What is a Mill Knife Used For?

The Trusty Mill Knife

Although the mill knife is used for several different applications today, which we will explore a little further, the mill knife was first developed as a tool for leather-workers and cobblers, or shoemakers. These special blades are designed specifically to be able to easily cut and shape leather and rubber materials. The knife gets its name, humbly enough, because it is often used in a mill, or a facility where leather is processed. 

Whenever leather or rubber is being processed by a manufacturer, the ends of the large swatches of material tend to have some dangly bits that serve no purpose to the final product. The trusty mill knife is designed to be able to remove these excess parts from the source material before it can be sold. 

Hand-held versions of this knife have been around for well over a century, and in the intervening years, blade materials and manufacturing processes have allowed for increased durability in the blades. This has allowed for the humble mill knife to find practical applications in other processing avenues, like the following…

Applications

In addition to the traditional applications for mill knives, such as leather and rubber manufacturing, they can also find uses in carpeting, flooring, insulation installation, pottery, tire manufacturing, wood carving, and several other conversion industries. While these blades were originally hand-held, there are many industries today that utilize a mounted version of the blade that helps to eliminate any potential human error or accidental injury. If you are curious as to how a mill knife may benefit your specific conversion process, please feel free to contact the blade experts here at Carolina Knife Co.! We’d love to discuss how these handy blades can make your manufacturing process easier.
