The Right wrench
We have all heard the expression that it takes the right kind of tool to do the job right. Also many people have tried to perform a particular job without the correct tool and know how difficult it can be. Over time many wrenches have been developed to assist craftsmen at their various trades. For the plumber of course there is the pipe wrench.
With it's serrated jaws enabling it to grab a hold of a round metal pipe, and its many options in terms of sizes of jaws and handle length; it is indispensable to the practitioner of this trade. For the mechanic, electrician, or everyday handyman the needle nose pliers are an excellent wrench for grabbing wires or anything in a narrow space. The mechanic also requires a wide variety of wrenches for different sizes of bolts and nuts.
Two very standard wrenches that you will find in every mechanic's toolbox are the open end wrench and its cousin the box wrench. The open end wrench has an open jaw face and the box wrench has a closed jaw face. These wrenches come in fractional sizes to fit every available nut and bolt.
Another very helpful wrench that provides an alternative to the open end and box wrenches is the ratchet wrench. It is so called for it's ability, by virtue of an internal mechanism, to ratchet back and forth without removing the tool from the nut or bolt. Ratchet wrenches come in different sizes based on their attaching stem. This stem attaches to an assortment of different sockets made to fit a wide variety of bolts and nuts.
