The upper housing  802 , the lower housing  804  or both may include a second handle  818   b  that provides leverage to turn the first handle  818   a . In operation, the first handle  818   a  and second handle  818   b  are squeezed together to rotate the adaptor gear  814  that rotates the set of gears  808  which in turn rotates the ratchet adaptor gear  816  that receives the drive adaptor  820 . In addition, the ratchet adaptor gear  816  includes an insert aperture  824  configured to fit the drive adaptor  820 . Other embodiments, include ratchet adaptor gear  816  may include an insert aperture  824  configured to fit a spline drive, a square bit, a polygonal bit and so forth (not shown). 
         [0043]    The set of gears  808  can have a variety of configurations (increased ratio, decreased ratio, strength, size, etc.) depending on the space constraints and the specific application. For example, gear configurations may be used to provide an increase or a decrease in the drive ratio. A combination of gear teeth and gear arrangements may be used to allow the alteration of both torque and speed between the input and output values. For example, a combination of 8-tooth gears  8 A,  8 B and  8 C 
         [0000]    and 40-tooth gears  40 A,  40 B and  40 C allow a dramatic reduction in gearing ratios. For example, the final drive ratio between 8-tooth gear  8 A and 40-tooth gear  40 A is 125:1. This is achieved through the combination of the 8-tooth gear  8 A driving the 40-tooth gear  40 B at a  5 : 1  ratio and 8-tooth gear  8 B driving the 40-tooth gear  40 C and the 8-tooth gear  8 C which drives the 40-tooth gear  40 A to allow 100 rpm input to be converted to 0.8 rpm output (the converse may also be accomplished to drive a 0.8 rpm input to be converted to a 100 rpm output). Another example, includes a 40-tooth drive gear  40 A is connected to a 8-tooth gear  8 A to form a 1:5 ratio that turns 5 rpm per 1 rpm of the drive gear  40 A. A 20-tooth gear  20 A and a 40-tooth drive gear  40 B are connected to the 40-tooth gear  40 A to form a 1:2 and 1:1.66 ratio to turn 2 rpm and 1.66 rpm per 1 rpm of the drive gear, respectively.
