I had forgotten about this thread...
It's late, and I'm not home; so I'll recycle an image from another thread

This patina started immediately on receipt of the SwampComp MegaRMD. The green canvas needed to be greener; so I into the dye it went. The vinegar and salt in the mix left a pretty solid band of dark grey patina about 3/4-1" above the scales...So, when the scales were done, I flipped the knife and held it blade down for a few more minutes. Since then, I've used it a bit (hence the dirty scales).
I'll try to get a new picture on my next day off
