A skate blade sharpening system includes a chassis having a slot for receiving a skate blade, and a skate blade retention mechanism for retaining the skate blade in a sharpening position. The skate blade retention mechanism includes an actuator and a pair of jaws on respective sides of the slot, the jaws being coupled to the actuator and configured for symmetrical opening and closing movements about a centerline of the skate blade. The jaws are secured to the chassis by guide blocks extending though corresponding guide slots of the jaws. The guide blocks have respective angled surfaces contacting corresponding angled surfaces of the jaws permitting the jaws to slide on the guide blocks when the jaws are open. The angled surfaces are oriented in a manner urging the jaws upward against a surface referenced to the chassis as the jaws are urged to a closed position by the actuator.

1. A skate blade sharpening system for sharpening a skate blade, comprising: a chassis having an elongated slot for receiving the skate blade into a sharpening position; anda skate blade retention mechanism for retaining the skate blade in the sharpening position, the skate blade retention mechanism secured to the chassis and including an actuator and a pair of elongated jaws on respective sides of the slot, the jaws being coupled to the actuator and being configured for symmetrical jaw opening and closing movements about a centerline of the skate blade in the sharpening position, the jaws being secured to the chassis by guide blocks extending though corresponding guide slots of the jaws, the guide blocks having respective angled surfaces contacting corresponding angled surfaces of the jaws adjacent the guide slots, the angled surfaces being oriented in a manner urging the jaws upward against a surface referenced to the chassis as the jaws are urged to a closed position by the actuator. 2. A skate blade sharpening system according to claim 1, wherein the skate blade retention mechanism further includes a biasing mechanism configured and operative to apply a bias force to symmetrically bias the jaws toward the closed position with sufficiently high force to retain the skate blade in the sharpening position when the skate blade is located between the jaws as so biased, and wherein the actuator is configured to actuate the jaws against the bias force to an open position under user control to permit insertion and removal of the skate blade. 3. A skate blade sharpening system according to claim 1, wherein the guide slots and guide blocks are co-configured to provide for (i) a first position of the jaws on the guide blocks in which the jaws are spaced from the surface referenced to the chassis and can slide on the guide blocks, and (ii) a second position of the jaws on the guide blocks in which the jaws contact the surface referenced to the chassis and the angled surface of the guide blocks reflects the biasing force and a reaction force from the skate blade in the sharpening position to urge the jaws against the surface referenced to the chassis. 4. A skate blade sharpening system according to claim 3, further including spacer blocks attached to a surface of the chassis and to which the jaws are secured, the spacer blocks providing the surface referenced to the chassis. 5. A skate blade sharpening system according to claim 1, wherein the jaws have generally symmetrical configuration and motion with respect to each other, one jaw being secured by at least two guide blocks to provide a fixed positional reference for the skate blade in the sharpening position, the other jaw being secured by one guide block in a manner permitting the other jaw to conform its position to the position of the one jaw for uniform clamping force across the skate blade. 6. A skate blade sharpening system according to claim 5, wherein the one guide block securing the other jaw is secured at the reference surface using a fastening method leaving the one guide block free to pivot to allow the other jaw to dictate its position. 7. A skate blade sharpening system according to claim 6, wherein the fastening method includes a shoulder screw in a counterbored hole. 8. A skate blade sharpening system according to claim 1, wherein a jaw closing direction is perpendicular to a direction of a jaw actuating force, and wherein the guide slots are angled to translate the jaw actuating force to a clamping force in the jaw closing direction. 9. A skate blade sharpening system according to claim 8, wherein the jaw actuating force is a pulling force configured to pull the jaws up the respective surfaces of the guide blocks to urge the jaws against the surface referenced to the chassis. 10. A skate blade sharpening system according to claim 1, further including a grinding wheel configured for movement along the slot including a lower edge of the skate blade in a sharpening operation, and wherein the surface referenced to the chassis is spaced from a bottom surface of the chassis to cause the grinding wheel to contact the lower edge of the skate blade away from the bottom surface of the chassis. 11. A skate blade sharpening system according to claim 10, further including spacer blocks attached to the bottom surface of the chassis and to which the jaws are secured, the spacer blocks providing the surface referenced to the chassis.
