A carpenter's pencil sharpener for cutting a point on a flat pencil has a base enclosure and a centering collar rotatably mounted on the base enclosure and cooperatively defining a longitudinal central axis. The base enclosure has a pencil contour surface generally matching a desired contour of the pencil. The collar positions the pencil generally along the central axis during rotation of the collar. A flat blade has a cutting edge positioned along the contour surface at an angle of approximately 10-13 degrees relative to the central axis for cutting against the pencil when the pencil is rotated about the central axis.
