Abstract
A carpenter's pencil sharpener for sharpening carpenter's pencils is disclosed. The pencil sharpener comprises a housing having both a vertically oriented oval shaped bore and a horizontally oriented oval shaped bore extending therethrough. The oval shapes of the bores corresponds to the profile of a carpenter's pencil. The bores are parallel and aligned with respect to each other. A cutting edge resiliently extends at an angle into the path of the bores. The angle of the cutting edge being adapted to allow a carpenter's pencil to be slid within said bore when inserted therein but whittling a carpenter's pencil when withdrawn therefrom.

A carpenter's pencil sharpener for sharpening carpenter's pencils, the carpenter's pencil sharpener comprising:
- a housing, the housing having a vertically oriented oval shaped bore and a horizontally oriented oval shaped bore extending therethrough, the bores being parallel and aligned with respect to each other,
- a cutting edge resiliently extending at an angle into the path of the bores, the angle of the cutting edge adapted to allow a carpenter's pencil to be slid within said bore when inserted therein but whittles a carpenter's pencil when withdrawn therefrom.
A carpenter's pencil sharpener for sharpening carpenter's pencils, the carpenter's pencil sharpener comprising:
- a housing, the housing having a top mounted to a base, the base having a vertically oriented oval shaped bore and a horizontally oriented oval shaped bore extending therethrough, the vertically oriented oval shaped bore overlapping the horizontally oriented oval shaped bore, the oval shape of the bores corresponding to the profile of a carpenter's pencil, the bores being parallel and aligned with respect to each other,
- a razor blade mounted within a blade cavity on the base, the razor blade having a cutting edge extending at an angle into the path of the bores, one or more springs mounted to the top engaging said cutting edge to resiliently extend said cutting edge into the path of the bores, the angle of the cutting edge adapted to allow a carpenter's pencil to be slid within said bore when inserted therein but whittles a carpenter's pencil when withdrawn therefrom,
- a cam mechanism having a handle operatively attached to an eccentric shaft extending laterally through the housing perpendicular to the bores, at least one pin is mounted on a corresponding cam secured to the eccentric shaft, the at least one pin engaging the cutting edge to raise or lower the cutting edge within the bores as the eccentric shaft rotates.
