A ski or snowboard edge sharpener may include an abrasive grinding wheel, a belt-driven drive train or direct drive system that connects a motor and grinding wheel drive mechanism and decreases the grinding wheel's speed of rotation relative to the speed of the motor, a grinding wheel mount allowing selection and use grinding wheels of different grits and materials and grinding wheel controls allowing the control of the cut depth and the grinding wheel angles relative to the longitudinal and transverse planes of the ski edge surface to be sharpened. The sharpener may alternatively include a grinding wheel and motor that drives the grinding wheel drive mechanism. Such configurations may allow repeated sharpening of a ski edge at specific/chosen angles with a specific/chosen surface finish. A position lockdown device that is part of each of the control mechanisms and a vacuum system to capture grinding residue may be included.

According to this application there is provided a portable sharpening device. More specifically, a portable sharpening device comprising a body portion comprising a surfacing member, a mouth in communication with the surfacing member, arranged to guide an object to be sharpened towards the surfacing member; wherein the device is arranged to sharpen a face of said object by relative movement between the surfacing member and the object to be sharpened and wherein said relative movement is created manually by a user.

In at least one embodiment, the present invention discloses a manual blade sharpening tool having a longitudinally extending at least partial channel defined by a longitudinally extending first channel wall, a cutter pocket and a distal planar guide surface located in the longitudinally extending first channel wall, and a longitudinally extending cutter having a longitudinally extending first cutter wall, a longitudinally extending second cutter wall and a transverse cutter surface, the transverse cutter received in the cutter pocket such that one of the longitudinally extending first cutter wall and the longitudinally extending second cutter wall abuts the cutter pocket.

A disc system including disc adapted to be held by the hand and moved lengthwise along an edge portion of a ski or snowboard in order to sharpen and/or bevel either a ski or a snowboard side edge or base edge is provided. The disc is held and may be rotated within at least one concentric ring to establish a number of selected angular orientations in a plane transverse to the lengthwise direction when positioned at the side or base edge portion of the ski or snowboard while in contact with the surface thereof.

A grinding machine for grinding tools comprises a support unit configured to support a tool to be ground and provided with members suitable to incline it by certain angle with respect to a horizontal reference plane; and an operating unit that is mobile along a main axis of development of the grinding machine in order to move with respect to the support unit and comprises an abrasive element intended to abrade at least a portion to be ground of the tool. The grinding machine comprises an adjustment system to adjust the inclination of the support unit with respect to the reference plane. The adjustment means system is mobile parallel to the main axis of development to move to a predetermined distance from the reference plane.

The blade holder has a movable plate and a fixture. A rotatable bolt in operative engagement with a block attached to the plate. A motor is in operative engagement with the bolt. The motor rotates the bolt to move the plate towards the fixture to grip a first set of blades until a torque threshold value is reached. The processor determines a number of blades included in the set of blades based on the number of rotations of the bolt. A first grinding portion of a rotating abrasive belt is applied against the set of blades (having width (W1)) to sharpen the set of blades. Sliding a vise sideways a distance (W1) until a second grinding portion is aligned on top of the second set of blades.

The present document describes a blade sharpening system comprising a blade sharpening device, a blade holding apparatus and a controller operatively coupled to the blade sharpening device and said blade holding apparatus to control sharpening of said blade, and methods of using the same.

A skate blade sharpening system used to sharpen the blades of ice skates. The skate sharpener can include a housing that includes an elongated slot for receiving the blade of an ice skate for sharpening, and clamp jaws for retaining the skate. The housing can include at least one slot cover to engage the skate blade. Engagement of the skate blade can be sensed by a controller to enable sharpening operations to proceed. The skate blade sharpening system can automatically operate a grinding wheel and move the rotating grinding wheel back and forth along the lower face of the skate blade a desired number of times to sharpen the skate blade.

A skate blade alignment system used to align a skate blade sharpening system. The skate alignment system can align a grinding wheel for sharpening a skate blade secured within the skate blade sharpening system. A controller can enable alignment operations and control an alignment process.
