Recommendation? Carl Thomas jr sheath & oxidation

Well you have along with my Mother brought back something that was hidden in my brain until you showed me that nickel - silver does tarnish and my mother polishing silverware long ago that was brought back to memory because of you JBMONKEY. Those are fond memories of my family that were long hidden in my memory and having medicated Dementia this image popped into my vision through all the medications. I really Thank You. It was a very good experience.

sure she wasnt polishing real silver or plated silver silverware? my momma made me do it as a kid for every holiday when it came out with the fancy china for guests.....

this is 925 sterling lighter i use for my cigars.....pocket wear in watch pocket of my jeans keeps most of the tarnish at bay.
scratches not so much though...threw Buck i have in my pocket today in the pic....15760021427478999976192312221047.jpg 15760021740521038021748365148771.jpg

covered brand as advertising isnt meant for this post more on topic of silver and nickel silver and tarnish.....
 
Left unused my ns has not tarnished.
I have ns edc's that have tarnished, especially orange juice not cleaned off. But it does come off easily, easier than tarnished brass.
 
Yes it is silver, Sister has it. I assumed nickel/silver was part silver but looked it up and it contains no silver, Hmmm. The highest percentage is copper at 62 %, 20% zinc, and 18% nickel. Pardon my faux pas - (mistake). The silver flatware was a gift to my mother and father on their wedding day and came in a big case. with velvet inside and separators for the knives, spoons, and forks.

GPyro: everybody makes mistakes this was not big, I just needed more info which I did find when I made a Google search.

Since baking soda neutralizes acid, i wonder if giving the sheath a bath/soak in baking soda and water would help slow down the verdigris? I would assume something was done after the leather tanning process to neutralize but maybe a little more might slow it/help it.

I disassemble my leather sheathes including Buck's, and melt in a coat of SnowSeal, then re-stitch them. Extends the life of the sheathes considerably and I don't notice any green oxidation, just normal darkening of the brass if I don't use them for a while.
 
Most so called Nickel Silver is just a white brass. They vary the proportion of Zinc to Copper to control the color. Gold color = more Copper. White color = more Zinc. The corrosion of Copper yields the Verdigris (green salts). A common N/S formulation (above) is 62% Copper. Nickel is fairly resistant to corrosion but is expensive and hard to work. Silver reacts with Sulfur to form black salts. You need a knife with 18k white Gold, Platinum, or stainless steel bolsters.
Store your Titanium knives in leather and your brass knives in Nylon.
 
tiguy7 : There is some very good info in what you wrote, especially on how to store Titanium and Brass knives. Does Nickel Silver melt like brass does? The new buck pouches could be another way to keep verdigris away. I have many knives in pouches and there is no need to polish.

The melting point of various Copper/Zinc (brass) alloys changes with the ratios. More Copper raises the MP. More Zinc lowers the MP. Nickel additions would raise the MP. Bronze (Copper/Tin) alloys generally melt at higher temperatures than brass alloys because they are about 90% Copper and 10% Tin. Brass alloys are around 60% Copper and 40% Zinc.

Tiguy, I like your description of color variation.

Here is the Wikipedia description of "Nickel Silver". So many people believe that it's actually a silver alloy. Including knife people, as the term is often included in the primary description of many knives. As many of us learn eventually, pretty much anything can patina, even stainless. Maybe we need to make some bolsters in solid 24 karat. Should handle leather storage quite well. :D

----------
"Nickel silver, Maillechort, German silver,[1]Argentan,[1] new silver,[1] nickel brass,[2]albata,[3] alpacca,[4] is a copper alloy with nickeland often zinc. The usual formulation is 60% copper, 20% nickel and 20% zinc.[5] Nickel silver is named due to its silvery appearance, but it contains no elemental silver unless plated. The name "German silver" refers to its development by 19th-century German metalworkers from the Chinese alloy known as paktong (白銅) (cupronickel).[6][7] All modern, commercially important nickel silvers (such as those standardized under ASTM B122) contain significant amounts of zinc, and are sometimes considered a subset of brass.[8]"
