Nice job, good start. That's what mine looks like, I'm going to lightly steel wool it and repeat a couple of more times, steel woolling in between both times. It's either that, or sand it off and try the ferric acid route. I really like the way Scott at Razorback knives gets his with ferric acid.

I don't think you're doing anything wrong, I like it.

PS - It will need to be sharpened when you're done, the edge gets pretty dull doing this.
 
I have been wanting to try this, but can't find out how. I have cold blued a couple of my old Western carbon blades and I really like the way it looks.

well, from just reading the post on patina, i just steel wooled the blade with 0000 and put the mustard on as even as i could get it and let it sit for about 8 hours or until all the mustard turns black........wash it off and steel wool it and start again....................
 
Could you give me a link the post on patina that you refered to?
 
I did this finish on an A2 Bark River Aurora with hot white vinegar. 20 minutes at a time with rag polishing between treatments. When I got it dark enough I polished the entire blade with rawhide and resharpened the blade on a charged leather strop.

I would first use some 400 or 600 grit abrasive paper to make sure there is nothing from the manufacturing to interfere. Then DON'T Touch the blade ,it must be totally clean , no dirt, oil etc !! Try again !
 
ok so am i looking for a solid dark color or should i shoot for the case harding look?...........would the attemp that im doing not offer enuff protection on the metal?
 
One cool thing that you can do with the mustard is to use your finger to make patterns in the mustard. The areas where the mustard is very thin and some of the steel is exposed becomes darker. I made a nice looking tiger stripe on a knife.

My son looked at me kinda' funny the first time he saw me putting on the mustard patina. I think he's getting used to the fact that dad is somewhat odd at times:D

Phosphoric acid on a 0-1 blade gave me a very light pinkish-blue tint to the steel. It's very subtle, but looks nice.

been thru a few mustard cycles and this is what ive got so far........

the blade appears a little darker than it is in the pics, but you get the general idea what it looks like, its comming nicely i think, with the lines and darker areas give it some charicter.

this is fun, not knowing what it will look like after you take the mustard off each time.

i will do another couple cycles later as i need the knife now to take with me hunting........

let me know what you all think.....................
 
I had never heard of this before, but there are a lot of things I don't know :confused: .... This actually looks like fun, and I like the look it gives.
Are there certain steels that take to this better?
 
I like it, too.

You can also do a lower level of patine - just leave the mustard on less time - it is real pretty on a polished bevel.
