"I have been using the Vise-Grip locking tools for years and find them to be a tough tool of superior quality. Everyone I own has paid for itself many times over thanks to their rugged construction and wide variety of applications. No, I don't work for IRWIN, nor ever have. I just believe they make a better product than all the other locking plier look-a-likes. The "original" vice-grip is the only locking plier brand for me. Thanks IRWIN."
