Abstract: A knife comprising a housing and a rotating blade carriage pivotably associated with the housing. The knife further includes a compartment in which a plurality of blades can be stored and later advanced from the housing for performing a cutting action, the first end of the blade being exposed. The rotating blade carriage can be rotated with respect to the housing and placed in a second position so that the opposite end of the same blade is exposed for performing a cutting action when advanced. The rotating blade carriage can be selectively locked in the first or second position. A carriage locking lever can be accessible for unlocking the rotating blade carriage for blade reversal. When removal of the used or worn blade is desired, the knife can have one or more blade release members that allow the disengagement of the blade from the knife so that the user can manually remove the blade without the requirement of disassembly or partial disassembly of the knife.

Abstract: A fishing gaff has a handle with an offset portion. A shaft extends longitudinally from the offset portion. Generally equidistantly spaced openings are formed in the shaft to facilitate movement through the water. A hook extends from the end of the shaft. Overmould material along portions of the handle provide offset grip segments to enhance leverage.

Abstract: A utility knife has a receiving cavity which opens through the body. A cartridge comprising a magazine of blades is removably insertable into the receiving cavity. A carrier within the body is manually operable for receiving a blade from the cartridge and positioning the blade for extension through the opening to present a cutting edge. The cartridge may be released from the utility knife body by depressing a button and withdrawing the cartridge. The cartridge is releasably held in place within the knife body and releasable when the blade carrier is in its retracted position and the release button is depressed. When the thumb button moves the blade carrier into its extended position to expose the knife blade, the cartridge is rendered unreleaseable even if the release button is depressed.

Abstract: A cutting implement having a pair of cutting blades and a coating is provided. The coating has titanium chromium nitride and provides the cutting blades with a satin silver appearance. In some embodiments, the titanium chromium nitride coating has a thickness in a range between about 0.3 microns and 0.5 microns, a surface roughness in a range of about 15 to 25 10?6 inch/inch, and a hardness in a range of about 5.7 to about 9.1 gigapascals.

Abstract: A pencil sharpener has an electrical motor which drives a sharpening assembly. The end of the pencil to be sharpened is inserted downwardly into an opening in the top surface. Shavings from the sharpening process are deposited in a drawer-like receptacle below the sharpening assembly. A switch is provided so that the sharpening assembly will not be activated when the receptacle drawer is removed for disposal of the shavings.

Abstract: A rotary trimmer for cutting and/or trimming paper and related sheet material is disclosed. The rotary trimmer comprises a trimmer housing having: (i) a first end portion; (ii) a second end portion; and (iii) a cutting platform having: (a) a first platform; (b) a second platform; and (c) a base platform. The first and the second platforms are pivotably connected at least indirectly to (1) the base platform; and/or (2) the first and the second end portions. The rotary trimmer further includes a blade carriage guide disposed between the first and the second end portions and a blade carriage having one or more cutting blades, and slidably mounted to the blade carriage guide wherein the blade carriage can slide along the blade carriage guide to cut and/or trim a sheet or sheet-like material positioned on the cutting platform. A method of using a rotary trimmer is also disclosed.

Abstract: The present invention is directed to a pencil-sharpening device having a titanium chromium nitride coating disposed on the cutting blade of the device. The titanium chromium nitride coating is metallurgically bonded to the steel blade. The coated blade provides enhanced properties for the pencil-sharpening device.

Abstract: A pencil sharpener case has a rotatable cover which covers a mechanical pencil sharpener. In one position, the cover may be rotatably retracted to provide access to the pencil sharpener. The case also mounts an eraser which may be used when the pencil sharpener is covered.

Abstract: A retractable eraser has an elongated contoured housing which has a longitudinal slot and spaced detents and an opening at one end. A carrier has a button which is depressible so that a catch clears the detents to permit selective longitudinal displacement of the carrier. An oval shaped eraser element is mounted to the carrier and displaced into and out of the housing so as, in one position, to project beyond the housing. Bristles project longitudinally from the housing around the opening.
