I'm sure it is somewhere. But my searching turns
up nothing.


I want to make a black blade satin.

It is the mid 90s coating.

What chemical works to remove it?
 
From a number of years ago, this 710D2 had it's coating removed. Used liquid Brasso and 220 through 600 grit wet/dry sanding sponges. Also wore a 3M respirator during the process. The results were really good but very labor intensive. Problem is the blades themselves are given a rough texture at the factory and all of that had to be sanded down. The coating failed, but a lot of it was still bonded onto the blade.

Yours came out NICE.

So far it looks like Elbow grease will make it go away.

But I know someone out there might of tried a chemical stripper.

But which one?
 
I've got a 710M2HS that I want to remove the coating on but I don't think I want to polish it to the point you did jkarp. I thought I'd just go done to the rough factory texture you mentioned using steel wool and hope it would look something like stone wash. What do you think? Would it look terrible? How about the laser markings? Can you leave them or does that look worse? Thanks in advance for your thoughts jkarp.
 
I dont know if it will work for a knife blade, but a buddy of mine used simple vinegar to remove the black coating on his sig sauer pistol barreljust let it soak for about 1/2 hour and the coating came right off
 
I stripped a Busse with paint stripper, a plastic putty knife, and some Scotch-Brite pads.
 
Citrustrip or whatever, keep it off your skin, takes about 3-10 seconds to start feeling it burn. Wear gloves and face shield or good goggles. For sanding, you NEED a hard backing if you want to keep the grind lines crisp. You also need a way to clamp down and support the blade as you sand. There is a maker here who has videos on sanding blades, Nick Wheeler. Watch his videos copy what he does as much as possible.

This might help.

-Just scraped, no sanding.

I will be trying aviation stripper when it comes back
from benchmade.
Getting 're centered and a general go over.

Soda blasting looks very promising.

As for vinegar ?Can't hurt to try.
Scraping it off? 'll try that too.
 
jpm2's M2 blades looks pretty good. Think I'll give that a shot. Can't look any worse than it does now.
 
I used sharp rat2 and small opinel blades to scrape. Both were soft enough not to scratch the m2.
 
The finish depends on how much time you put into it. To remove the texture was a long process. Next time I'll just leave the blade as it is. The coating on the 710BK protects down to the micro level, but you'll never rid yourself of it completely. As to the etching, the laser machine cuts pretty deep. The script on my knife never went away completely.

I used a real Copper penny.
Scrapped off incredible easy. My thumb nail was even removing it.

And yes. You are right. It sticks pretty good. But I like the new look.

Now it looks like Black case hardening.

My biggest issues have been resolved with the paint gone.

No more scratches from cutting paper, cardboard.
Subtle looks.
 
Try scraping it off with a razor blade. Hold the razor blade 90 degrees to the surface and push on the lower middle of the razor blade with your thumbs. If you have ever used a scraper on wood it is the same technique. It is easy to do, but hard to explain with text.
