Aluminum. Paint vs anodizing
I honestly can't distinguish what's the difference with some products.... I've had painted items "chip" so that's a give away, but other items the color fades instead of chipping... Would this indicate Its anodized, or just different paint processes?






What are some common signs of anodizing?

Figured with all the mod snobs, at least 1 person here would have some knowledge to share?

I looked into anodizing vs paint. It seems, from a shallow investigation, that anodizing etches into the surface, therefor, should not chip. There are aluminum specific paints that also etch as in aircraft paints so, they will chip but leave a residual and are very expensive. I am sure there is more to find, but I did not get too deep.

It looks (to me) as though you have an anodized piece, as the color is wearing down on it. But I'm no expert.

So it seems I'm having trouble with searching for Other info\signs.....

I find alot of info on why one is better than the other, and how to "apply" the finish, but nothing much further than that.







Just really curious what signs to look for. It's mentioned alot here for ecigs about bad paint and the such, I'm positive everyone here has seen those mentions. That knife has Ben used daily as my sole work knife for the better part of 2 year. Free floating in an apron pocket with another knife(for prying and scraping), keys, and loose dust\woodchips etc. It being a cheap as chips knife, I wondered if that was paint or anodizing.

+1 details
Just my opinion, but I think it is anodized, and I don't know how to verify that opinion.

Skeeets, It's 100% anodized...looks just like my older, beat up Driptech squonkers. If truth be told, anodizing usually lasts much longer under repeated use, and as far as aluminum goes, it's much tougher than powder coating, which scratches much too easily.

EDIT: I am assuming the knife in the photo is aluminum, correct?

As to "signs" to look for, chipping would definitely mean paint whereas gradual fading from surface wear is indicative of anodized finish. Not that paint won't also fade and wear down. In the above post, you have a 100% definitive answer as to what you have, assuming it is aluminum. But then, I had one and can attest to it as an aluminum frame.

Yes it's aluminum. Surprised a cheap 6$ knife had a decent "color job".

On a side note:
Don't know much about how to apply and which paint, and which methods are the most durable (in the house) with little objects that are undertaken of a heavy use in hands + all the issues that carrying them in pockets etc. mean,
neither about anodising, but I know how to take off anodising extremely easily. ;)

Dip yout object into some sodium hydroxide solution for a couple of minutes (maybe 10). Done!

Very cheap product, you can get it everywhere. While it's declared highly poisonous and pollutive, it's used even in the food industry. (even in households for to take off bitterness of olives for example)

But only if you don't mind bare aluminium, if you don't have sweaty hands etc.




While taking off different kind of paints is a slightly more hassle...
