A device for sharpening bladed tools comprising a body defining an elongate handle portion adapted to be gripped in one hand by a user, the body having a forwardly projecting support member curved or angled downwardly with respect to the handle portion and fitted with a sharpening element at or near the end thereof, wherein the support member comprises a pair of spaced support arms extending generally parallel to the longitudinal extent of the handle portion, the support arms being positioned to respective sides of the sharpening element and defining an aperture therebetween adapted to accommodate a blade or anvil of a tool during sharpening of a counterpart tool blade.

An acute angle blade sharpening apparatus and method for sharpening blades is configured to sharpen the edge and bevel of a blade at the specific acute angles between 21° and 23°, or about 22° and 23°. The apparatus has a base member forming multiple elongated depressions oriented at 22° and 23°. Multiple elongated sharpening members are fixedly mounted in the depressions. The blade is oriented perpendicular to the first side of the base member and drawn against the sharpening members, to engage at the desired 22° and 23° sharpening angles. A leveling instrument attaches to the blade to verify the blade is oriented at the desired angles. A leveling instrument cavity stores the leveling instrument and fastener. Springs retain the sharpening members in the cavity of the base member when not in use. A clamp fastens the base member to a mounting surface for enhanced stability.

Systems, devices, and methods for providing different types of sharpeners for knives with a removable angle gauge to determine which knife sharpener to use for individual knives. The sharpener can include three angle sizes of honing ceramic dual wheel sharpeners, three angle sizes of edge shaving diamond coated dual wheel sharpeners, and three angle sizes of new edge blade tungsten rod sharpeners. One angle size can cover approximately 13 degrees to approximately 15 degrees, and include 14 degrees. An angle size can cover approximately 16 degrees to approximately 18 degrees and include 17 degrees. And a third angle size can cover approximately 19 degrees to approximately 21 degrees and include 20 degrees. The removable angle gauge can be a generally rectangular plate with a plurality of grooves, that cover an approximately 13 degree groove, an approximately 14 degree groove, an approximately 15 degree groove, an approximately 16 degree groove, an approximately 17 degree groove, an approximately 18 degree groove, an approximately 19 degree groove, an approximately 20 degree groove, and an approximately 21 degree groove.

A grinding- and polishing tool in combination, comprising a stave which has an edge-treatment side comprising a primary treatment area covering a part of its length, and which in the length direction of the stave is followed by an adjoining secondary treatment area covering another part of the length of the stave. The treatment areas are oriented at intersecting planes such that an intermediate angle between adjoining primary and secondary treatment areas is other than 180°. Also disclosed are a tool assembly, an attachment for a food slicer machine, and a method, all of which are unique implementations of the combined grinding- and polishing tool.

An adjustable sharpener including a body having two sharpening slots, a first arm with a first abrasive element connected to a second arm with a second abrasive element, and a third arm with a third abrasive element connected to a fourth arm with a fourth abrasive element. The first and second abrasive elements are positioned in the first sharpening slot, and the third and fourth abrasive elements are positioned in the second sharpening slot. The adjustable sharpener also includes an adjuster connected to the body and an adjustment assembly connected to the adjuster, the first arm and the third arm. Linear movement of the adjuster causes rotational movement of the first arm and the third arm. In this regard, the adjuster allows the user to manually increase or decrease the sharpening angle between the abrasive elements in the sharpening slots.

A device for sharpening a knife. The device includes an enclosure, first and second grinding strips, first and second grinding strip holders, and first, second, third and fourth pendulum rods. Each of the first and second grinding strip holders have a lower section. The first grinding strip holder holds the first grinding strip and the second grinding strip holder holds the second grinding strip. The first and second grinding strip holders are movably arranged next to each another in the enclosure so that the first and second grinding strips intersect to form a movable sharpening slot having a V-shape. The first and second pendulum rods are hinged to the first grinding strip holder at the lower section via a lower joint. The third and forth pendulum rods are hinged to the second grinding strip holder at the lower section via a lower joint.

A blade sharpener has a frame, first and second rods, a first hub, and a second hub. The first and second rods are adapted and configured to engage a blade to be sharpened. The first hub is operatively connected to the frame and the first rod. The second hub is operatively connected to the frame and the second rod. The first hub being rotatable between an outer position of the first rod relative to the frame and an inner position of the first rod relative to the frame. The second hub being rotatable between an outer position of the second rod relative to the frame and an inner position of the second rod relative to the frame.

A tool for steeling a knife includes a frame and first and second steeling components. Each of the components is shiftably mounted relative to the frame for movement between a first position and a second position. The steeling components cooperatively define a knife interface configured to engage and thereby steel the knife. The steeling components are resiliently biased into the first position, with the knife interface moving as the steeling components shift between the first and second positions.

A storage box includes a base having a bottom portion with inner and outer surfaces, and a peripheral wall surrounding the bottom portion to form a storage space with the inner surface. The outer surface has a placing slot and a knife sharpener fixing portion adjacent thereto. When the user places a knife sharpener in the storage space and closes a covering plate, the whole storage box is portable. The knife is sharpened when the covering plate is detached and embedded in the placing slot while the bottom portion is orientated upward, and the knife sharpener is disposed on the knife sharpener fixing portion. The user moves a knife back and forth between the knife sharpener by one hand and puts the other hand beside the covering plate to avoid being gashed by the knife in the knife sharpening process, thereby achieving protection purpose.
