I had the same experence as Yak a few months back. I broke my dads Craftsman "Vice Grip" knock off. When I took it in to change it out they tried to give me on that looked like a RoBo grip with the stacked sheet metal insted of the solid steel like the one I broke. They had the solid steel one, but they put some plastic handles on it and called it Proffessional Grade.... but the one I had was from the 80s before there was Proffessional Grade. I had to explain to the clerk that I wasn't going to leave unless the plyers I was leaving with were the same design as the ones I broke.
