Knife Patinas?

from a quick search .. possibly gun bluing stuff. stainless takes a bit more Oomph to get a patina on it.

ahh.. that was another guess.. a knife forum might be a better place to ask like Bladeforums

I've found its etching acid from radio shack that most are using.
30 minutes in the solution, then 30 minutes in a rock tumbler.
Obviously, you'll be resharpening your knife.
I'm wondering if there's any negative effect on the pivot points and locking edges….perhaps they can be taped off.

As he said, Bladeforums… this post has a recommendation exactly for your 154CM

No mention of a tumbler. It seems the acid and light steel wool is sufficient to remove the polish, and then an acid/vinegar combo gives you colour. I like the use of mustard. I make my own. Heck, didn't I give you some for Christmas? I meant to.

Is this an aftermarket blade treatment/patina? The Benchmade Griptillian by Doug Ritter comes already stonewashed. http://www.dougritter.com/dr_rsk_mk1.htm

Yep, thst BM finish is stonewashed. Its done in a tumbler with abrasives.

I never thought I'd buy a Griptilian until I saw the one in the OP with micarta scales.

(sigh)

Well I guess you can't own too many Benchmades.
