A mushroom-type hook strap for mechanical fasteners has a series of hooks integrally formed on the strap, with each hook formed by a polygonal shape situated on top of an axis of a single stem, thereby forming a mushroom type hook having a polygonal head portion on the axis of the single stem, with protruding portions in substantially every direction for engaging fabric loops of a loop strap. The first retaining member and the central member define a first pipe receiving region. A nail file is preferably provided on an outside casing of the cartridge. Based upon the relative numerical values representative of the consistency and performance of the golf shots made with a number of different golf clubs, the golfer can select the set of golf clubs which provides the combination of consistency and performance that is best suited for the golfer’s game. The assembling clamp detachably engages the casing and has two second hooking elements.
