摘要： 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.

摘要： 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.

摘要： Apparatus and method for sharpening a cutting tool, such as a knife. A sharpener includes a first support member, a second support member and a hinge assembly. The first support member supports a first abrasive surface and has at least a first guide at a selected end of the first abrasive surface. The second support member supports a second abrasive surface and has at least a second guide at a selected end of the second abrasive surface. A hinge assembly couples the first and second support member to facilitate movement of the second support member relative to the first support member between a closed position and an open position. In the closed position, the first guide is in facing relation to the second guide and the first abrasive surface is in facing relation to the second abrasive surface.

摘要： 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.

摘要： Method and apparatus for sharpening a cutting tool. In some embodiments, a sharpener has a guide assembly adjacent a moveable abrasive medium. The medium is advanced at a first speed relative to the guide assembly during a coarse sharpening operation in which a user presents the cutting tool against the medium to shape a side of the cutting tool and generate distended material from the cutting edge (e.g., burrs). The medium is subsequently slowed to a lower, second speed for a fine sharpening operation in which the user presents the cutting tool against the medium to remove the distended material and provide a sharpened cutting edge.
