    The design of the locking mechanism is such that it will actually work with other brands of sockets (at least, what I have around, like SK). I've encountered other brands that don't work with different sockets, like Wera, which are also very difficult to operate. The Stahlwille operates easily.

    I have grown to love stahlwille tools and their QR extensions are the best. Their tool steel and chrome are very durable.
