Merkintäveitsiä

Merkintäveitsiä, also known as marking knives, are specialized cutting tools used in woodworking and metalworking for precisely scoring lines on a surface. These lines serve as guides for subsequent operations such as sawing, chiseling, or drilling. Unlike pencils, which leave a wider and potentially smudged mark, a marking knife creates a thin, sharp indentation that can be followed with greater accuracy.

The design of a marking knife typically features a thin, sharp blade, often made of high-carbon steel for durability and edge retention. The blade is usually angled or beveled on one or both sides, allowing it to cleanly slice into the material. Handles vary widely, from simple wooden or plastic grips to more ergonomic designs for comfort during prolonged use. Some marking knives have a pointed tip, while others have a slightly curved or hooked blade, each suited for different tasks and material types.

In woodworking, marking knives are invaluable for tasks like laying out joinery, such as mortises and tenons, or for scribing cut lines on lumber before sawing. The sharp cut helps to prevent tear-out, where wood fibers splinter and break away unevenly, especially when cutting across the grain. In metalworking, they are used to scribe lines for cutting, bending, or drilling metal with precision. The choice of marking knife depends on the specific application, the material being worked, and the user's personal preference.
