How To Restore Old Files?

Is there a way to sharpen/restore old files? The classic method for honing is honing, as the name suggests, soaking in vinegar. that it was an etching effect from the acid. And it is known that other acids do the same job and have been used in the past. Two of the best alternatives for easy access are citric acid and sulfuric acid (for example, battery acid). It’s best not to use hydrochloric even if you already have some, many sources talk about the risk of hydrogen deposition when using HCl, so it’s best not to risk it as the files are already brittle enough. worn but only rounded from use and no longer cut well. If there are any scratches/scratches or the teeth are so worn that there are shiny flat patches (hard to believe but sometimes you see old files being used so hard!), you won’t be able to restore them. usable surface. But files are nearly always two-sided, and because this is inexpensive and largely a waiting process, it can be worth it for a file even if it’s just there is a side worth using.Degreasing You said you used a solvent and that’s a good way to start the process as the file must be completely degreased before soaking in acid so that access to the metal is not obstructed, ensuring a uniform result. even. Soak in oven cleaner, or hot washing soda solution. Both are edible to any form of grease and are not harmful to steel. or thinner lacquer.Clean If the files have any blockages, this should be removed prior to etching, again to give the acid full access to the surface of the file.

But some tools that clog the material can be very durable (a typical example is aluminum), so sometimes you’ll have to patiently pick pieces out of your teeth with a needle or other sharp steel tool. . If you use a needle, your hand muscles will thank you for clamping it on a pin or permanently attaching it to a wooden handle rather than just gripping the needle in your fingers. Anywhere from a few minutes to an hour of focused work for each side, but it’s worth every second of the effort. it is possible to do a first clean before doing the degreasing step, but I find that the residue (especially the wood) can be much easier to remove from the file that has been fully degreased before and anyway It’s also easier to see it all.Rust As you might expect if the file gets rusty when soaked in acid will also clean the rust from it, so this is a very useful technique for used files obtained from various sources as you will cleans rust while also improving the way they cut. But don’t expect too much if the file has any heavy layer of rust, after the rust layer disappears, some pitting may be left. While on some tools pitting can be just a cosmetic issue on files, they can affect performance, in worse cases lead to uneven wear or scratches. of the embryo. very quickly (rust) so you should quickly spray something like WD-40 right after to help stop this process.

*Can’t give real guidance on how long it takes to soak a file. For example use vinegar while you can usually get some improvement with just an overnight soak, with some vinegars, on some files you may need to soak for two days or more before you judge. it did its best. The acid being used, the coarseness of the file, and the amount of abrasive all have a huge effect on the time required. So for stronger acids on a fine file you might want to remove them from the soak after just an hour to check progress, with a weaker vinegar on the raw file to start overnight and hope that can It takes longer to get the desired results.

Here are some self-explanatory images of recovering some files I purchased last year:And here they are with the job done, with the handle:Note the characteristic grayish appearance of files processed this way.Commercial sandingThere are commercial file sharpening operations around the world, and some people are passionate about the quality of their work. Some users are so impressed by the results – often saying that files processed this way are sharper than any you get directly from the factory, regardless of cost – that they buy new files and Sent straight to be sharpened before being used. pretty sure these companies don’t perform any form of re-cutting as originally thought, but instead they all use some form of etching. While they may have any additional steps (including post-etching to improve rust resistance), there is no reason to assume that you cannot get the same or good results when etching the your files at home in the manner described.
