I have one of the aforementioned breaker bars - I bought it when Princess was having free shipping on all orders. The bar isn't made in the United States. If I'm not mistaken, it's made in Taiwan. The bar itself is straight. It's quite weighty, but well made. The shaft is roughly as big around as one of the cheaper garden hoses - probably about as big around as a "C" battery. The hand grip is reminiscent of a Kobalt ratchet and the head is a heavy black oxide finish. The swivel is slightly biased to one side, with a lock washer (or similar) providing a bit of tension. A hex head bolt goes through the entire head. The bar held me jumping up and down on it (200 lbs) without bending.
