Brass corrosion
Well, I've seen it and dealt with it before. Contumely turning green. I was merely going through a bunch of knives wiping them downward and doing a little oiling and found a few that were actually bad. My Randall model 18 had chunks of light-green corrosion on it equally did 1 of my Silver Stags. I likewise just institute a Kershaw Special Agent turning green. I cleaned up the others already and the Randall appears okay, simply the Silver stag has some impairment. All were stupidly stored in the sheath. I have some folders that are the same way. Seems that the quondam Schrades are very susceptible to this. Sometimes even when stored out of the sheath. The question is, how do I stop information technology. I have so many knives that routine maintenance could take a yr if I go through them ane day a calendar week for a few hours. I oasis't looked at the Randall in years, it was in the back of the safe. It was purchased virtually 1970-71. I'm cleaning them by paw with flitz . It's doing a good chore. Should I wax them afterward? None of them are going back in the sheath. Now I have to dig out all the others and look.

Re: Brass corrosion
The green that you depict is called Verdigris which is the common name for a green paint obtained through the natural patina formed when copper, brass or statuary is weathered and exposed to air over a menses of fourth dimension. It is usually a basic copper carbonate and can exist cleaned just as you did. The most prolific example of verdigris is the Statue of Liberty.
Storing knives and sheaths separately volition retard the procedure but non totally preclude verdigris from returning.
Hope this helps.

Re: Contumely corrosion
Contumely is a problem. I cleared out all the contumely bolstered knives from my collection a few years agone. Got fed up w/ having to make clean them westward/ Simichrome every year or so. Information technology just isn't worth it. I won't even consider buying a pocketknife due west/ brass bolsters, and anything that has been in a sheath is strictly off limits. As well many people brand that same mistake of storing knives in sheaths. You are destroying your knife if it has contumely bolsters and you leave information technology in the sheath.
I tried oiling the bolsters w/ SMKW Coon P Oil, gun oil, you proper name it, nothing stops information technology from my experience. If someone has a certain burn down way to keep it from coming back, I would love to hear it. Then perhaps I could buy some contumely bolstered knives again. Until I find something that works, no more contumely bolsters for me.

Re: Brass corrosion
Knives should NEVER be stored in sheaths under ANY circumstances! Write this on the blackboard 100 times!
Seriously though the trouble of verdigris is non only with the brass guards and bolsters it is more of a problem with the brass rivets and snaps that adorn the sheaths.These tin be a real problem.
To clean rivets and snaps I apply a little Female parent'southward Mag Wheel Polish on a rag and grip the head of the rivet between my thumbnail and middle fingernail(thankfully they are long enough to do then)and rotate them several times. Unremarkably cleans out all of the verdigris and and then I repeat the process with a bare fabric.
I accept however to detect annihilation that volition foreclose this oxidation and I feel that oiling a sheath only exacerbates the problem.Information technology is my feeling that any oil will accelerate the deterioration of leather'particularly the stitching.JMHO folks;your mileage may vary.

Re: Brass corrosion
Biggest issues I've had, have been with sheaths my dad treated with mink oil. I started to wipe my knives with clp, and never accept a problem since. I store them in the sheaths. I don't smoothen my brass, I similar the patina. Best matter is to take your knives out and handle them, then oil/wipe them once in a while. Even better, strap them on and take them out of the firm and utilise them.

I take them out and wipe them as much equally possible, simply I have at least a g. Then the all-time I tin do is routine maintenance. Sometimes I don't go to a few boxes for a year or ii. I don't retrieve I'll be strapping on that Silver Stag Pacific Coast Bowie and getting out to use it anytime soon. Information technology'south huge. I can deal with patina, but when the patina starts pitting guards and bolsters I need to practise something. I'm going to put ren wax on them to attempt and keep the brass airtight. And so I take all the guns to make clean and oil, merely we won't go into that now. Lol

Re: Contumely corrosion
Verdigris and patina are non the same thing. Patina is ok. Verdigris is not. If left on brass it will pit the brass.

Is it anything similar this Silvery Stag? I had never heard the proper name until I came across this one a friend of mine had. He traded it for something then I wound upwardly with information technology.Nicely made pocketknife.Ken

I wrap my brass bolstered folding knives like Buck 110s in a piece of plastic from a Walmart handbag, then put them back in the leather pouch. Keeps the green off them for the nigh part, but not always.

I am going to tell you what I have washed for years on gun holsters. It seems to keep the verdigris at bay pretty well. I first make clean it off the best manner you know how. knife7knut's way should work OK, only I also utilise toothpicks and dental picks to remove some of it. Then I force as much Renaissance Wax equally I can around and behind the rivets and snaps trying to get information technology between the leather and metallic. I then utilise a hairdryer to melt information technology. Information technology volition hopefully run in places where you lot can't go to. ThiIs has worked very well for me.

