Hey guys. I have two brass 110s and have a nickel on the way. I really intended the cross draw sheath for the nickel, but it's still being made. In the mean time I'd like to carry the others and was curious if a finished sheath such as this will cause the mean green. I don't want to put my nickel bolstered knife in a sheath with oxidation in it. Thoughts? I know you'll recommend taking it out and I may, but I'm curious if the process starts as soon as it's in there, over time such as weeks or if it's not even from the sheath? Would brass oxidation effect nickel?

My nickel bolstered 110s haven’t but I don’t store them in the leather sheath for long periods and one is a non stainless Damascus blade which I keep oiled. My 112 with brass bolsters I do the same way and it hasn’t developed any green corrosion. What helps most is if you clean them good after use and apply some oil film it will help resist corrosion especially if the sheath is vegetable tan leather because it is processed with acids for tanning and has a residual amount left afterwards. Remember too that our hands have acids and salts that can cause corrosion so if you handle them a lot you’ll need to wipe them down regular. I wouldn’t worry about it much unless you’re storing them for long periods in the sheath or in a more humid climate or near salty water. Just routine care and keeping them clean and some oil film will keep them looking good.
 
When kept in their buck leather sheaths (black) they tarnish. I can't give an exact time as I haven't carried them in a while (blasphemy!) But they have always come out green. I polish them clean though. Is nickel less likely to tarnish?
 
nickel will tarnish. I've seen it from leaving in the leather sheath.
 
All this worry about oxidation.
Probably why Buck has introduced the knife pouch. It's all fluffy inside. To keep your knife all safe and warm.

Really tho. It's still going to tarnish, but at least the storage environment will not contribute to it.
-or you could:

Coat it with oil, place in a sealed bag to prevent exposure to air, then store in an environment deplete of oxygen.

Enjoy your knife.:D

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.
 
My view:
Green or brown tarnish/patina on the brass just means fewer fingerprints and smudges.

I detest and/or loathe fingerprints and/or smudges on my knives.

Given a choice, I'll take the tarnish/patina.

If the ph is balanced it might but baking soda is a sodium bicarbonate so if you use to much it would be similar to using salt water and caustic. If anything I would use plain tap water as it will balance the ph on that level.
 
Assuming your Carl Thomas sheath is similar to the one in the photo below, the front bolster will fit very tight. It sounds like you want to keep your nickel silver 110 in nice condition, so just beware that the front bolster will probably develop fine scratches from going in and out of the sheath due to its flat construction. Buck sheaths are molded and more forgiving.

I have a couple of the sheaths mentioned here. The front bolster definitely does pick up green corrosion from being stored in these sheaths.

The brass doesn’t get pitted, but it does get a heavy green layer. It polishes right off. In my experience, it takes at least a few weeks to build up.
 
I have never seen a nickel - silver bolster tarnish although sterling silver flatware does tarnish but not with the green monster (VERDIGRIS) that is left for the brass, it gets dull, I made a mistake by taking my ring off and since it is an 1883 Morgan Silver dollar I put it in Tarnex and it stripped the highlighter off and now it is .900 silver. I bought it online and have read Morgan silver dollars were faked but mine is the .900 pure silver and I don't know if it was made out of fake silver dollars. I only paid $75 dollars and others are selling for $125 or more.

I'll take some pics tonight and show you what happens to nickel silver left in sheath. they tarnish.
 
Chrome Tanned vs Veg Tanned Leather. Ill do more homework if one or the other corrodes metal faster.
Vegetable Tanned Leather
Vegetable tanned leather refers to the tannage, or method of tanning the cowhide into leather. It’s called “vegetable” because of the natural materials used in the tanning process like tree bark. It’s also eco-friendly. Vegetable tanning or veg tan as it’s sometimes called, is one of the oldest methods of tanning known to man. It’s literally been around for centuries. It takes about 6 weeks to complete the veg tan process.

