KNIPEX Tools 00 20 06 US2, Pliers Wrench 3pc Set

These are quite expensive, but if you can stomach the price, they are GREAT. You will never want to use a crescent wrench again.The 10:1 levering on the jaws makes these absolutely steady when used on hexagonal or square nuts or bolt heads. You can achieve nearly the same convenience as a ratchet by relaxing your grip on the backswing - it has enough play to slide over the corners until you squeeze it back against the parallel sides. It's not at all hard to use this way without damaging the fasteners, which I was pleased to find out.This means instead of fumbling around for the right wrench or socket, you can just use this one tool on nearly any size fastener. The middle size tool covers most of what you want to do, but the large size and the small size are handy - for holding the other end of the bolt, or for the biggest or smallest fasteners.It can grip TIGHTLY when used to hold a bar or sheet of something, too, although since the jaws are smooth it's not a total replacement for pliers. It IS a total replacement and a huge improvement over the familiar crescent wrench, though.Can't say enough about how nice this tool is to use. If you like to spoil yourself or use tools a lot, it's worth the cost. Get only the middle size if you want to save money.
