13 Piece Needle File Set – 6 Carbon Steel Files and 6 Diamond Files – Cleaning Brush Included – For Metals, Wood and Plastics

Let's fix it firmly! The trick to shaving correctly and easily is to firmly hold what you are shaving.
Move in the correct posture! When filing, file in front of or slightly inclined to the object to be filed. The trick is to push the limes from the chest to the waist, which is easiest to hold the limes.
Get rid of the chips! If you sharpen both the iron file and the wooden file, the shavings will be clogged with chips. To remove chips, use a brass brush with a wire brush to remove the chips without damaging the file. Removing chips is the key to maintaining sharpness for a long time!
