I have Craftsman 6pt. also. They are great for the money, I don't use them all too often but they are some of those tools that when you need them, you need them!
I bought this set on epay. I figured that when I need 6 point, I probably am working with a tough hard to get to nut, so these are longer. The tolerances are so close that I have to sometimes tap them onto a nut with a little rust.
The 6 pts look pretty, but what exactly is their advantage over 12 pts?
I don't mean 6 pt V 12 pt, I know their difference. But is there a specific use for 6 pt wrenches? It just seems like it's hard to turn in tight spots.
