A sharpening machine generally includes a grinding wheel having a perimeter that is rotatable about a first axis. The sharpening machine includes an adjustment device adapted to be coupled to a structure of the sharpening machine. A shaft, mounted to the adjustment device, defines a second axis that is generally parallel to the first axis when the adjustment device is coupled to the structure and is movable along a predetermined feed axis toward the grinding wheel. A carousel is rotatably connected to the shaft of the adjustment device. A contouring tool having a counter surface is rotatably connected to the carousel. Movement of the shaft of the adjustment device along the feed axis is configured to translate the carousel and move the contouring tool into and out of engagement with the grinding wheel to facilitate dressing of the perimeter of the grinding wheel to a grinding wheel contour.

The method of claim 1, wherein the length comprises a rocker radius and at least one entry radius, and the profile extends along the rocker radius. 3. The method of claim 2, wherein the profile extends along the entry radius. 4. The method of claim 1, wherein both of the edges end at the bottom end at the ice engaging surface. 5. The method of claim 4, wherein the contoured ice skate blade further includes a second vee defined by the other of the side edges and the second flat meeting at the bottom end, wherein a second acute edge angle is formed between the other of the side edges and the second flat. 6. The method of claim 5, wherein the contoured ice skate blade further includes relief pockets positioned between the bottom and each of the flats. 7. The method of claim 5, wherein the second acute edge angle is different than the first acute edge angle. 8. The method of claim 1, wherein the contoured ice skate blade further includes a relief pocket positioned between the bottom and the flat. 9. The method of claim 1, wherein the bottom is linear in cross section across the width, and a height is defined by a distance between a point formed by a line extending collinearly from the bottom to one of the side edges and the bottom end of the same side edge. 10. The method of claim 9, wherein the width is 0.110 inches and the bottom distance ranges from 0.080 to 0.105 inches and the height is 0.001 to 0.0005 inches. 11. The method of claim 1, wherein the contoured ice skate blade further includes a centerline defined as the midpoint between the side edges along the width, and the bottom is symmetrical about the centerline. 12. The method of claim 1, wherein the bottom and the flat combine to form an elliptical bottom having the shape of an ellipse with a pair of non-identical focal points. 13. A method of contouring a single ice skate blade, comprising: engaging a contouring tool with a grinding wheel to form a grinding wheel contour on a periphery of the grinding wheel; andengaging the grinding wheel contour with the ice skate blade to form a contoured ice skate blade, the contoured ice skate blade having:(i) a first side wall and a second side wall opposite the first side wall,(ii) a flat bottom disposed between the first side wall and the second side wall,(iii) a first flat formed between the flat bottom and the first side wall, the first flat forming a first flat angle with the flat bottom,(iv) a second flat formed between the flat bottom and the second side wall, the second flat forming a second flat angle with the flat bottom, the second flat angle being about equal to the first flat angle,(v) a first bottom edge formed at a junction of the first side wall and the first flat,(vi) a second bottom edge formed at a junction of the second side wall and the second flat,(vii) a first vee formed from the first side edge, the first bottom edge, and the first flat, the first vee defining a first edge angle between the first flat and the first side edge, and(viii) a second vee formed from the second side edge, the second bottom edge, and the second flat, the second vee defining a second edge angle between the second flat and the second side edge, the second edge angle being about equal to the first edge angle,wherein the flat bottom, the first side wall, the second side wall, the first vee, and the second vee are a unitary structure. 14. The method of claim 13, wherein (i) the first flat contacts the flat bottom, (ii) the second flat contacts the flat bottom, and (iii) a first distance defined between a center line and where the first flat contacts the flat bottom and a second distance between where the second flat contacts the flat bottom and the center line are about equal. 15. The method of claim 13, wherein the first side wall, the second side wall, the first vee, the second vee, and the flat bottom are formed from a single piece of metal. 16. A method of sharpening a single ice skate blade having a length adapted to be attached to an ice skate and an ice engaging surface adapted to contact ice, comprising: engaging a contouring tool with a grinding wheel to form a grinding wheel contour on a periphery of the grinding wheel; andengaging the grinding wheel contour with the ice skate blade to form a contoured ice skate blade, the contoured ice skate blade having:a first side wall and a second side wall opposite the first side wall,a flat bottom disposed between the first side wall and the second side wall,a first flat formed between the flat bottom and the first side wall, the first flat forming a first flat angle with the flat bottom,a second flat formed between the flat bottom and the second side wall, the second flat formed adjacent the flat bottom on an opposite side of a center line from the first flat, the second flat forming a second flat angle with the flat bottom,a first bottom edge formed at a junction of the first side wall and the first flat,a second bottom edge formed at a junction of the second side wall and the second flat,a first vee formed from the first side edge, the first bottom edge, and the first flat, the first vee defining a first edge angle between the first flat and the first side edge, anda second vee formed from the second side edge, the second bottom edge, and the second flat, the second vee defining a second edge angle between the second flat and the second side edge,wherein a first line that extends parallel to the first flat intersects with a second line that extends parallel to the second flat, the first line intersecting the second line at the center line. 17.
