HEllo there,

Something strange is happening with my subcom blade, its creating a lot of brown spots on it, i tried to whash but it wont come out, i dont even use it, i dont know what is going on, anyone had the same issue?
 
It sounds like rust. if you put it in the sheath while it was damp, that could do it, but the 440C it's made of is not particularly prone to rust.

Try to clean it off by light rubbing, and oil it to see if this stops the spread.

Aloha lio,

Man, ya really got it in for me, eh? First the lock failure video and now these "brown spots" on a knife ya don't USE!:rolleyes:

*kidding*.

Anyway, yes, it is corrosion spots, or "freckles" as they are sometimes called. I have knives that are bead blasted that I have not used, and I have to check on them frequently for "freckles". A good wiping with Tuf-Cloth will prevent anything further from happening to it.

Sorry about the rust...

God bless:cool:
 
Daywalker,

Nothing against you hehheh, i really love that knife, thas why im so worried about it, i`ve been edc it for the last 3 weeks and i`ve never put it on work, the only thing i did was whash the blade with soap and did not dry, maybe is that the reason?
 
What reason did you have for washing a knife with soap and water. . .and not drying it?

Just wondering.

Mmmmm...jelly biscuit! I'm gettin' hungry.:D You've got to keep in mind that AUS-8 has a good amount of carbon in it and isn't as high in chromium as, say, a 440 series blade. Those attributes, combined with the bead blast finish, mean it will require a modicum of care in order to avoid rust. If you live in a humid environment, then rust is even more of a problem. As Daywalker suggested, a quick wipedown with a Tuf Cloth (silicone impregnated, I believe) after use or handling is about all you need to do.:cool:


edit: actually, not silicone. My mistake. Here it is, if you're not familiar with the Tuf Cloth: http://www.1sks.com/store/sentry-solutions-tuf-cloth-info.html
 
one thing that i forgot to mention , that happened in just one day, when i went to bed the blade was fine, when i woke up the blade was with those spots, my question is, can those "freckles" apears in last of 24 hours? today i will put some pictures, sorry about the late.
 
Aloha lio,

Well...try living where I do and see what happens to pretty much anything bead blasted!:D Rust can happen in a few hours here...no kidding.

That being said, I *try* to wipe down my bead blasted knives with a silicone cloth OR if it'll be stored for awhile, then I use a Marine Grade Tuf-Cloth.

THAT being said, remember that everyone's body chemistry is different and some have a more "freckle effect" on steel.:p

You are experiencing nothing out of the ordinary...and man, ya shoulda seen some of the ol' 420J2 versions! Whoa!!!:eek:

God bless:cool:
 
Hi, you ever heard of an abrasive cream called "iosso"? I had freckles on my Subcom and a wipe of that with an old t-shirt sleeve cured it.
 
Get some Flitz and give it a *light* polish. It will protect it. Don't polish too much though or you will make it shiny!
 
My Biscuit is of Irish descent as it is just loaded with freckles, but that is my fault for not properly caring for a steel that can rust easier than some.

Looking forward to the Strawberry Biscuit!
 
I've had rust stains appear on ATS-34 blades from just thumbing it open a few times and carrying it, clipped to a pocket, after a long hot summer day.

Lio, if you're in a hot and humid country, you can get stains on a "stainless" blade like AUS-8, especially if it's beadblasted, just by carrying it around and leaving your finger oil/sweat on it.

I tried coating it with all sorts of things - Marine Tuff-Cloth, Renaissance Wax, Militec-1 -- nothing.

I ended up using a thick coat of MDLabs' XF-7, which did the job.

Something else you can try that I did to my Kershaw Leek is polish the blade with high grit sandpaper. My Leek would rust easily in my pocket because I sweat a lot, being outside and active rather often. I polished it with 1200 grit sandpaper to remove the beadblast finish and it's much harder to get rust to appear on the blade surface. I use my pocket knives around food a lot so I don't like putting silicone, oils etc on the blade, even if it does mean a little moe maintenance and care on my part.
 
It happened to me with some knives (not with the Biscuit). The tiny spots went out after I oiled the blade, left it for a few minutes and then wiped it with a piece of cloth (granny needs new underwear :eek: )
