The Hammer design is one of the first two piece designs. The two parts are the can and the stem. They are “welded” together. A clean weld is critical for strength. Cheap and poorly made Import two piece pipes often break at this weld. For this reason alone, the cost of American made Glass Hammers is worth it. Hammers are popular for several reasons. One of the best aspects is the fit and feel in the hand. The “can” sits nicely in the hand which makes it more comfortable to hold and easier to pass to your friend. The other important benefit is that the can acts an ash collector and thus keeps some debris from pulling through.
