What’s a Jigsaw? Jigsaws are indeed the primary tool used to traditionally create the jigsaw puzzle, and while some historians have claimed otherwise, it is the source of the name (some claim they were called jigsaw puzzles because they resembled something a jigsaw could do). Jigsaws are used for a number of more precise, challenging cutting projects where their vertical nature and flat surface for guiding is very helpful and more precise than a circular saw or hacksaw.
Jigsaws are set up on what is called a “jig”, hence the name, or an adjustable work bench/rig with a flat surface. A circular saw which reciprocates dominates the middle of the area. Wood, metal and other materials are placed onto this flat surface and guided, carefully, by hand. Elaborate artwork can be cut out of wood or metal, precise curves and cuts for complex crafts projects can be achieved, and just an easier general cut of boards, dowels and planks is also possible due to this configuration.
Jigsaws also do exist in a somewhat portable form which isn’t technically an actual jigsaw due to the absence of the jig, but the vertical reciprocating blade has become the component that most qualifies a saw for the name in contemporary terms. Jigsaws can be electric or gas, though electric jigsaws are far, far more common, and actually have been since before the turn of the century.
Jigsaws should be operated by experienced users, as they are obviously a somewhat dangerous, but very helpful and elegant tool indeed.
