Geoffrey Hawketts has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: A hand tool includes a replaceable cutting portion having an elongate cutting surface, a body and a handle. The body receives displaceable protecting apparatus for shielding the cutting surface of the cutting portion when not in use. A forward distal end of the protecting apparatus contacts a portion of the surface of the object to be cut such that when pressure is applied against the object surface displacement of the protecting apparatus relative to the replaceable cutting portion is effected to expose only as much of the cutting surface as needed to effect the required cut. Alignment means maintain alignment of the replaceable cutting portion relative to the protecting apparatus throughout the cutting. When the cutting action is completed resilience means facilitates return of the protecting apparatus so the cutting surface is no longer exposed.
Abstract: This invention relates to a hand tool. The tool includes a replaceable cutting portion having an elongate cutting surface, a body and a handle. The body receives displaceable protecting apparatus for shielding the cutting surface of the cutting portion when the tool is not in use. The protecting apparatus is adapted at its forward distal end to contact a portion of the surface of the object to be cut such that when pressure is applied by pushing the tool against the object surface displacement of the protecting apparatus relative to the position of the replaceable cutting portion is effected to expose only as much of the cutting surface of the cutting portion as needed to effect the required cut in the object. Alignment means maintain alignment of the replaceable cutting portion relative to the position of the protecting apparatus throughout the cutting action.
