Went into OSH yesterday and they had these rachet sockets with a new pattern they called slotted. About 1/8" wide bars running down the throat. The same socket fits hex and up to 50% rounded hex, square, 12 point and star pattern heads. I thought it may be on the weak side but then again it looked like it would make the same surface contact as a 12 point socket on a hex head. Wondered if anyone had used or know of a test of this new type of socket. I wouldn't put it up against a 6 point but they might be as good as a 12 point socket.
