Chemical etching can be used for sharpening old metal files, but it may cause the edge to become more rounded and the polished sides to develop a mat finish. It is important to protect the cutting edges from the acid and to properly clean the blade afterwards. Additional resources for sharpening blades are available online.

TL;DR Summary
Would there be additional help when filing/sharpening a blade by using extra kits
Would there be additional help when filing/sharpening a blade by using extra kits such as, Imho, isn't it better use a bit of acid/alkaline rather than just nothing, ie. neutral water, or other better suitable chemical liquid ?

Note: I'm zero in such knowledge, just came up in mind when working that in lot pain so to ask here now

Most sharpening is done with a coolant because heating and annealing a steel blade must be avoided. The problem with chemical etching a blade is that the chemical attacks the edge more than the flat face, so it becomes more rounded. The polished sides of the blade may develop a mat finish, which may be difficult to clean and so pose a health hazard.

I only know one situation where a chemical is used to sharpen a cutter. When you need to sharpen an old metal file, use it, then do not clean it before you pickle it overnight in acid. The metal that will be attacked by the acid, will be the bare and rounded part of the teeth. The clogged grooves will protect the cutting edges from attack.

What are you sharpening that is causing you pain? Knives, axes, chainsaws, files, ...?

1. How often should I file/sharpen my blade?

The frequency of filing/sharpening will depend on how often you use your blade and what type of material you are cutting. Generally, it is recommended to sharpen a blade every 3-6 months for light use and every 1-2 months for heavy use.

2. What tools do I need to file/sharpen a blade?

You will need a flat file, a sharpening stone or honing rod, and a lubricant such as oil or water. Some people also prefer to use a clamp or vise to hold the blade in place while sharpening.

3. How do I know when my blade needs to be sharpened?

You will notice a decrease in the blade's cutting ability and performance. The blade may also appear dull or have nicks and chips in the cutting edge. If you are having difficulty cutting through material or notice a decrease in efficiency, it is likely time to sharpen your blade.

4. Can I sharpen any type of blade?

It is important to use the correct sharpening technique and tools for the specific type of blade you are working with. Different blades may require different angles or methods of sharpening. Consult the manufacturer's instructions or do research on the best sharpening method for your specific blade.

5. Is there a difference between filing and sharpening?

Yes, filing is the process of removing excess material and shaping the blade, while sharpening is the process of honing the cutting edge to a fine point. Both are important for maintaining a sharp and efficient blade.
