Forcing a patina on 1095 carbon steel (Great Eastern Cutlery)

- Here is a documentation of how I have forced a patina on some of my Great Eastern Cutlery 1095 carbon steel knives. I am by no means an expert, but I thought showing what I did might help someone else who wants to try it. It is a fun project! I've since also tried it on A2 steel (Bark River) and it worked pretty well.

Never knew what the fuck patina was till I watched your video, thanks man I appreciate your fucking videos God bless!!
Excellant! Thanks for the corrective tip about silver polish! Best patina job I've seen. Nothing worse than blotchy patina. Am trying using bar and chain oil to prevent patina. Also hope to aquire silicone gun cloth to use for wiper of blades to preserve integrity of blade. I'd hold on to that all steel lingered pocket knife. If you religiously wipe it off I think you may have an heirloom to pass down to your children. I miss my dads case muskrat pattern pocket knife. The steel liners I think will last longer than the brass liners. Thanks for doing this vidio!
That worked really nice. As for apple cider vinegar, Charlie Campagna wrote in a thread that he forces a patina by marking a line on the glass, so that you can pour the proper level of apple cider vinegar for the length of an individual blade. I don't believe he ever mentioned diluting the vinegar with water, but used it full strength. He said to microwave it, but NOT to boiling hot. He then places the opened blade into the glass so that the tip of the blade is touching the bottom of the glass, and he leaves it sit that way without holding the knife, and moves the blade every few minutes. I believe he said he leaves the blade in there for 10 minutes or longer, depending on how dark ya want the patina to be. Maybe that's why it didn't work for you, perhaps? I really don't know, because I have yet to try forcing a patina in any way yet. He did use all the other steps you mentioned, both before and after, although he never mentioned using a polish to remove darker spots. He said his method creates a very even patina. I think your method works just fine, just thought I would mention Charlie's method, in case it may explain why you couldn't get the apple cider vinegar to work. By comparing both methods, I'm assuming the "hot but not boiling hot" apple cider vinegar requires a longer dip to achieve the desired patina. Thank you for a very informative video. I enjoyed it.
Great breakdown of the process, thanks for this. I'm going to try this on an O1 chefs knife I'm making at the moment - I'll try multiple cycles (including polishing) to try and build up the layers, as it'll be a knife that gets used everyday. Amazed me how quickly this can be done!
I've done this for years with my 1095/1075 CS blades on my Bushcraft fixed blades. It works great and leaves a nice dark Patina to protect the blades. If you do this to any wooden handled knife wrap the wood with plastic wrap... the steam and condensation can soak the wood causing swelling of the wood which can then cause separating from clean transitions, learned that the hard way! If you want to be a little creative and have some fun, you can etch the Patina with yellow mustard. I've used a wooden skewer as a pen and drawn Tiger stripes, waves, dots etc. for a cool design. I haven't tried the silver polish though, will definitely try that to even out the blotching that can occur, Thanks!!!
i just soak a paper towel in white vinegar and wrap the blade then wrap it in cling wrap and after an hour i got a nice dark patina, clean with alcohol and repeat for a perfect carbon patina, as for apple cider vinegar, boil it then dip knife in it while still hot
Just finished setting the dark patina of my GEC #23 by letting it lie in room temperature red wine vinegar for about one hour. But I haven't used the silver foam/polish to uniformize it. Might try it. Thanks, good video.
I seen people use mustard on high carbon steel for a patina , nice method with the distilled vinegar.
I have limited experience with this, but the few times I have done it, there were no problems with leaving the knife immersed in vinegar for 10-15 minutes. The result is a nice even dark grey to light black patina. We are still only talking a few atoms deep of penetration so I do not believe the steel is endangered at all by a longer soak. If you do not like the darker result, you can always polish it off.
As far as cider vinegars go, many are also weaker so you have to leave them soak longer and a short soak as in your demo may show little to no visible results. Look for vinegar with a 4-5% acetic acid concentration to get easy quick results.
The silver polish is a good idea. I dilute my vinegar 1:4 and do not heat it, which lets me control the process better. Tapping the spine against the glass keeps the hydrogen bubbles off and helps with evenness.
