new(to me) tools

Was in Lowe's and the Kobalt tools were next to the checkout counter I was using. There was a type of rachet set I hadn't seen. The sockets had 12point(I think) teeth cut on the outside of the socket which fit into a corresponding hole in the center of the rachet. The top of each socket had a round hole in it corresponding to the diameter of the bolt the nut that size socket would fit on. Idea is that you can drive nuts down a long threaded rod with the ratchet without having to use a deepwell socket or switch to a open end wrench.

I also was in a local tool shop that sells all top quality tools. (those in upper SC may be familar with Mac Fullbright Tools in Spartanburg, SC) Anyway, he had on the counter a new type of SK rachet set. The sockets were cut to fit spline fastners. Each socket will also fit Torx , square, and regular hex fastners in the appropriate size. Some of you guys may be familar with this but it was new to me.
BTW, I've always considered SK tools to be near the top in quality. They are priced accordingly.
