wait is this the spanish special forces knife? It seemed fine why do you need to darken it? I think TOPS gives people the option to camoflauge knives I don't know if they do any kind of process to darken the blade as well but I don't think they would carbon steel rusts easy. Maybe theres a special chemical that can darken it.

Carbon steel is simple to darken depending on the shade you want.

The easiest way is to simply peel an apple or rub it with orange juice. The acid has a natural darkening effect.

Second, you can use mustard or wipe the blade with vinegar.

Third, you can go to Walmart and buy a bottle of gun blue. Follow the directions on the bottle and you will have a deep almost black color.

I use my carbion steel knives around the kitchen and they take on a rich dark color from everyday use.

Wallmart has spray paint too.


Why does it need to be dark?

hey king guess what I just discovered a bench grinder in my barn. It's an old general electric bench grinder from the 60's. I bought new grinding wheels for it and asked my dad to inspect it to make sure it was safe. Its incredible how well built it is the thing works perfectly. Sometimes I think things were made better back in the day than they are now. It was worth cleaning that damn barn after all now I have a large workshop for working on knives.
