A foldable ruler includes a first ruler segment, a second ruler segment pivotally coupled to the first ruler segment, a third ruler segment pivotally coupled to the second ruler segment, and a fourth ruler segment pivotally coupled to the third ruler segment. Each of the first, second, third, and fourth ruler segments includes a first side surface and a second side surface opposite the first side surface. At least one of the first and second side surfaces includes a first set of indicia representing units of measurement. Each of the first, second, third, and fourth ruler segments also includes a top surface extending between the first and second side surfaces. The top surface of the fourth ruler segment includes a second set of indicia representing a plurality of angles.

A device for measuring the distance from a reference point to a laser light beam, the device having measurement intervals defined by indicia and being configured such that at least a section of the device is substantially opaque but able to transmit an amount of laser light such that the opaque section becomes illuminated at the location where the laser light is transmitted, whereby the distance between the reference point and the location of the section where the laser light is transmitted is visibly perceivable.

A point-to-point distance gauge includes a rod-like main body formed by fitting a plurality of cylindrical rods 111, 112, and 113 having different diameters with one another so as to be expandable to a desired length; a spherical-tipped shaft 12 provided on one end 113a of the main body 11 so as to be capable of being folded to a desired angle with respect to the main body 11 and to be capable of maintaining the desired angle, a tip 12a of the spherical-tipped shaft 12 being formed in a spherical shape having a diameter larger than a shaft diameter; and a conical-tipped shaft 13 provided on the other end 113a of the main body 11 so as to be capable of being folded to a desired angle with respect to the main body 11 and to be capable of maintaining the desired angle, a tip 13a of the conical-tipped shaft 13 being formed in a conical shape.

In some embodiments, apparatuses and methods are provided herein useful to quickly and accurately determine shelf notch height for a shelving unit. This is particularly advantageous to determine whether shelves in the shelving unit were installed at the correct height and/or for installing shelves at desired heights. In some embodiments, a measurement member is provided with a bottom offset and shelf notch indicator portions. A horizontal position indicator can then be aligned with a desired shelf notch indicator portion and project outwardly therefrom towards a shelving unit to provide a visual indication of the height of a desired shelf notch.

A multi-functional knitting tool bracelet is disclosed. The invention is comprised of a bracelet assembly worn around the wrist of a user and is configured with a plurality of linked, square members having imperial and metric graduations and indicia. Said members having various apertures to cut yarn, receive crochet needles of differing diameters as well as stitch markers therein. One end of the aforementioned bracelet having apertures adapted to receive and selectively secure a crochet hook and a tapestry needleand another end configured with a counting mechanism to record stitches and rows heretofore. The bracelet is joined around a user's wrist by means of an adjustable, magnetic clasp. Objectives of the invention include aiding the process of knitting, crocheting, quilting, tapestry projects and the like by having popular tools within reach at all times. Specifically, an onboard ruler enhances measuring and can be laid flat against a fabric or substrate; the apertures allow for proper needle selection based on gauge diameter; additional apertures hold stitch markers at the ready; apertures on one end store extra needles and hooks; and a distal end houses flush, counting disks that can be turned with the fingers such that they keep track of stitches and rows etc. Having these onboard tools allows a user to work more efficiently by minimizing pauses normally associated with having to reach for commonly used equipment.
