to the OP
welcome to BF fellow prepper
here is what you should consider:
if SHTF a survival blade will come much more handy than offensive blade
if SHTF a it is not likely that you will be moving around spec-op super stealth style & kill people
if SHTF zombies do not care if your knife is coated
if SHTF your knife will be used mostly to process game. wood, and cut stuff
if SHTF Bark River Bravo 1 or 1.5 (in your case will be a very nice option) it will excel at cutting stuff, processing game, shelter building, wood prep and it can be used as a defensive weapon
Bark River Bravo has a satin finish but I do not see it as disadvantage
here is what you should consider about coated blades
pros:
provide protection from corrosion (you can get Bravo in stainless steel or 3v(which is fairly corrosion resistant))
makes the knife less reflective (but unless you plan to go on commando spec op killing spree you do not need it)
cons:
majority of coatings (ie baked on epoxy) will make it impossible to throw off sparks of the fero road (a huge disadvantage in SHTF scenario)
majority of coatings (ie rough ones) will diminish knife slicing ability (will suck at game and food prep)
adds in weight
comes off easily and exposes unpolished surface full of micro pits that facilitate faster rusting