Re: Brass corrosion
I but found one of mine with it. used Mothers Magazine. They say the Tanic Acid used to treat leather is the cause. Much now may exist vegetable oil treated. Y'all may call this sinful but they utilize a gilded tinted clear lacquer spray to protect horns and other contumely musical instruments. Can be removed. The other mean solar day I plant a Pakistan binder new in the box hidden for years. What always is that like a dried plastic coating they put on the blade before wrapping and aircraft?
Maybe gasoline and a match?

I've got 2 Cadet 110s undergoing a highly intellectual type scientific experiment as we speak. ane treated with Ren Wax, ane without. Both stored in their corresponding, identical sheaths. I figure I'll check on them effectually Thanksgiving and see where I'm at.

Re: Brass corrosion
I approximate I am in the minority, but I similar brass bolsters. I like brass tools or tools with brass mounting too. It does tarnish, but I have not seen brass actually corrode. I am non saying that it does not corrode, but I have some old brass that has seen a lot of utilise and exposure to things, and it is tarnished, not corroded. Heck, when a brass cannon is pulled from the sea after a few centuries, all it needs is a skilful cleaning.
But I can see where a knife with tarnished bolsters would not look that great in a display with some polished nickel argent knives effectually it. The same could be said almost real silver, for that affair - after a year or two of sitting in a drawer my silver stuff looks pretty tarnished. The thing nearly silver and contumely is that if you use information technology looks practiced considering the use keeps information technology polished, so I guess information technology is meliorate for user knives than for brandish knives. I do not see where information technology really matters if a knife tucked abroad in storage is tarnished.

Why oh why would you store a pocketknife in a sheath? Go back and read the earlier posts, NEVER STORE A KNIFE IN A SHEATH.
Or are yous only messing with u.s. OCD type people? Cause if y'all are......
Seriously though, find a better style to proceed the sheath w/ the proper pocketknife. Storing information technology in the sheath is going to damage the pocketknife.
I concur that brass looks groovy on a pocketknife when it'due south been cleaned up. Information technology probably would exist better for utilise than display. After I bought that collection where knives had been stored in sheaths for decades, I can tell y'all westward/out a doubt that the sheath will damage the knife. Not just brass but nickle silver every bit well. The previous owner stored a Case Sidewinder in it's sheath since the eighty'south. It took some major work to become the pits and green stains off those bolsters. If I hadn't known how to practise information technology, it would take devalued that knife past a hundred dollars or more. Plus the leather sheath had dark-green stains that ran all down from the brass button and that would not clean off the leather.
Every Parker, Buck, Case and other knives that had brass bolsters required major piece of work. The problem w/ brass in a collection is that few of united states of america take the time to become in and clean and re-oil the knives we have as often as they demand to be. Once you lot become hundreds of knives in your collection it's a major undertaking. The person who started this said that he has over 1000 knives. That's the problem. You can spend a lot of time cleaning contumely to go on it looking good. For me, it's non worth information technology. And I am okay westward/ limiting my choices to just nickle silver bolsters. There are plenty of knives w/ nickle silver bolsters to collect.

But I tin can run across where a knife with tarnished bolsters would not await that smashing in a display with some polished nickel silvery knives around it. The same could be said most real silver, for that thing - after a twelvemonth or ii of sitting in a drawer my silver stuff looks pretty tarnished. The thing about silver and contumely is that if you lot utilize information technology looks skillful because the use keeps it polished, so I guess it is better for user knives than for display knives. I practice not meet where it really matters if a knife tucked away in storage is tarnished.
Mel, I'm not talking about tarnish here. I'g talking about the contumely actually pitting and degrading. If. Yous dont clean off that heavy green gunk it starts to eat into the brass. If you get to information technology early it will clean upwardly. Look a little too long and it will stain the brass. Wait too too long and it will pit the brass. Just go online and wait at some vintage Shrade LB7'due south or Buck 110's for sale and you lot're bound to see information technology. If you're lucky you tin buff it out, but about of the time information technology's a lost cause.

Ken, I had knives that looked exactly like that in that start collection I bought. That staining will not come out. You are admittedly correct about that.

Ken - I am not maxim that you are wrong. Only that I accept not experienced pitting that I was aware of.
In that location are different formulas for brass, and I expect that some might corrode worse than others. Here are a couple of photos of a Jet-Aer that I bought in 1977. It has been stored in its sheath since about 1980. I dropped it on concrete and pavement dorsum when I used information technology, so at that place are plenty of dings, but when I cleaned the tarnish off one of the bolsters I do non see anything that I think is pitting. It is hard to say what is what, for me at least, and I cannot tell with your knife either.

Wow, I haven't seen that. I knew celluloid was unstable but holy moo-cow. Celluloid is as well highly flammable.
Is at that place anything to practice to prevent that out gassing?

No. (Well, I approximate actually at that place is - remove the celluloid and re-handle before it starts to outgass!
)
Do a search here for celluloid. Lots of discussion and information available, but no "cure".
