A framing square including an integrated protractor feature is provided. The framing square includes a blade section, and a tongue section joined at a corner section. The corner section further includes a pivot opening, to rotatably couple the framing square to a workpiece. The blade section includes an array of marking openings. The marking openings are spaced from each other in the array, and the array is positioned a first distance from the pivot opening along a longitudinal axis of the blade. The marking openings can be sized to receive a particular marking instrument (e.g., a pencil or knife) for use with a particular framing square.

A speed square is provided including a triangular flat plate having measurement markings indicated on at least one face, a T bar affixed to, and extending along, the length of a first side of the triangular flat plate, and an extension element hingedly connected to an end of second side of the triangular flat plate opposite the T bar. The extension element having measurement markings indicated on at least one face, such that the measurement markings of the triangular flat face continue on the extension element.

A device to be used as tool creating a straightedge for scoring or cutting VCT (vinyl composition tile) or vinyl floor tile, comprising of a triangular plate that has flat and smooth side surface edges to be used as a straightedge guide to draw a utility knife or other apparatus along the edge. On one of the right angle sides of said triangular plate and face, is an elongated bar fence that extends at ninety-degree angle outwardly from said triangular plate and face. An optional T-bar fence constructed as an integral part of the Floor Tile CuttingGuide extends only a minimal distance and only far enough from the bottom edge in order that the device can lay flat on a floor tile when it is abutted to the edge or laying off to the side of a floor tile. An optional bar fence on one of the right angle straightedge sides is movable up or down in a ninety-degree angle from said plate and face allowing for the bar fence to lay flat on a floor tile or drop down when off to the side and become a fence that can be abutted to the edge of the floor tile. A preferred embodiment along the fore mentioned sides, there are numeral and corresponding measurement markings indicating distance. Along and by the right angle straightedge side, measurement makings indicate the distance from the bar fence and the edge of the floor tile. Along and by the diagonal straightedge side, measurement makings indicate the distance that the right angle straightedge is from the bottom of floor tile being sized. Such measurement markings on the diagonal are parallel and horizontal to the right angle straightedge side that indicate distance right angle straightedge is from the bottom of the floor tile for easy, quick and accurate measuring for sizing, eliminating the need for a tape measure or other measuring device. With optional recessed, indented or even slightly protruding markings, they are a minimal distance away from the edge allowing for an unobstructed and unencumbered flat and smooth side to guide and to draw a utility knife or other such apparatus along the tool edge. With a preferred embodiment, optionally on the flat face or embedded into the plate of said triangle, is a non slip-slide material made preferably of a rubber material, however optionally it can be made of other material such as vinyl or leather that hold the tool firmly and securely in place preventing movement of tool while using it as a scoring or cutting guide. The tool is constructed preferably of a hard cased aluminum, however optionally it can be constructed of any integrally formed material such as any metal or hard plastic that is solid in nature. It is a tool that is lightweight, compact and easily storable.

A carpenter square including a triangular plate and a base. The base has a corner at an intersection of a first side and first end. The corner extends into a pivot notch defined in a first side edge of the plate. During use, the base's corner may be placed on a side wall of a workpiece and the plate is pivoted about a pivot axis extending along the base's corner. An angular measurement may be marked on the workpiece's surface when a selected angle on the plate aligns with an edge of the workpiece that extends along an intersection of the workpiece's surface and side wall. First and second regions of the plate extend outwardly beyond opposite ends of the base. Each of the first and second regions includes a distance measurement scale and the first region further includes one or more angular measurement scales.

A device incorporating visible alignment features which allow the precision trimming of fabric into geometric shapes of a fixed size is disclosed. The device also allows trimming of fabric figures composed of simpler geometric shapes, including guides for rotary trimmers or other cutting implements to remove excess fabric at the seam created by the most common method of creating such figures, to produce figures of specified size and shape with no measuring required. The device incorporates a plurality of trimming slots and indexing indicators allowing it to be used to produce such figures. A method of using the device to produce multiple final fabric pieces from a single section of base fabric is also disclosed.

A speed square consisting of a three sided isosceles triangle that is used in the construction industry as well as the do-it-yourselfer. Consisting of a lead side of a 90 degree angle, a hypotenuse side with a scale of angular degrees ranging from 5 degrees to 90 degrees. The third side and most important side has a scale of inches divided into increments of , but furthermore and most importantly the third side has a raised edge of that when utilized to be used as a safety guide in the act of cutting a straight line. This also acts as a barrier when using such instruments as a utility knife, thus reducing the risk of injury to the hand or fingerers.

A multifunctional writing device comprising a hollow body, wherein the hollow body comprises one or more cavities configured to store a protractor, a ruler, a set square thirty/sixty-degree (30/60) triangle, a set square forty-five-degree (45) triangle, a compass needle, a USB flash drive, a stylus, and an eraser. A first writing member comprises lead and a mechanical pencil system being provided in a first portion of the hollow body. A second writing member comprising a pen system being provided in a second portion of the hollow body. A magnetic lock attaches and stores a protractor, a ruler, a set square thirty/sixty-degree (30/60) triangle, a set square forty-five-degree (45) triangle, and a compass needle inside a cavity. A protractor, a ruler, a set square thirty/sixty-degree (30/60) triangle, and a set square forty-five-degree (45) triangle are removed from a cavity by pulling rectangular strip top portion.

Embodiments herein are directed to a spatially efficient, multipurpose drawing tool adapted for creating architectural design drawings and capable of drawing lines at regular 15 degree intervals without requiring mechanical reconfiguration. The multipurpose drawing tool is arranged, dimensioned and organized as four sides with a concave vertex opposite three convex vertices, one of which has an angle of 90 degrees and may be quickly manipulated to draw a line at any 15 degree interval, e.g., 15, 30, 45, 60, 75, and 90. The multipurpose drawing tool may also include an aperture having a diameter sized according to a scale for drawing arcs, such as a semi-circular arc depicting a door swing in scaled architectural drawings. The multipurpose drawing tool also addresses a problem of chipped or bent tips for drawing tool vertices (e.g., traditional 30-60-90 triangles and 45-45-90 triangles) by cleaving a portion of each tip.
