A portable planar abrading or honing apparatus embodying components including modified elongated planar support block with flared ends each with holding arrangements and attached to the blocks planar surface are optional material support bases that assist various tensioned flexible abrasive material, described as abrasive tapes that facilitate manual grinding or honing and sharpening of edges upon the abrasive surface.

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 base includes a top surface with an elongate slit formed therein. A grinder, such as in the form of a grinding stone, is located within the base and beneath the slit. The stone is in a slot in an undersurface opposite the top surface. The slot is angled to present a grinding surface of the grinding stone at an appropriate angle for forming a face surface in a trimmer blade at a desired angle. The slit has a flat side and an angled side to assist in having a trimmer blade held vertically and at a proper angle for forming of the face. The base includes a finger purchase area to hold the base adjacent to an underlying surface for stability while moving a trimmer blade within the slit adjacent to the grinding surface to form the face at the desired face angle adjacent to the trimmer blade tip.

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.

A dressing board for dressing a tip end of a cutting blade includes a lower surface to be held on a table and a slanted surface inclined to the lower surface and oriented across a direction in which the cutting blade is movable relatively to the table such that the tip end of the cutting blade moves across and over the slanted surface when the cutting blade is moved relatively to the table.

A glideway crowning plate for creating a crown on a cutting edge of a cutting blade with a sharpening jig including a glideway crowning plate having a concaved curved surface of a predetermined radius placed proximate spaced glides of a sharpening jig. The sharpening jig utilizes a flat sharpening plate or a flat sharpening stone and the sharpening jig is side-stroked on the flat sharpening plate or the flat sharpening stone and the glideway crowning plate imposes a curved path of the predetermined radius on the sharpening jig, the cutting blade, and the flat sharpening plate or the flat sharpening stone to create a crown in the cutting edge of a cutting blade.

A handheld skate blade sharpening tool that has an automatically indexing, rotating sharpening stone that matches the concaved profile of the skate blade retained within a two-piece body member. Screws hold the two-piece body member together to keep the round sharpening stone sized to match the desired concave profile. The sharpening stone will remove metal to match the shape of the stone each time the sharpener is moved back and forth along the blade. The sharpening stone has gears on each end of the stone that match the gears inside the two-piece body. As the tool is moved along the skate blade, the sharpening stone will incrementally rotate within the body when the direction is changed in the reciprocating motion by the user's back and forth movement.
