Jewelers' needle files work in one direction and must be used in a push action, filing gently away from you in one direction.If used incorrectly the teeth of the file will round off and dull quickly making them unusable.These needle files sets are fine and delicate, and with proper care and use will last a lifetime, so do treat them with care.Do use a dry toothbrush or a stiff paintbrush to clean them if the teeth become cloggedDo keep them dryDo use them in one direction onlyDo store them on their own, back in their packetDo not bend themDo not put excess strain on themDo not use them in a see-saw, back and forth actionDo not store them where they will become damaged by friction against other tools
