Don't drag the file backwards, it ruins the cutting edge, and remember, don't press hard, the cutting edges do the work faster with a light pressure as the multiple edges each take a fine cut rather then trying to scrape off huge amounts with just a few teeth.

Reply 8 years ago on Introduction. Sidewalk chalk is a great method, as is welder's soap stone, and I've heard of people using soap, though I wouldn't recommend it. As for WD, I wouldn't use that since it will cause fine metal dust to cling to the niches in the file.

The "oil" in WD is a fish oil derivative that inhibits rust. The oil is very fine and will hold only the most minute of particles. The next time the file is used, the vibration will break the small particles free, The use of a small wire brush like a 'file card' available at most hardware stores will keep the file clean and clog free.

The file cards are minor tool miracles when it comes to prolonging the life of a file. My "trick" for old, rusty or dull files is to clean them in a bath of vinegar. I use an small mapp gas can similar in size to the tall propane cans used for small torches with the neck cut off.

I stand the files up in the can and then fill with vinegar. Files that have been totally used up or with too many broken teeth, become awls, scribes, or specialty blades.

Teaching these students that a file only works in one direction and you ruin a file by using a sawing action was a tough sell.

My grandfather believed one of the most useful things to have in the workshop was a load of candles. Rubbing a woodscrew on one would make it go in easier, on a saw would make it get caught less, and on a file it would make it easier to clean afterward. Reply 11 years ago on Step 3. Your grandfather sounds like he was a wise man.

I still use this trick today. My grandfather told me keeping pennies in your toolbox helps prevent rust. Whether this was ever true in the days they were made of copper or not, I don't know, but I still keep a couple of pennies in each of my toolbox drawers as a sort of tribute to the old man's esoteric wisdom. So maybe he heard it from someone in the USA? The only other mote of wisdom that springs to mind was to place a small square of cloth between the drill bit and metal when drilling through a sheet to prevent it chattering and making a ragged hole.

Seems to work, though I'm unsure if the cloth needs to be oiled or not for it to. My mom kept a sacrificial galvanic plate in her silver ware box to keep the tarnish down.

I don't see why the same principle would not work in a tool box. I don't remember my chemistry, but if copper is more chemically active than iron, then keeping a couple of pennies outside is still a good copper plating in a drawer should work. If the pennies get to oxidized, replacing them or polishing the old ones - but no oil covering or anything to keep the oxidation off, the oxidation on the copper is what is helping, by keep the other metals from oxidizing.

Also the little bags of water absorbing material helps. Those can be 'recharged' in a toaster oven by raising the temperature to a little above C or F for a while an hour or so to just above the boiling point of water. It should drive off the moisture and let it absorb more. Doing this regularly very few months can help too. Let them cool and toss them back into the drawers!
