Kikir

Kikir is the Indonesian and Malay term for a hand file, a manual metalworking tool used to remove small amounts of material from a workpiece. A kikir typically consists of a hardened steel blade with a pattern of teeth and a handle or tang for grip. The tool works by being drawn along the surface, with material being sheared away by the cutting teeth. It is used on metal, but variants and related tools are employed in woodworking and other crafts as well. Filers come in many shapes and sizes to suit different contours and applications.

Common forms include flat, round (rat-tail), half-round, triangular, square, and knife files. Roughly cut, bastard cut, second cut, smooth, and dead smooth describe the tooth quality or “cut,” indicating how aggressively material is removed. Rasps are a related class with coarser teeth designed for faster material removal, often used on wood rather than metal. Choosing the appropriate shape and cut depends on the desired profile, surface finish, and the material being worked.

Maintenance and safety: Keep the teeth clean with a file card or brush to prevent clogging. Dry and lightly oil the tool after use to prevent rust. Store files flat or in a rack with guards to protect the teeth and prevent accidental damage. Use a proper handle on longer files, apply steady, even pressure, and avoid twisting the blade or using it on materials beyond its design to preserve tooth life and achieve a smooth, accurate result.
