oops, that was supposed to read; what to use to patina SK5 steel? - I swear I do speak english. :)

Anyway... I'm thinking I may try to create a darker finish on my Cold Steel SK5 Larado Bowie, and I'm wondering what household items can be used for this?
I've thought about using gun-blue, but I think a more natural finish would look better on this knife.
 
Anything mildly acidic will do it.
vinegar, mustard, etc.
 
Cooked animal fats and pineapple are very good and leave you with the start of a patina as well as some yummy to show for your efforts. It can be like New Pig Hunter's tales of tactical table wear.
 
hmmm... pig fat and pineapple? I'm not a very picky eater, but I'm not sure that sounds too appetizing! :foot:

I put a patina on a blade by cutting a Summer Sausage up for a meal.

I was rather surprised how that turned out.

It is was streaky, i.e. lines in the direction of cutting.

Since then, the knife has taken on a proper "old butcher knife" patina.

No picts, since no camera.

Use a carbon steel knife and it'll develop a patina sooner or later. Not into making it develop myself.

The guy's screen name is New Pig Hunter; like yours might be BryFry; and I meant cooked animal fats in general, such as trimming fat off a cooked steak. As far as fatty pig and pineapple goes, that's the toppings for a "Hawaiian" pizza. I prefer pepperoni, but yum is yum.
 
No patina on SS blades.... by design.

As stated, anything acidic will do it. It works even better if the acid and blade are warm.

Boil some vinegar and dip your blade in.... poof.

Check your household cleaners ingredients for acids... these will all work.

A weak Ferric Chloride solution works for me if I want fast... but food prep is king for natural.
 
One way for patina is a warm blade with warm vinegar, I forced a patina on my hatchet while cold and wrapped the head in patterned paper towel, left the head with some great random patterns.

very much slowed rust formation.
