Anyone ever use liquid gun blue(Birchwood Casey) to force a patina on their Fiddleback or other O1 steel knife? I'm wondering if I'd get a similar look to the Blueback Fiddlebacks. I've forced a patina on 2 O1 blind horse knives with great results from lemon juice and some brown mustard for tiger striping, but I'm looking for something a little more subtle now and I love the way the Bluebacks look.
 
I have used Brownells Oxpho-Blue on my carry knife. It's not as fluid of color but does add some rust prevention. In hindsight I'd have done a better prep and done several lighter coats. Any oil on the knife will lead to it not taking color. Mainly around the scales.

Thank for the tip. I think I'll clean the blade with alcohol first and experiment with multiple light coats
 
We use Birchwood Casey cold blue gel to get the Blueback's. Wash the knife thoroughly. If it has a wood handle this might raise the grain, which would need re-sanding. Get it on your gloves and drag your goopey fingers edge to spine. Leave it on 15 minutes then rinse it thoroughly in warm water. Get a toothbrush, drench the knife and toothbrush with windex with amonia. Wash the blade thoroughly and use the toothbrush to be sure to get off any goop in tight spots. C'est la.
 
Nice! Thanks for the official Blueback method!

@abrasion - Thanks for the link, those are some nice patina jobs on the Beckers! I really like how he sanded along the grind lines to define them!

Cool. Thanks for the peek behind the curtain.
 
My Very First Fiddleback was this Blueback Asp. The pics don't do it justice! I love the spalting but Andy's blueing is just awesome!
