A patina is a controlled rust on a knife. I would describe rust as corrosive and damaging, whereas the patina only affects the outer layer of steel. This, in the end, protects the knife from more damaging corrosion. It can be achieved very easily with everyday use of the blade as long as you remember to keep the knife oiled to prevent the damaging rust and pitting. Unfortunately, this process will take months to years for the patina to form properly.
Forcing a patina is very easy and can be achieved using a wide variety of methods. Basically, when steel comes into contact with an acid it will begin to rust. Well, carbon steel will rust regardless if you want it to; but to get a controlled rusting, dipping the steel into an acid will definitely speed things up.
In this method, I test out a mustard, vinegar, and water solution on a 1095 high carbon steel knife.

Since there are so many ways to do this, I made a series of videos on different ways to force a patina and see which is the fastest, most efficient method. In this series, I demonstrate how to force a patina using common household materials. A lot of people don't want to go out and buy ferric chloride or muriatic acid, so I show what can replace them and what shouldn't even be considered.
