For the most part, black oxide is a bit more rare than the SS counterparts I am not sure about numbers produced though, just going by what I see That Blast is way more rare than a stainless steel one as well as those PSTs
While looking up some stuff in my drawyer I found some older black MTs in their boxes that I have totally forgotten... (one clue that I have too many...) HI There You say you may have too many ??How can you have too many when you cannot have enough in the first place ? Very nice tools If in fact you do have too many , I happily and gratefully accept donations of excess . Free to a good home aye ?
These are all black oxide.
