Abstract
According to this application there is provided a portable sharpening device. More specifically, a portable sharpening device comprising a body portion comprising a surfacing member, a mouth in communication with the surfacing member, arranged to guide an object to be sharpened towards the surfacing member; wherein the device is arranged to sharpen a face of said object by relative movement between the surfacing member and the object to be sharpened and wherein said relative movement is created manually by a user.
Claims28
A portable sharpening device comprising:
- a body portion comprising a surfacing member, an upper wall, a lower wall, and two side walls, wherein the upper wall, lower wall, and two side walls define a mouth;
- wherein the mouth is in communication with the surfacing member;
- wherein the upper wall, the lower wall, and the two side walls are configured to guide an object to be sharpened towards the surfacing member;
- wherein the device is arranged to sharpen a face of the object to be sharpened by relative movement between the surfacing member and the object to be sharpened;
- wherein the body portion further comprises at least three lateral guiding fingers located on the lower wall of an inner portion of the mouth and spaces exist between adjacent lateral guiding fingers of the at least three lateral guiding fingers, wherein the at least three lateral guiding fingers extend toward but do not contact the upper wall so that the object to be sharpened is received between at least one lateral guiding finger and the upper wall;
- wherein the plurality of lateral guiding fingers are arranged to locate the face of the object to be sharpened in an orientation substantially parallel to the surfacing member;
- and
- wherein the relative movement is created manually by a user.

A method of sharpening an object, the method comprising:
- introducing an object to be sharpened into a mouth of a body portion of a portable sharpening device, wherein the body portion further comprises a surfacing member, wherein the body comprises an upper wall, a lower wall, and two side walls that together define the mouth, wherein the mouth is in communication with the surfacing member, wherein the body further comprises at least three lateral guiding fingers located on the lower wall of an inner portion of the mouth and spaces exist between adjacent guiding fingers of the at least three lateral guiding fingers, wherein the at least three lateral guiding fingers extend toward but do not contact the upper wall so that the object to be sharpened is received between at least one lateral guiding finger and the upper wall, and wherein the at least three lateral guiding fingers are arranged to locate the face of the object to be sharpened in an orientation substantially parallel to the surfacing member;
- providing relative movement between the surfacing member and the object to be sharpened located in the mouth, wherein the relative movement is created manually by a user.
