Actaully,if I have heard correctly,Carbon 5 is not a blade steel, but just the advertising name Cold Steel used to describe their carbon steel, which could have been many steels at one time or another. The blades themselves were made by Camillus (maybe others) and was the same steel used in the Becker line before Camillus went out of business. That would make Carbon 5 the same as 0176. Cold Steel does not make their own knives but contracts out to others now in Japan, and China. The SK-5 is also a good steel according to others.
I agree with all of the above. I only said carbon V because it is more known than 1076.
I have heard people here say that SK-5 is to 1080 what 1095 is to 1076. Same carbon content with vanadium and chromium added
