The reciprocating shaft is located at the front end of the saw and moves back and forth at a high rate of speed, which in turn also moves the blade when it is inserted into the shaft. The blade is held into the shaft by either a set screw located on the side of the shaft or a blade clamp. Inside the main body of the saw is where the actual motor is housed. The motor is either powered by electricity or by battery. The motor connects with a spindle that pushes the reciprocating shaft when you pull the trigger on the saw.
