- this is my tutorial video on how to create a forced patina with lemon juice. the test subject is a #206 barlow pattern produced by schrade. items needed will be a tall skinny cup, botlle, or shot glass, a bottle of lemon juice, and a knife made with non stainless carbon steel. if you are forcing a patina on a knife with a bone, horn, ivory, or any other natural material do not immerse the handles in the lemon juice as it may cause discoloration in natural materials. if you are forcing a patina on a knife with synthetic materials: 1. close the blades and place in bottle, cup, or shot glass, 2. fill the cup, bottle, or shot glass all the way so the entire knife is submersed in lemon juice , 3. leave knife to sit in lemon juice for about two hours, 4. remove knife from lemon juice open blades and dry with wrag immediately to produce an even patina. if you let the lemon juice sit on the blade for more than a few seconds it will cause inconsistency in the patina pattern. if you are forcing a patina on a knife with natural handle materials make sure to open the blades and only immerse the blades up to the bolster and use the same procedure. buff off any discoloration from the bolsters with a dry clean cotton wrag. this act of forcing a patina acts in the same manner as the bluing on a gun as it oxidizes the steel and causes an inhibiting in the rusting process. occasionally when the patina wears off after use you can repeat this procedure but, you may want to leave the knife in the lemon juice longer as it takes more time to form a patina on a knife that this has already been done on. make sure to oil your pivot as the lemon juice that gets trapped in the pivot will cause it to rust. if you have any questions feel free to ask. i am not trying to take credit for someone elses work, only my own. i am not trying to sell anything and offer this information for free in hopes that someone else will be able to enjoy this technique. thanks for watching. prometheus19799791

Very cool. You got me to try it. It says no rating allowed but thumbs up for sure.
that's great! it is a very interesting process. one other thing that puts a good patina on a blade is using an onion. it will create such a patina if left in the onion long enough that the patina is able to be peeled off. if it's not left too long it creates the darkest patina i have seen.
@farmerdiddley i'm very glad someone finds it useful. i hope more people do. i tried potatoes before and wasn't really happy with the results. the way i figured this out was i was using my gec steel toenail to cut lemons for a whiskey drink and noticed how quickly it formed the patina. stick a blade in and onion and see what happens. if i ever find onion juice i will use that.
Just did this to my opinel. Awesome.
thanks! i'm glad you were able to find it helpful. how'd it turn out?
thank you.
Thanks for the info! Will be a great help for my carbon steel throwing knives!
i'm glad you found it helpful!
Beautiful. I forced a horseradish mustard patina before I literally stabbed my knife in the lemon though!
to set the record. i had never heard of this being done in my entire life(prior to doing it myself). i came up with this method out of my own creativity and from the ideas of no one else. come to find out people have been putting patinas on knives for awhile. the text below the video contains a more detailed set of instructions if you are interested.
sorry i thought i had replied to you before though, i've noticed youtube has been deleting my comments. how did that opinel turn out?
Do you think lemon juice works better than vinegar?
Absolutely
I tried leaving my blade in alemon for hours and it didnt work
Lemon juice is more concentrated

hello sir... whats a patina
it's tarnish similar to the bluing on a gun, it can be enjoyed for its rustic look or it can also be a rust preventative although it is oxidation which is essentially the same this as rust but, to a lesser extent and for some reason when bringing it nearly to the point of rusting it produced a black/ grey film that acts as a rust inhibitor. verdigris is a form of patina on brass or copper and usually has a green color to it and a wax like texture. on antique items it is important not to remove the patina as it can devalue the item.
oh thanks... do you use ammonia?... also can it be applied to a ecig mod?
i use lemon juice or pcb etchant solution. i don't use ammonia. not sure about ecigs.
then it was stainless steel.
my apologies on getting back to you so late but, the case may also be that it was a nonstainless steel but, that it's chromium content was too high for the steel to take a patina. i have been unable to force one on a couple nonstainless steels such as cpm3v and cpm cruwear.
