I have a stud extractor set thats been sitting in my box for a while that I purchased used somtime ago, I have other sets so never really took the time to look at these, Im wondering if they are really blue point or if somone stuck differnt ones in the box, The only etchings on the sockets themselves are the size-for hand use only-and either a 04 or 05. I was going to sell this set but not unless im sure the sockets are Blue Points which on my other stuff is usually stamped directly on the tool, the case# is s345 anyone else have these or know? THANKS
