is this just for colour or does it help rust proof the blade too?

Nice patina on that hawk.....and the answer to the second strip is complete heart block LoL
How easily does a vinegar patina scratch when using the knife/hawk/whatever you put it on ??
Specifically, here's what I did. Stripped the head a couple weeks ago. Without any other prep, I threw it in a pot of heated white vinegar. Not boiling, but too hot to touch. I left it there for 15 minutes. I was surprised at how dark the patina had gotten over just 15 minutes, but also at the texture. To me, it feels EXACTLY like a good parkerized finish. For no prep, the patina is more uniform than I thought it would be. The greatest differences are in areas of different grinds, such as the inch or two behind the edge and the inch or so behind the poll. While these areas are obviously ground differently, this could also be due to differential heat treating. IDK if CS does this with their hawks. I don't think there's anything you can really do to change the way it takes a patina if this is the case. The only thing I'll do differently next time is to hit it with some brake cleaner before it goes into the pot.
I have one of those old Tramontina "Carbono" Bowies.
They are certainly Diamonds in the rough.Excellent knives.
I got mine for $5 in a pawn shop and rehandled it.
Too bad Tramontina doesn't make those anymore!
Their machetes are still good but all the Tram knives i've see lately are low end stainless steel and kinda....bleah!
CaptInsano nice job on the Trailhawk head!
I just finished stripping and patina-ing a Trailhawk head last week.
I used apple cider vinegar which worked fairly well.
But for some reason the apple cider vinegar worked much better on my Becker Companion blank.
Different grades of steel react differently i guess.
And of course the Trailhawk head was very textured and unpolished versus the fairly well polished Becker.
If i get another Trailhawk i think i'll polish it on a belt sander before patina-ing.
Started looking at some wisdom for FP on some carbon steel knives that I have. But after looking at the axe head, I realized that this is just the thing for some of the tools that I have in the shed. Great post!
I have been messing with patina for a bit.
Vinegar and acids turn carbon grey.
Blood and green onions turn carbon blue.
From my experience, I have snakeskin scale pattern on the back of my misono Swedish steel.
I used mustard mixed with lemon juice and applied (took forever) with toothpick.
Be careful as liquid settles and may not dry in the exact place you drew.
Forgot to add, patina makes my knife very sticky to certain foods (fish for me) so I rub rust eraser every few days.
I love vinegar patinas
They do scratch though, so I still wipe down with mineral oil if I won't be using the knife for a while.
