Base member for a sharpening device used to sharpen a cutting tool
Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. In some embodiments, an abrasive assembly has a frame, a handle, and a cartridge that supports a plurality of abrasive members each having an associated abrasive surface. A rod affixes the abrasive assembly to a base assembly to facilitate movement of the abrasive assembly along the cutting edge of the tool responsive to engagement, by a user, of the user handle. Each abrasive member is configured to be moved, by the user, with respect to the handle to present each abrasive surface in turn. In some cases, the cartridge is rotatable about a cartridge axis that may be parallel or non-parallel to a central axis of the rod.

Method and apparatus for sharpening a cutting edge of a cutting tool, such as a kitchen knife. A fixture secures opposing sides of a blade of the cutting tool and includes a main body and hinged first and second clamping jaws each having a clamping end adapted to compressingly engage a respective side of the blade. A guide coupled to the main body has converging support surfaces to contactingly engage a back edge (spine) of the blade opposite the cutting edge to center the blade along a central plane of the fixture. A retraction mechanism establishes a clamping force upon each of the respective sides of the blade via the clamping jaws. Further embodiments include a base assembly adapted to receive the fixture, and a swing arm style abrasive assembly to carry out a sharpening operation upon the cutting edge.

A utility blade includes a first blade retention feature positioned on a proximal edge of a tang of the utility blade. The proximal edge is angularly offset from a longitudinal axis of the utility blade. The first blade retention feature is associated with an engagement axis parallel to the longitudinal axis of the utility blade. The utility blade is configured to translate along the engagement axis to cause the first blade retention feature to engage with a first blade engagement component of a blade holder. The utility blade further includes a second blade retention feature positioned on a second edge of the tang of the utility blade. The second blade retention feature is positioned along the longitudinal axis of the utility blade and between the first blade retention feature and a distal tip of a cutting portion of the utility blade.
A utility knife includes a blade, a housing to store the blade, an actuator, and a pinion gear to deploy the blade. The pinion gear includes one or more sets of teeth that are engaged with a fixed rack of the housing and a sliding rack of the blade holder. The pinion gear is also coupled to the actuator, which is configured to linearly translate the pinion gear. As the pinion gear linearly translates between front and back ends of the housing, the pinion gear rotates due to its engagement with the fixed rack. The further engagement between the pinion gear and the sliding rack causes the sliding rack to advance in the same linear direction as the pinion gear by a distance that is greater than the linear distance traversed by the pinion gear, thereby advancing or retracting the blade connected to the blade holder.

Apparatus configured to sharpen a blade of a cutting tool. In some embodiments, a sharpener is provided having a housing and a sharpening stage with at least one sharpening element. Each sharpening element is characterized as a plate and has a curvilinearly extending, concave sharpening surface configured to impart a corresponding convex sharpening geometry to a selected side of the blade during a sharpening operation in which a user retracts the blade along a longitudinal drawing axis through the sharpening stage. A pair of intersecting sharpening elements may be provided to form a substantially v-shaped groove for a ripper-type sharpening stage. The sharpening element(s) may be fixed or tiltable with respect to the housing. The sharpening element(s) may further be moveable in a lateral direction to narrow or widen the v-shaped groove and change the convex geometry and edge angle imparted to the blade.

Apparatus and method for sharpening a cutting tool having a blade portion with a cutting edge, such as but not limited to a kitchen knife. In some embodiments, a powered sharpener moves a flexible abrasive member such as a belt or disc along a neutral plane. A support member contactingly supports a back side of the flexible abrasive member at a medial location along the neutral plane. The support member is positioned adjacent a contact region of an abrasive surface on an opposing front side of the flexible abrasive member against which a cutting edge is brought during a sharpening operation. In some cases, the support member is a stationary or moveable support member such as a pin or roller offset from the contact region. In other cases, the support member is a platen that projects forward to support the contact region.

Apparatus and method for sharpening a cutting tool (150, 160), such as but not limited to a knife. A sharpener (100, 200) has a housing (102, 202) with a sharpener stage (110, 208, 220A, 220B) adapted to facilitate a sharpening operation upon the cutting tool responsive to retraction, by a user, of the cutting tool along a longitudinal drawing axis (135B). A tiltable sharpening mechanism (112, 210) is disposed within the housing adjacent the sharpening stage. The tiltable sharpening mechanism has a central body (130) that is rotatable about a transverse rotational axis (135A, 135C, 135D) nominally orthogonal to the longitudinal drawing axis. The rotatable central body supports at least a first sharpening element (116, 116A, 116B, 116C, 222). In some cases, the central body further supports an intersecting second sharpening element (118, 118A, 118B, 118C). A biasing member (136, 138) exerts a biasing force to urge the central body of the tiltable sharpening mechanism to a neutral position within the housing. The central body can be locked in neutral, positive rake and negative rake positions.

A tool sharpener (100, 200, 300, 600, 640, 650) has first and second guide surfaces (610A, 610B) to respectively support a cutting tool (130, 160, 230) adjacent first and second abrasive surfaces (126, 128, 608, 608A, 608B). A drive assembly (106, 606, 614) moves the first and second abrasive surfaces with respect to the first and second guide surfaces. A control circuit (280, 604) directs a user to place the cutting tool against the first abrasive surface using the first guide surface to sharpen a cutting edge (136, 166, 236) of the tool during a first sharpening operation (686). The control circuit activates an indicator mechanism (298, 612, 622, 644, 664) at a conclusion of the first sharpening operation to direct the user to perform a second sharpening operation in which the user presents the cutting tool against the second abrasive surface using the second guide surface to sharpen the cutting edge (692).

Rotatable edge guide to support a cutting tool during a sharpening operation
Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface.

POWERED SHARPENER WITH CONTROLLED DEFLECTION OF FLEXIBLE ABRASIVE MEMBER
Apparatus (100, 400, 400A, 400B, 700, 800, 900) for sharpening a cutting tool (130) with a cutting edge (136), such as but not limited to a kitchen knife. A flexible abrasive member (112, 406, 702, 802, 930) is supported by a first support member (110, 1 14, 120, 408, 410, 422, 714, 716, 718, 806, 808, 810, 958) and is moved by an electric motor (106, 952). A guide assembly (118, 412, 414, 720, 722) supports the cutting tool during a sharpening operation in which the cutting edge is presented against a contact region (198, 936) of the moving abrasive member. In some aspects, a platen member (604, 730, 820, 900) applies a biasing force to displace the flexible abrasive member toward the contact region beyond an initial tangential plane 615, 911A, 962) established by the first support member. In other aspects, a debris management system uses an impeller (416, 428) to generate an airflow that directs debris from the sharpening operation to a housing cavity (438) in which a magnet (442) is disposed. The magnet is configured to magnetically retain at least a portion of the debris within the cavity.
