A punch is a tool used to indent or create a hole through a hard surface. They usually consist of a hard metal rod with a narrow tip at one end and a broad flat "butt" at the other. When used, the narrower end is pointed against a target surface and the broad end is struck with a hammer or mallet, causing the blunt force of the blow to be transmitted through the rod body and focused more sharply onto a small area. Typically, woodworkers use a ball-peen hammer to strike a punch.

👉 Punch (tool) in the context of Punchcutting
Punchcutting is a craft used in traditional typography to cut letter punches in steel as the first stage of making metal type. Steel punches in the shape of the letter would be used to stamp matrices into copper, which were locked into a mould shape to cast type. Cutting punches and casting type was the first step of traditional typesetting. The cutting of letter punches was a highly skilled craft requiring much patience and practice. Often the designer of the type would not be personally involved in the cutting.
The initial design for type would be two-dimensional, but a punch has depth, and the three-dimensional shape of the punch, as well as factors such as the angle and depth to which it was driven into the matrix, would affect the appearance of the type on the page. The angle of the side of the punch was particularly significant.

Punching is a forming process that uses a punch press to force a tool, called a punch, through the workpiece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal, paper, vulcanized fibre and some forms of plastic sheet. The punch often passes through the work into a die. A scrap slug from the hole is deposited into the die in the process. Depending on the material being punched this slug may be recycled and reused or discarded.
Punching is often the cheapest method for creating holes in sheet materials in medium to high production volumes. When a specially shaped punch is used to create multiple usable parts from a sheet of material (i.e. the punched-out piece is the good piece), the process is known as blanking. In metal forging applications the work is often punched while hot, and this is called hot punching.Slugging is a type of metal-punching operation in which the action of the punch is stopped as soon as metal fracture is complete; the punched piece is not removed but is left in the hole.

Throughout the early Middle Ages, the Rurikid knyazes of the Kievan Rus' used unique symbols to denote property rights over various items. They are depicted on punches, seals, and coins of the Rurikids. In contrast to Western European heraldry, where coats of arms belonged to entire families, or were inherited without changes by firstborn sons, Rurikid symbols were personal, with every knyaz devising an emblem of their own for themselves.
