The invention of the ViceGrip pliers was by US citizen William Petersen. Today the original company is part of Irwin Tool. After the twenty years of protection by the patent other manufacturers started producing similar pliers. For instance in Spain there is GripOn. In Germany, excellent grip pliers are produced by Bollmann based in Remscheid. Over the years the firm has added many special versions for to name a few: welding and car repair uses. Last year they came with a new hand tool that is the combination of a grip pliers and a combination pliers. With these pliers you can perform actions that are similar to a combination pliers (cutting, holding, turning) and have much more fixation with the grip feature.