Great information thanks for sharing
Give yellow mustard a try on Q tips. Nice end result, patterns, etc.
Good video, thank you.
pickled pear relish works wonderful
Just wondering but what would gun blueing look like . I love carbon steel slip joint folders and used them well over 50 yrs .little rust don't bother me . sharpen easily to razor edge
Now those are some damn fine looking, true pocket knives. None of that Spyderco, Benchmade, Cold Steel, SOG, etc., etc., tactical, flip open, pocket clip, serrations, jumping crap.
I have a Boker single blade lock-back. I cut up steak , apples , pork ribs with sauce , and so on. I let the nasty stick to the knife for hours. I clean the knife with rubbing alcohol . I use Lucas synthetic , because I love the smell of Lucas Extreme on my knives. I know mineral oil is safer.
good video homie
at 4:10 what is that red knife you are holding
I soak a paper towel in vinegar and fold it over the blade, works great.
What brand knives are the folding sheep foot ones in this video? Thanks
GEC
i think the vinegar is supposed to boiling for a more dramatic and dark patina (if your into that) I would have concerns about messing up the excellent temper of a gec and I also personally don't like the almost black patina from boiling vinegar
Boiling vinegar or water doesn't even come close to touching the temper. It's safe all day long. Just in case you ever want to try it yourself.
5:17 is when gets the instructions.
What is that knife in the top left? Under the longer knife, it looks like a knife I want but, I can't find ir
+Kenan Simpson Case makes a version called the "toothpick," this is the Great Eastern Cutlery version: greateasterncutlery.net/blog/patterns/01-15/12-toothpick/
+keegansreviews thanks, I'll be buying one soon and you just sped up the process. So, I owe you my gratitude.
I hate the mirror finish gecs and they don't force a patina as well. if it's wood I just dump the whole thing in vinegar lol, looks great like gun blueing.
Does that damage the wood any?
+Bryce H the couple times of done that it did not, if your leary you could oil up the wood real good first. It will damage the finish on stag and bone though.
so your the guy that necrod that thread on backspring patina lol. nice vid.
+Tim's Tanks excuse the ignorance, what is "necrod"?
Pretty cool demo video. If I could make one suggestion, use 3 in 1 oil instead of WD40. WD 40 would be great for cleaning a Blade or even removing a patina but is a horrible lubricant and rust preventative. Just try it.
Never had an issue with wd40 preventing rust which it's chemically designed to do.
Cut up a bunch of rhubarb it will set a nice patina
What about Damascus blades?
I know this is over 1 year late but I think you might want to change your mind on using hot liquid to force a patina because the heat can damage or at worse destroy the temper.
JohnSmith FakeName ...this comment made me laugh out loud, silly John.
The liquid is no where near hot enough to destroy the temper or damage the blade
*THERE IS NO REASON TO HEAT THE VINEGAR. IF YOU LEAVE IT IN TOO LONG YOU GET ALMOST A BLACK PATINA, BUT IT DOESN'T RUST.*
Thanks!
pickled pear/apple relish
necro a thread. to post in an old thread bringing it back to the top, from the dead, like a necromancer.
+Tim's Tanks Ah yes, got it.
I’m dying for a gec 83. Any interest in parting with one?????
I wish! My favorite pattern of theirs. It will come back around. I've got two of them, and love them both!
Just leave you knife in vinegar for 3 days....comes out beautiful...
Use the knife ! Enjoy the knife and delay cleaning for 8 hours.
will microwaving thsi vinegar/water make my microwave smell and all my future microwaved food taste like vinegar?
no, it is actually a good way to clean the microwave, just wipe it out after microwaving
You can start quickly without giving Alison for us and speaking too much
Cat urine works fantastic
did that all wrong. just leave it in pure hot vinegar with no water for 10 mins, twice and it will have the most beautiful, smokey petina. Why did u mix it with water? Your petinas dont look deep, rich or good at all. Practice on some cheap Mora blades.
Mos Matic why 10 minutes twice? why not 20 minutes once?
Since the blades turned out the way he wanted, he clearly did not "do it all wrong." Don't be an asshat.
