Abstract
A knife sharpener includes a knife holder in which a knife is inserted so that an edge of the knife is exposed, at least one edge sensor, configured to detect the edge of the knife, at least one abrader, the at least one abrader having a sharpening surface angled to meet an edge of the knife at a sharpening angle of one side of the knife, a motive mechanism connected to the holder and the at least one abrader, and a computing device in communication with the edge sensor and the motive mechanism, and configured to cause the at least one abrader to traverse the edge of the knife using the motive mechanism, in response to the at least one edge sensor. A method for knife sharpening involves directing the abrader to traverse the edge of the knife, responsive to input from an edge sensor.
