When you think of wrenches, you probably think of standard box or adjustable wrenches, with maybe an occasional pipe wrench or monkey wrench thrown in. What a lot of people don't know is that a strap wrench can be a very helpful way to get some added leverage without having to spend a lot of extra time at the gym lifting dumb bells. Strap wrenches are especially helpful when you need to move a smooth round object like a pipe. The strap can grip the outer edge of the pipe and the solid part of the wrench will give it a good bite so that you can grip and turn with ease.
There are a few types of strap wrenches, each used for very different purposes. The most common type of strap wrench is your basic plumber's strap wrench. This tool consists of a strap attached to a handle with a curved tip. The idea is that when you cinch up the strap, the curve will hug the contours of the pipe. Another type of strap wrench is an oil filter wrench. This is primarily used by auto mechanics and has a much thinner strap. Finally, the chain whip is yet another type of strap wrench. You probably won't be familiar with this style of strap wrench unless you are a cyclist; it is used to loosen and tighten sprockets on a bicycle.
