A snowboard edge tuner, including a locking mechanism and a case having a base and a connecting base mutually connected; a first through hole passing through the connecting base and a second through hole passing through both the base and the connecting base are in communication with each other; the locking mechanism includes a sliding block and a first rotating component; the sliding block includes a first pressure plate, a second pressure plate and a first inclined surface; the base includes a second inclined surface corresponding to the first inclined surface; the first rotating component is rotatably fitted on the case, rotates and drives the sliding block to move along the second inclined surface, such that the first pressure plate presses against a sharpening block in the first through hole or the second pressure plate presses against the sharpening block in the second through hole.

The method is for profiling blades with a belt grinding profiling machine. The blades are mounted into a vise. A vertical position of the template is adjusted by rotating the rotatable knob. The motor is turned on to rotate the grinding belt over the grinding wheel. The guide wheel engages the underside profile of the template. The guide wheel of the template guides movement of the grinding wheel mounted on the common axle by moving the guide wheel along the underside profile of the template. The grinding belt grinds material off the underside of the blade until a portion of the underside profile of the template is copied to the underside of the blade.

An automated self-service machine for the selective sharpening of ice skate blades utilizes a pair of actuating mechanisms that operate a sharpening device. The sharpening device is disposed within a base and accessible only when activated. A user wearing the ice skate blade to be sharpened steps onto the base and inserts the ice skate blade within a slot where the sharpening blade resides. A control system is configured to enable a user to interface with it to provide the activation of the sharpening device and to enable financial transactions.

Computer-implemented method of operating an ice skate blade grinding apparatus, which comprises determining a number of contiguous ice skate blades inserted into the apparatus; and setting an operating parameter of the apparatus based at least in part on the determined number of contiguous ice skate blades. This allows optimized sharpening and profiling of multiple blades at a time.

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.

An automated apparatus for grinding an ice blade on an ice skate comprises a processor, an input device in communication with said processor, a skate holder, a non-contact measuring device in communication with said processor, and a grinding device in communication with said processor. The input device permits a user to select an ice blade grinding option. The skate holder releasably holds at least one said ice skate to said apparatus. The non-contact measuring device is configured to measure a three-dimensional (3D) shape of said ice blade. The grinding device is configured to perform a grinding action on said ice blade in said holder based on said selected ice blade grinding option to change said 3D shape of said ice blade to a desired 3D shape.

An ice blade measuring system comprises a holder for holding an ice blade in a measurement position, and a non-contact measuring device operationally positioned relative to the holder to measure at least a three-dimensional (3D) shape of an ice contacting surface of the ice blade held in the holder. The non-contact measuring device is configured to create a dataset which corresponds to the measured 3D shape. The system further comprises a data storage means operatively connected to the non-contact measuring device to record the measured dataset.

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.
