From the storage case down to the smallest bit, this is an AWESOME set!! Snap-On tools are expensive, but you get what you pay for nowadays. The Brownells set (which is probably made by the same company that makes this for Snap-On) is the only set I can think of that is in a league with this set. This SO set has all the pieces you need for basic Torx,flat head, and Phillips head screws. And a couple others too. The interchangeable parts are a huge plus between the handles and the shanks. Will make if all justified in me being crazy about keeping this set clean and all together. All the surfaces fit together nicely and the mechanism is smooth as silk. I have many Snap-On, Wright, Craftsman and other American made screwdrivers , this set is definitely top of the line and one that I’ll hand down to my children and grandchildren.
