Files and chisels shape material such as wood and metal in fabrication applications. Chisels make straight, even cuts and recesses in metal. Wood chisels are used to remove wood when sculpting and making mortises. Contact burnishers and pocket burnisher clean and restore electrical contacts so a secure connection can be made. Files have knurled surfaces with sharp teeth to shape wood or metal by removing material. File cleaners remove piling, dust, and fine debris from file surfaces to ensure files cut effectively.
