i have a knife that has a black coating that is worn terribly....i would like to remove it all and have just bare metal

is there a liquid for this....or would i use a dremel like tool?

if a dremel, could you give me a model (maybe Sear's) that would work...also which attachment would i use on the dremel


you can see that i've never used a dremel before!! :)
 
I think that there may be a thread on this already. Maybe do a search???


I thought that I read that you cvan use easy-off oven cleaner to do the job.
I never tried to do this, but maybe the search can shed some light on this.....

A friend of mine used scotchbrite on a belt sander & it worked great for him. I was too much of a chicken to try it :D



I just tried to do a search & for something new & diff, it wouldn't work for me :grumpy: So much for being a Gold Member! :rolleyes:
 
Some options:

Assuming the coating is epoxy, you can use thinner or acetone (as in nail polish remover.)

Use a softer steel than the knife (or even sharpen some brass or aluminum) and scrape off as much as you can. Since the epoxy powder coats are usually "baked" on, you can heat the knife up a little to soften the coating before you start scraping. I wouldn't go above 225 or so, to avoid annealing your blade or loosening glue joints or setting your handle material on fire. Come to think of it, don't heat the knife at all. :footinmou

Use a bead blaster, or a belt grinder/sander and be prepared to go through quite a few belts.

Be a real he-man type and hand rub that crap offa there with a shoe-shine rag and some toothpaste.

Good luck. ;)

If it is a folder you are going towant to disassemble it
If the coating is some manner of powder coat try paint stripper or soak in a solvent like acetone. Brake fluid will also probably destroy the powder coat. If you have one of those electric heat guns give that a try on the low setting.

If it is a metalic coating like Titanium nitride (TiN), You have some work ahead of you. TiN is an Anti wear coating commonly used on deep draw stamping dies to prevent galling. It is probably around 20 rockwell points harder than the blade steel underneath it. You are going to wet sand till your fingers are numb and then wet sand some more. EEEEEEEEEEK!

This is what the pros use to take off epoxy from the inside of silos, (that posses was developed by my uncle mike), I'm sure it will take off any such coating.

This **** will eat through plastic or any such thing like it was butter though so take off the handle. Also, the stuff is very very very flammable (though all the guys used to smoke inside of them anyways). It might also be a mild carcinogen. :)

Have fun.

PS: That crap makes Ammonium Nitrate Fertilizer look like lemon juice when it comes to bombs. ;)

This can be a frustrating experience. But if you have access to a Napa Auto Parts store buy this:

"TECnique" Professioal Car Care Products" Professional Detailers Line Paint Stripper. Napa/Martin Senour Paints.

After trying a dozen different products, including heavy duty strippers (courtesy of my pal at the hardware store) I found that none had any real effect on my black epoxy Cold Steel Recon Scout. Same with sanding, steel wool. etc. etc. That CS coating is tough.

This TECnique stripper took it off without batting an eye. I just masked everything well, except the brass guard, which I wanted to strip and polish along with the blade. Sprayed it on and it came off in sheets. good luck!

Edited to add:The upper left hand corner of the front label has a number 7229
 
I remember reading about someone that kept stabbing the blade into clay (pottery clay, not oil based). Makes sense to me. Be aware though, you will have to resharpen your knife. I removed the coating on a folder (not sure what the coating was), and I just used extra-fine grit sand paper. Took some work, but it looked great in the end!
 
Paint stripper has worked well for me on epoxy coatings. MEK, as described by pest-i-lence may work, depending. It has little effect on some powder coats, eats right through others. Doubt either would have much effect on stuff like TiNi.
I suppose you could have the blade bead blasted, if nothing else works, and have a bead blast finish, or sand it by hand afterwards...

How did this work out for you? I am early stages thinking about doing it to a Ka-bar Mules folder I picked up used.

The black epoxy coating is partially worn off and I can't decide yet if it's "sick" the way it is or I should strip it.

You revived an 18 year old thread, to reply to a person that hasn't been online for 12 years?

Seriously???? :rolleyes:
