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: A hobby knife employs two threadably engaged forward and rear sections and a blade holder which mounts the knife blade for positioning generally outwardly from the front end. The forward section has a tubular shape with three angularly spaced longitudinal indentations which are traversed by a series of longitudinally spaced ribs. The forward and rear sections are substantially covered by overmold material.

Abstract: The invention features a child resistant, moveable closure member and container device and an overcap and container device. The overcap has opposed end walls and opposed sidewalls, with at least one leading locking pin and at least one trailing locking pin in at least one of said sidewalls. The inner closure may have at least one guiding bar, which extends downwardly from its lower surface, that is compatible in shape with an opening slot that may be in at least one of the sidewalls along the upper body of the container. The container further has a fixed cover portion facing the inner closure with a dispensing opening therethrough. At least one of the container sidewalls may have a closing notch, a stopping notch distal to the closing notch, and an opening notch therebetween.

Abstract: A craft ruler employs a laser module which is longitudinally positionable along the ruler. A laser emits a beam which defines a crafting guideline on an adjacent surface. The angular position of the laser guideline may also be adjusted relative to the straight edge on the ruler. In addition, more than one ruler may be ganged together to form orthogonal lines or a grid.

Abstract: A hand held instrument is provided with a pair of assemblies, a ball bearing mechanism and mechanism housing. The assemblies are pivotally connected and are mechanically assisted by a plurality of ball bearings. The ball bearing assisted instrument prevents debris and foreign material from interfering with the pivoting action. By providing a housing that encompasses the ball bearing mechanism unwanted debris is hindered from entering the mechanism.

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 measuring device having a longitudinally extending polymer portion and a longitudinally extending metal portion secured to the polymer portion. The polymer portion may be molded over one longitudinal edge of the metal portion to thereby permanently secure the portions together. The measuring device may have a longitudinal balance axis disposed between a free edge of the metal portion and a free edge of the polymer portion. The balance axis can be disposed so that when the measuring device is placed on a page the metal portion free edge will contact the page and the polymer portion free edge will be raised. Alternatively, the balance axis can be disposed so that when the measuring device is placed on a page the metal portion free edge and the polymer portion free edge are raised above the page. Pressure on the metal portion will cause the metal portion free edge to contact the page while pressure on the polymer portion free edge will raise the metal portion free edge further off the page.

Abstract: A ruler incorporates a central longitudinal reinforcement strip. The strip has an upper surface which simulates wood grain. A pair of bosses integral with the base are received by openings of the inlay strip.
