You always see these black chrome vanadium socket sets being advertised as "impact sockets" but are they really? The black color is meant to make you think that (but I think that's a gimmick because the color is only surface thick), I know but is the real deal the chrome moly socket sets and if so, are they good for everyday use too? Do they last longer? How much stronger are they?
I saw some chrome moly socket sets at autozone today and they really look cool and feel very good. They say they are impact sockets and I believe it. Where do you get your impact sockets from? Are they chrome moly?
