This 3/4" drive socket set is a combination of Blackhawk and S/K tools that dates back to the 1960's. The ratchet and break bar are unique in that the end of the handle is drilled to accept the extension bar that is included with the set to give you more leverage. There are fifteen sockets ranging in size from 7/8" up to 2" along with three extensions, two of which are drilled on the end to accept the extension for more leverage along with the t-handle and the ratcheting attachment for use with the break bar. You don't find socket sets with all there features anymore.
