Ladies and gentlemen, children of all ages, today i present to thee, the patina tutorial for knives that are stubborn to patinize.

Materials:

CLR (comes in grey/silver jug, available at hardware stores)
A glass, container, just, jar , whatever.
Paper towel, few sheets
your knife
and a small test tube, beaker or pouring container


Procedure:

Ok, first lets do your setup.


1.take your knife, and find what blade you want to patinize ( if this isnt a word, lets assume it is)
2.lay it on the large container cutting edge up.
3.next, take some paper towel and cut it the same length as the blade, if it is longer thats ok, but you dont want to waste paper towel.
4.Next lay it over the blade so that it folds and covers both sides.
5.After thats done, pour some clr in the small container,
6.after that, pour small amounts of clr onto the paper towelled blade, remember it does not take much clr to water down the paper towel.

7. Make sure that there are as little air bubbles on the blade as possible, you cant really eliminate them all (gas is created in the process) but its better to have less air bubbles in the paper towel.

8. Let the blade sit with the paper towel for a while (half an hour, or more) if you want a real deep patina let it dry, and resoak the towel (this will take a while).

What is happening: The CLR corrodes, and induces oxidization, but the clr is not in such a great quantity that it removes oxygen which is needwed to oxidize.

9. After your done, remove the paper towel and look at the blade (kinda ugly )

10. Wet a piece of toilet paper, or a qtip and rub the blaee, this will get rid of any residue that stays on the blade.

Thats it folks, you should be set with a nice patina that will protect your knife.

I'll have to try that one Aaron. Here is a couple of my kitchen knives that I soaked in distilled vinegar about a year ago.

Hears mine. Squeez a lemon, juice goes in to the test tube, set knife blade in tip first. Let sit for an hour or until required darkness. I washed with baking soda and bingo done. Very even coloring.
 
Yeah, distilled white vinegar. You can buy it in the grocery store for about 2 bucks a gallon. Usually use it for cleaning tile grout and other stuff like windows or greasy counter tops. Works good on high carbon steel for a dark grey to black patina. Lasts quite a while.

What is clr? I have used lots of things to make a patina, but the best for me to date is ferric chloride. I etched two blades today, one a stock removal 0-1 and a forged W-2.
Thanks for the tips on the clr.
 
CLR, may have to try that...

Potatoes, mustard (has vinegar in it) and apples work nicely, too! I have found that just about any fruit or veggie will make a patina, but apples and taters are nice because you can get the whole blade into them at once.
 
Last night I decided to use a gala apple to put a patina on my Old Timer 80T - it worked well in the past with my old 80T. Anyway, I stuck the sheepsfoot blade into it and within 20 minutes it has a nice black and gray patina. After more than 2 hours in the apple, the clip and spey are COMPLETELY unchanged. I think that my 80T has a clip and spey from the Uncle Henry version of the knife.
 
APS - I had a similar experience with my a recently purchased 8OT. I got a patina on my clip but the spey and sheepsfoot were unchanged. I think it is strange that we got patinas on different blades though!
 
i origionally made this post because my 80t was not taking patinas from apples, potatoes, limes, vinegar etc... but clr made it happen
 
I'm tellin' you guys...Quince fruit. or a half rotten/half dryed out apple. Fresh apples or spuds just seal the oxygen out and don't work well. The drier fruits give the darkest stains but don't rust like vinegar has started to do on me.
 
CLR is a heavy duty liquid cleaner. You can buy it in stores but I think that it was first sold on TV. For removing rust stains, tarnish, lime stains, etc.
 
Just as info....I think the name of the cleaner is derived from
Calcium, Lime, Rust...thus CLR :D

Anything acidic, even soda water, will eventually work. Some things just work faster and color differently, in my experience.

Color on...

Bill: I think I remember seeing it on TV now. I am going to check walmart for it. I want to try one in that and one in distilled vinegar. Thank you as well for the information
