Selecting the Right Tool For the Job
Double-Handed Tools
Double-handle tools are used when power tasks are required. They are measured by handle length and grip span.
The grip span is the distance between the thumb and fingers when the tool jaws are open or closed.
Double-handed tools include bolt cutters, pipe wrenches, adjustable tap wrenches, wire rope cutters, and tube benders
Precision tasks: For double-handle tools used for precision tasks, select a tool with a grip span that is no less than 1 inch when fully closed and no more than 3 inches when fully open. See Example
Forceful Exertion: For double-handle tools (plier-like) used for power tasks, select a tool with a grip span that is at least 2 inches when fully closed and no more than 3 1/2 inches when fully open. Consider using a clamp, a grip, or locking pliers when continuous force is required. See Example
Pinching, gripping, cutting:: For double-handled pinching, gripping, or cutting tools, select a tool with handles that are spring-loaded to return the handles to the open position. See Example