Chrome Tanned Leather
Chrome tanned leather is pretty much everything vegetable tanned leather is not. It uses chromium and harsh chemicals. It can be completed much quicker, typically in a matter of days. Because of these differences, chrome tanned leather is almost always cheaper than vegetable tanned leather. It’s no surprise then that chrome tanned leather accounts for about 90% of all leather on the market.

Each Leather Serves a Different Purpose
I don’t mean to disparage chrome tanned leather. There are some good chrome tanned leathers out there. And they certainly serve a purpose. For example, another difference between vegetable tanned leather and chrome tanned is the stiffness or temper of the leather. Veg tanned leather tends to be a little stiffer, though it will soften some as it breaks in. Chrome tanned leather can be very pliable, you can even wad it up in your hand sometimes.

Also, because of the tanning process differences, vegetable tanned hides can be much thicker than chrome tanned hides. This cuts both ways, no pun intended. Sometimes you want a thicker leather; sometimes you don’t.

For example, most boot leather is chrome tanned because you want it to be very pliable to bend as you walk. It can also be a little more water resistant. But most of the high end leather bags tend to be made of vegetable tanned leather because of its shape holding ability, durability, character and the way it ages.

Take a look at some of our bag designs. It would be nearly impossible to achieve some of those shapes, and hold them long term, with chrome-tanned leather. For lack of a better word, chrome tanned leather is a bit mushy. By using thick vegetable tanned leather, we’re able to make bags that are sturdy, hold their shape, and age wonderfully, developing a rich patina.

The Smell
This is perhaps a trivial point for some, but it’s something I notice right away. There is a very different smell for each of these two types of leather.

Chrome tanned leather tends to smell a bit “chemically” if that’s a word. It can be a little bit strong right out of the box. Some might even say nauseating if the tanning was done poorly. Chrome tanned leather that is well made smells okay.

In contrast, vegetable tanned leather has that classic leather smell that is absolutely intoxicating and addictive. You’ll know it when you smell it. If you haven’t smelled a quality vegetable tanned leather, you’re missing out! I don’t want to go too overboard here, but there really is a big difference in smell between chrome and veg tan leather
 
Mak. what then is a natural chamois, to me it looks like a skin of an animal and dries to a hard piece after use?

quoted from the Web.

Genuine chamois leather is a unique and natural product. Selected sheepskins are 100% cod oil tanned to give the luxurious, golden, soft finish that can absorb six times its weight of water. ... Genuine chamois leather is still the most reliable and trusted product for drying and cleaning.

here ya go...all nickel silver all tarnished heavily or starting.....15759328088183392701471668804720.jpg 15759328840136593568023748091769.jpg 1575932924883744284321738535611.jpg

I'd not do this. I make leather sheaths and holsters.

Using veggie tanned leathers. I have only used a baking soda treatment once... on leather I used Vinagroon recipe on to turn the leather black. I used the baking soda to neutralize the vinagroon solution. (Vinagroon is made by taking carbon steel shavings or steel wool and soaking it in white vinegar. The solution permanently blackens leather.)
 
JBMONKEY : I definitely see the tarnish. How did it get that way, were you trying to promote a patine or was the knife left in leather? I'm just wondering that is the first I have seen nickle - silver have a coating or tarnish like what you show. Thank You for the pictures I have always thought that nickle silver did not tarnish. I remember someone on this forum saying that when he received a nickle silver bolster he can now get rid of his polishing supplies or something in that order. I now think my parents flatware and my mother polishing them for a Thanksgiving with all my relatives and bring out the good silverware. Somethings are brought back from the past that you did not realize would help you in the future to understand. Thank You Again JB. You showed the example with some very nice looking knives.

just left in sheath when carrying. bucks sheaths. not all that long either and not everyday. it polishes just like brass and basically tarnishes like brass not quite as fast but does.

now if left polished on a shelf never touched and not carried in leather sheath. kept as a collectible....that might not tarnish...dont know never tried. I dont keep knives that way myself.

glad I could help stop that misinformation and myth of nickel silver doesnt tarnish.
