42 blade stain and alternate sheaths?

[blade_420]

Hey Y'All,

I was having to do an Acid Wash of some tile last week, and then I noticed that there is a stain on the blade. I was using Muratic acid, which has about 30% hyrdrochoric acid.

Just to let you know, that stainless, or "12C27" (whatever that means), can still stain.

The handles seem unaffected.

I was thinking of (forceably if necessasary) taking my 42 apart and polishing the blade.

On that note, will the inking of the butterfly ->disapear<-?

and now for something completely different...


Clay, will you be comming out with different sheaths (Kydex inverted V) for the newer bali's comming out?

I have one of the SWAT tiger balis, and was finding it kinda hard to cary.
The "sheath" that comes with it is kinda crap.
I was specifically thinking about the Tachyon, the SWAT bali, and any newer ones???

I was also wondering if you would do "combo" sheaths. Like SWAT/42 or TAC/SWAT or 42/TAC?

Just a thought, since I'd kinda like to cary something quality if/when I re-condition my 42, and I have grown very accustomed to the inverted V sheath.

Stainless steel is just that: stain less. 30% hydrochloric acid is pretty strong stuff.

The butterfly logo tang stamp is laser etched. You'd have to polish pretty hard to get it off.

I have had a fascination with titanium for a long time now. I used to work in the metallurgy field, and discovered many interesting things about titanium. It is totally inert, meaning not readily changed by chemical or biological reaction. You can soak it in any type of acid without effecting the molecular structure of the metal, it reacts to no chemical or environment (that we know of). My two cents worth anyway.

Ti does react. In fact, it rusts. But, that process happens very, very slowly. You can accellerate it by heating the Ti. The result can be pretty colors since the Ti oxide layer that forms on the surface is very thin and defracts light.

But, Ti is unaffected by most chemicals at common temperatures and conditions and is, therefore, often used to make equipment to handle chemicals.

Touche Chuck, however, I think that you are correct only when it comes to certain alloys where the addition of another metal changes the chemical makup of the ti thus affecting the corrosion resistance. And while it may react to certain environments (including AIR) it remains a metal that will not melt when you soak it in any acid. Please correct me if you have experienced otherwise, I am only going from my own experience and I have not experienced EVERYTHING

I'm not sure if this is intirely correct, but from several sources including my own experince, the oxide that you refer to is some form of chrystalin skin that is apparent in all conditions, even when the metal is scratched. It is a very strange metal, but rust, I do not believe that to be entirely accurate. I did not mean to imply that Ti does not react to heat, only that Ti is chemically inert. But the neat thing about it is that it is evident even in certain mixtures of Ti-nitride coatings as well. I owned a first production Ti-nitride Spyderco Police model. for years it was put to use before I noticed some peculiar characteristics about the coating, and a rumor that Spyderco was unable to duplicate the formula. My particular knife had been a daily user and aquired some sctraches that went through the coating, within a couple of weeks they were gone! Aparently the coating was able to blend and move (if ever so slightly) over the metal and fill cracks were the coating had been scratched off. It did not stain or come off on any of my clothing or skin for that matter, and I have several witnesses who where just as baffled as I about the event and we began to call the coating "Organic" Anyway I thought that was something special and anyone interested in knives would think so too.
