These nails were known as cut nails because they were produced by cutting iron bars into rods; they were also known as square nails because of their roughly rectangular cross section. The cut-nail process was patented in the U.S. by Jacob Perkins in 1795 and in England by Joseph Dyer, who set up machinery in Birmingham. The process was designed ...
A marking gauge, also known as a scratch gauge, [1] is used in woodworking and metalworking to mark out lines for cutting or other operations. [2] The purpose of the gauge is to scribe a line parallel to a reference edge or surface. It is used in joinery and sheetmetal operations.

Hardened and ground plug gauge Replaceable thread and plug gauges. These gauges are referred to as plug gauges; they are used in the manner of a plug.They are generally assembled from standard parts, where the gauge portion is interchangeable with other gauge pieces (obtained from a set of pin type gauge blocks) and a body that uses the collet principle to hold the gauges firmly.
Generally, the gauge should match to better than 5%, corresponding to 1" of ease in a 20" width. Similar concerns apply to the number of rows per inch. The gauge can be adjusted by changing needle size, without changing the pattern, stitch, yarn, or habits of the knitter. Larger needles produce a smaller gauge (fewer stitches per inch) and ...
A sewing gauge is a ruler, typically 6 inches long, used for measuring short spaces. It is typically a metal scale, marked in both inches and centimeters with a sliding pointer, similar in use to a caliper. It is used to mark hems for alterations as well as intervals between pleats and buttonholes and buttonhole lengths. It can be also used as ...
Like the simpler marking gauge, a mortise gauge has a locking thumb screw slide for adjusting the distance of the scribe from the edge of the wood. It has two protruding pins, often called "spurs", [ 3 ] which are designed to scribe parallel lines marking both sides of a mortise at the same time. [ 4 ]
