Patina good or bad?

[NikRex16]

I want to do a patina coating on my opinel is there something bad that it those to the blade?

To the contrary, it does a lot of good!

If you over do it (leave the knife in the acid waaaaaay too long) i guess it could create pitting on the blade because of corrosion but other than that you should be fine.

How long is too long

A natural patina acquired by using the knife lasts longer and looks better. So just keep using that blade.

Forced patinas are not asgood as natural ones. If I force a patina I do the following.
1 use a sponge and generously apply mustard by dabbling. You get cool looking pattern this way.
Cover with wet paper towel

Wait 30 mins to 2 hours. I normally wait 45 mins.

If you don't think it looks good then polish it off with a stone and redo

Patina is a form of corrosion, if some haven't figured it out yet. There are different forms of corrosion.

The good thing about patina is that it helps to protect against the more destructive red rust.

FYI "blueing" of knives and guns is another version of controlled corrosion, like patina.

Cut up some acidic foods and use it. It will develop its own natural patina and character.

100% agreed!

Another thing is the difference between rust and patina. Patina is another form of corrosion, means rust. But not that brown-red stuff. It´s another form of rust which protects the steel against the red-brown stuff

In your special case - I would use the knife for some food prep and try to keep the blade dry after using and the patina will come at its own.
