SCA fencing blade tips

Steel wool at fine grades is wonderful for getting rust off if any has accumulated due to humidity. I keep a box in my fencing bag at all times.
My swords are tipped and blunted fencing swords, used for SCA fencing, so with outdoor events, high humidity, and simple time, they sometimes get tiny spots of rust.
A fine metal file also works well to remove burrs which can catch on armour. These burrs (sp?) are usually the result of blade to blade contact, so if you use your weapon and have a blunted one, this might be worth noting.
