A skate blade sharpening tool that has a cylindrical sharpening stone that is positioned directly over the blade and adjusting the slot width in the sharpener using thumb screws to match the blade width. When tightening the thumb screws, the two halves of the tool handle will decrease the slot width onto the blade. This pressure on the blade will force the through shaft and cylindrical stone to be centered over the blade. 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. The sharpener also has a deburring stone mounted to the black of the handheld sharpener.
