I think everyone should have a pair of these. At first glance they look like something only a plumber or heavy machinery mechanic would need, but you'll be amazed at what you use them for. I call them my "persuaders". I'm short and don't have much arm strength so they're infinitely useful when working with my five old machines. I've used them for everything from opening a stuck oil filler cap to reshaping bent spring clips. They have amazing dexterity and precision for something so huge, and I'm inclined to think they function like an elephant's trunk: capable of plucking a single blade of grass. Channellock continues to produce consistently impressive products despite their modest prices. I love these pliers!
