A fastener-driving tool is provided and includes a housing and a workpiece-contacting element movably connected to the housing, where the workpiece-contacting element is movable between a rest position and an activated position. A trigger is movably connected to the housing such that the trigger is movable between a rest position and an activated position. The tool further includes an actuation lever movably connected to the trigger and movable between a rest position and an activated position. A damper mechanism is associated with the actuation lever and is configured to control a rate of movement of the actuation lever between the activated position and the rest position.

1. A fastener-driving tool including a trigger control mechanism, said tool comprising: a housing;a workpiece-contacting element movably connected to said housing, said workpiece-contacting element being movable between a rest position and an activated position;a trigger movably connected to said housing, said trigger being movable between a rest position and an activated position;an actuation lever movably connected to said trigger, said actuation lever being movable between a rest position and an activated position; anda damper mechanism associated with said actuation lever and configured to, following an actuation of the tool in a sequential actuation mode, control a rate of movement of said actuation lever from said activated position to said rest position such that the tool is in a contact actuation mode at least part of the time the actuation lever is moving from the activated position to the rest position. 2. The tool of claim 1, wherein said damper mechanism includes a damper housing and a damper removably connected to said damper housing. 3. The tool of claim 2, wherein said actuation lever defines a groove and said damper housing includes a protruding locking member that matingly engages said groove for inhibiting movement of said damper relative to said actuation lever. 4. The tool of claim 2, further comprising a damping fluid between said damper and said damper housing. 5. The tool of claim 4, wherein said damping fluid is a silicone fluid. 6. The tool of claim 2, further comprising a fluid space between an inner diameter of said damper housing and an outer diameter of said damper and a damper fluid in said fluid space, wherein a volume of said damper fluid in said fluid space is based on the difference between said inner diameter of said damper housing and said outer diameter of said damper. 7. The tool of claim 6, wherein said volume of said damping fluid in said fluid space directly controls the movement of said actuation lever such that as said volume of said damping fluid increases, said rate of movement of said actuation lever decreases. 8. The tool of claim 2, wherein said rate of movement of said actuation lever is controlled by a friction coefficient between said damper housing and said damper. 9. The tool of claim 2, wherein said rate of movement of said actuation lever is pneumatically controlled by air introduced between said damper housing and said damper. 10. The tool of claim 2, wherein said damper housing includes at least one protrusion and said actuation lever includes at least one recess, said at least one protrusion being configured to matingly engage said at least one recess for inhibiting movement of said actuation lever relative to said damper housing. 11. The tool of claim 1, further comprising a bias member associated with said actuation lever and configured to bias said actuation lever to said rest position. 12. A fastener-driving tool including a trigger control mechanism, said tool comprising: a housing;a workpiece-contacting element movably connected to said housing, said workpiece-contacting element being movable between a rest position and an activated position;a trigger movably connected to said housing, said trigger being movable between a rest position and an activated position;an actuation lever movably connected to said trigger;a damper mechanism associated with said actuation lever and configured to control a rate of movement of said actuation lever; anda control valve including an actuating pin, said actuating pin being movable between a rest position and an activated position,wherein following an actuation of the tool in a sequential actuation mode when said trigger is in said activated position, said damper mechanism controls said actuation lever to move from a position adjacent to said actuating pin to a rest position in a pre-determined period of time, wherein the tool is in a contact actuation mode during the pre-determined period of time such that the tool is actuatable via said workpiece-contacting element contacting a workpiece and moving to said activated position causing said actuating pin to move to said activated position during said pre-determined period of time. 13. The tool of claim 12, further comprising a biasing member associated with said actuation lever, said biasing member configured to bias said actuation lever in a direction away from said actuating pin. 14. A fastener-driving tool including a trigger control mechanism, said tool comprising: a housing;a workpiece-contacting element movably connected to said housing, said workpiece-contacting element being movable between a rest position and an activated position;a trigger movably connected to said housing, said trigger being movable between a rest position and an activated position;an actuation lever movably connected to said trigger, said actuation lever defining a groove and being movable between a rest position and an activated position; anda damper mechanism associated with said actuation lever and configured to control a rate of movement of said actuation lever between said activated position and said rest position, the damper mechanism including a damper housing and a damper removably connected to said damper housing, the damper housing including a protruding locking member that matingly engages the groove to inhibit movement of the damper relative to the actuation lever.
