond the sides of thebase 8 for protection to the user during sharpening. Astone receiving compartment 50 having a rectangular cross-section is formed on the upper surface ofbase 10 for receiving a lower portion of theabrasive stone 8 for storage and for sharpening operation. Thebase 52 ofabrasive stone 8 is formed of a plastic and includes a flat bottom surface 54 (FIG. 11 ) and a pair offlat end walls 56 and side walls 58. Aflat nickel plate 60 is bonded to the upper surface ofstone base 52 and multiple layers of micron sized monocrystalline diamonds are bonded to theupper surface 62 ofplate 60. Theplate 60 is provided with a plurality of overlappingholes 64 in which the material of the base extends. The presence ofholes 64 having a plastic material adjacent to theabrasive surface 62 speeds up sharpening by collecting and holding the metal filings that ordinarily build up during the sharpening process. - As seen in
FIG. 12 , a protective cover 70 is removeably attached to the base 10 to protect theabrasive stone 8 during non-use. The cover 70 has a modified U-shaped cross-section defining a pair of spaced flat side walls 72 and an integraltop wall 74 and end wall 76. The configuration of the cross-section of cover 70 is correspondently shaped to slide over the end of the base 10 to cover thestone 8 during storage. The cover 70 includes opposed ribs (not shown) extending longitudinally along the internal surface of side wall 72 to be slideably retained inopposed slots 74 present on opposite sides of base 10 (FIG. 1 ). Theopposite end 78 of cover 70 is open and includes an upper projectingend 80. A horizontallateral slot 82 is formed onbase 10 adjacent to guard 48 to receive the projectingend 80 to retain the cover 70 and convert it into a protective guard in the position shown inFIG. 1 . - The
lower bottom 80 ofbase 10 beneath abrasive stone includes a loweropen storage component 82 for the pair of ceramic rods 4 (FIG. 4 ). Thecompartment 82 is divided longitudinally by anintermediate wall 84 to provide a pair ofstorage areas 86 for a respective ceramic rod. Therods 4 are secured by a pair ofwing securement elements 86 a that are rotatable between a securement position (FIGS. 4 and 5 ) to an open position in general alignment with the longitudinal axis ofintermediate wall 84 to facilitate release of therods 4 for use. - Referring to
FIGS. 1 and 5 -7, therods 4 are fabricated from a known ceramic abrasive material. Therods 4 have novel cross-sectional shapes as best shown inFIGS. 5 and 7 . Aportion 100 of thecross-section rod 4 forms a circular outer abrasive surface for approximate 180° to form a semi-cylindrical shape on one side of the rod. Twoflat surfaces 102 are provided on the opposite side of portion terminating in a longitudinally extending edge 104 created by intersection of the flat surfaces 102. It should be apparent that therod 4 is formed as a combined half-cylinder and a triangular cross-section integral with the half cylinder. A longitudinal V-shapedslot 106 extends along one flat surface to sharpen fish hooks (not shown). Theflat surfaces 102 are disposed at an angle of 45° to each other. - In use of the
sharpener system 2, either end of the base 10 can be manually grasped for support while the other hand of the user uses the sharpening stations on the opposite side ofguard 48. The flatabrasive stone 8 may be used to sharpen straight edge blades or other tools and instruments by holding it against the abrasive surface at a selected angle and pushing the blade away from the user for a selected number of strokes while thebase 10 is being held against movement at the other end of the base on a support surface. The opposite edge of the blade can be sharpened by pulling it in the opposite direction for a desired number of strokes. - In use of the
carbide blade section 6 as seen inFIG. 9 , thebase 10 is placed on a flat surface and firmly held by the user at a position over thestone 8. With the knife in the other hand, it is pulled between the cutting heads 40 in the slot from the heel of the knife to the point. The carbide blades are pre-aligned to deliver an optimum sharpening angle. - The
ceramic rods 4 are removed from the storage areas and inserted into the holes with the same sharpening angle facing each other (FIG. 1 and 8). The cover 70 is placed into the position shown inFIG. 1 . While grasping the area of thebase 2 over thestone 8, the blade (not shown) of a straight edge knife is pulled on therod 4 on the right side ofFIG. 4 on either theround surface 100 orflat surface 20 down and across for desired number of strokes. The process is then repeated on the inside of the otherceramic rod 4 to sharpen the other side of the knife. - The triangular edge is best used for serrated edges with the triangular edge sliding in and out of the serrations, even extremely small ones. The knife is placed on the inside of the
rod 4 with serrations thereof facing the triangular edge. Holding the blade at about a 90° angle to thebase 10, the knife is pulled down and across the ceramic rod starting from the back of the knife blade to the lip of the blade. This procedure is repeated for a desired number of strokes to provide optimum sharpening. The foregoing procedure is then repeated on theopposite rod 4 to sharpen the backside of the knife.
