  • Patent number: 7523557
    Abstract: A carpenter's pencil sharpener is designed for cutting a point on a carpenter's pencil that defines a longitudinal axis and has a maximum width or dimension (MD) perpendicular to the longitudinal axis. The sharpener has a contouring portion defining a rotational axis, a pencil point contour surface and a blade. The sharpener also has a centering portion at least rotationally fixed to the contouring portion. The centering portion has a non-rotating, cylindrical, inner surface and an outer end defining an aperture for receiving the carpenter's pencil. The cylindrical surface has an inner diameter (ID) dimensioned to fit the maximum dimension (MD) of the carpenter's pencil, and is large enough to permit rotation of the carpenter's pencil within the cylindrical surface. The centering portion also has a length (L) generally parallel to the rotational axis and measured from the contouring portion to the outer end for maintaining the carpenter's pencil parallel to the axis.
