Urine patina? Seriously.

We need some pics in this thread, whether it is weird or not, it'd be cool to see how it would turn out.
 
A patina is the result of age and use...the so called forced patina is a fashion statement.Think distressed leather jackets or acid washed blue jeans.

Not really. A patina, forced or natural, serves the purpose of a less attention grabbing finish but primarily to help prevent rust. Think of it more as the paint on a Spyderco or Benchmade clip. You can let it wear naturally, which results in an uneven and unattractive finish, or you can strip the paint manually which leaves a nice even finish. It isn't fashion over function, it is a choice of style.
 
I think urine will become basic over time. Consider the ammonia smell from the cat box. The patina, as noted, is probably from the salts in the urine. The blueing on metal uses different types of salts.

The forced patina on the clip blade of my Schrade 8OT has proven to successfully minimize the red rust-spotting that's turned up on the other two un-patinated blades (spey, sheepsfoot) in the same knife; that's why I started with the one blade in the first place, to prove the point to myself. If minimizing that ugly rust-spotting, in favor of an even grey patina, is considered to be a 'fashion statement', then so be it. Otherwise, the above statement is nonsense. Some CAN get very creative, if they want to; but it doesn't have to be the result of such motivations. Sometimes a forced patina is just a closely-controlled means to stay ahead of the uncontrolled corrosion that can otherwise occur, when one isn't paying attention. Think 'bluing' on firearms, substituting a harmless & protective black oxide to prevent the damaging effects of red oxide (rust); a forced patina serves the same purpose, when done smartly.

It's not so bad, urine is quite clean. Has been used to treat wounds in closed off combat and survival situations for years. Safer to use/drink than a lot of the water out there. No I don't drink or play with pee, my own or otherwise. ;)

Immediately after the sterility is gone, it becomes a ripe breeding ground for infection. Yea, don't drink or play with yourin, not good. I have a BK7 that I stripped and ultimately blued twice. It looks nice and has not rusted, aside from some mild surface hazing.
 
So did you get this idea from Bear Grylls? (Sorry I had to it was too easy)

But yeah I'm pretty sure there are healthier ways to patina a knife, pissing on it is now the #1 way not to do it on my list as it's never occurred to me before. I've seen guys just cook with their carbon steel knives before and let it take on a patina that way, others force it, and some even let it occur naturally.
 
A few years ago I did this technique for an artwork (a bronze sculpture). Actualy, this tchnique for the first time was used for the French sculptor Auguste Rodin.
