Multi-tools with a file

File

— the saw blade installed in knives and multi-tools is usually small and does not exceed the main blade in length. Its purpose is to work with materials for which an ordinary knife is poorly suited — boards of small thickness, ropes and ropes, rubber, sometimes metal, etc. Do not confuse a file with a serrated blade — despite the similarity, these devices still use slightly different principles, and are taken into account separately when calculating functions.
