Reciprocating tool

A power tool comprising:

• a housing having a handle configured to be grasped by a user;
• a motor supported by the housing and defining a motor axis;
• a driving gear rotated by the motor about the motor axis;
• a driven gear defining a rotation axis that is parallel to the motor axis, the driven gear engaging the driving gear to be rotated by the driving gear about the rotation axis;
• a crankshaft coupled to and rotatable with the driven gear;
• a counterweight having a first yoke coupled to the driven gear to translate rotation of the driven gear into reciprocating motion of the counterweight;
• and
• a spindle having a second yoke coupled to the crankshaft to translate rotation of the driven gear into reciprocating motion of the spindle,
• wherein the counterweight and the spindle reciprocate opposite one another, and
• wherein the counterweight at least partially surrounds the spindle.
