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, ...?
