Irwin’s Groovelock line of pliers, a variation on the familiar ChannelLocks used to only have one type of jaw, a V shaped all purpose jaw. This type of jaw is great when the the object you’re trying to grab fits in the V well, but sometimes its not ideal and a straight jaw would grip better. As anyone who’s ever used this type of pliers like has found out the hard way, the teeth in the jaw do a great job gripping onto the object, but can frequently dig in and mar the surface. In these situations a smooth jaw might be a better fit. Irwin has realized this and now offers three different types, their original all-purpose v-jaw, the straight jaw, and the smooth jaw. All three come in a variety of sizes, and they all feature Irwins ‘Magic Button’ which allows you to quickly and easily adjust the size.
