A jigsaw may include a housing, a control member, a shoe member and a keel. The housing contains a motor and include a handle. The control member is moveable relative to the housing between at least a first position that implements a curve-cutting mode and a second position that implements a straight-cutting mode. The shoe member is connected to the housing and includes a bottom surface facing away from the housing. The keel is operable in a deployed configuration in which the keel protrudes through the bottom surface of the shoe member and a stowed configuration in which the keel does not protrude through the bottom surface of the shoe member. Relative motion between the shoe and the keel allows the keel to be in the deployed configuration when the control member is in the second position and the stowed configuration when the control member is in the first position.

1. A jigsaw comprising: a housing containing a motor and including a handle; a control member supported by the housing and moveable between at least a first position that defines a first mode and a second position that defines a second mode; a shoe member connected to the housing and including a bottom surface facing away from the housing; and a keel assembly movably connected to the housing and including a keel member, the keel assembly being connected to the control member by a mechanism that moves the keel assembly relative to the housing and the shoe member into a deployed configuration in which the keel member protrudes through the bottom surface of the shoe member in response to movement of the control member into the second position, and the mechanism moves the keel assembly relative to the housing and the shoe member into a stowed configuration in which the keel member does not protrude through the bottom surface of the shoe member in response to movement of the control member into the first position. 2. The jigsaw of claim 1, wherein the mechanism is coupled to the shoe member to pivot the shoe member relative to the housing and the keel member between an extended position and a retracted position in response to the control member moving between the first and second positions, respectively. 3. The jigsaw of claim 1, further comprising a reciprocating shaft movably supported in the housing and driven by the motor, the reciprocating shaft is operable to move the cutting blade at a reciprocation speed and at a magnitude of orbital motion when the motor is receiving electrical power, and the control member controls the magnitude of the orbital motion and the reciprocation speed. 4. The jigsaw of claim 1, wherein the control member includes a handle accessible from an exterior of the housing that is rotatable between at least the first position and the second position. 5. The jigsaw of claim 1, wherein the control member includes a pinion shaft rotatably supported by the housing and engaging a rack member, wherein rotation of the pinion shaft is converted to linear movement of the rack member to actuate the relative movement of the keel and the shoe member. 6. The jigsaw of claim 1, wherein the mechanism includes a cam member that connects the keel assembly and the shoe member so that movement of the keel assembly produces a countermotion in the shoe member. 7. The jigsaw of claim 6, wherein the cam member is connected for rotation relative to the housing, the shoe member, and the keel member, wherein the shoe member includes a connector portion and a pin member, the pin member extends from the connector portion and extends through a channel formed in the cam member, the pin member is operable to travel in the channel of the cam member when the control member is moved between the first position and the second position. 8. The jigsaw of claim 1, wherein the shoe member is pivotable relative to the housing and the keel member between an extended position and a retracted position, and wherein the shoe member includes a magnetic member and the housing includes a clip member, the magnetic member is releaseably connected to the clip member when the shoe member is in the retracted position. 9. The jigsaw of claim 1, wherein the keel member is connected to a rack member with an elastic clip and an elastic member is disposed between a motor block in the housing and the rack member, the elastic member is configured to exert a force on the rack member in a direction that is transverse to a direction by which the elastic clip is configured to exert a force on the keel member. 10. The jigsaw of claim 1 further comprising a cutting blade drivingly engaged by the motor and wherein the first mode is a curve-cutting mode and the second mode is a straight-cutting mode. 11. A jigsaw comprising: a housing containing a motor activated by a trigger assembly; a control member movably supported by the housing between at least a first position that defines a first mode and a second position that defines a second mode; a keel connected to the housing; and a shoe member pivotally connected to the housing and connected to the control member by a mechanism, the mechanism moving the shoe member relative to the housing and the keel between an extended position and a retracted position in response to movement of the control member between the first and second positions, the shoe member including a bottom surface facing away from the housing and defining a channel through which the keel extends when the shoe member is in the retracted position, the keel being stowed between the bottom surface and at least a portion of the housing when the shoe member is in the extended position. 12. The jigsaw of claim 11, wherein the control member includes a pinion shaft rotatably supported by the housing and connected to a rack member of the mechanism, wherein movement of the rack member causes the shoe member to move between the extended position and the retracted position. 13. The jigsaw of claim 11, wherein the mechanism includes a cam member that connects the keel and the shoe member so that movement of the control member between the first and second positions causes movement of the keel relative to the housing and the shoe member. 14. The jigsaw of claim 13, wherein the cam member is connected for rotation relative to the housing, the shoe member, and the keel, wherein the shoe member includes a connector portion and a pin member, the pin member extends from the connector portion and extends through a channel formed in the cam member, the pin member is operable to travel in the channel of the cam member when the control member is moved between the first position and the second position. 15. The jigsaw of claim 13 further comprising a reciprocating shaft movably supported in the housing and driven by the motor, the reciprocating shaft is operable to move at a reciprocation speed and at a magnitude of orbital motion when motor is receiving electrical power, and wherein movement of the control member controls the magnitude of the orbital motion and the reciprocation speed. 16. The jigsaw of claim 11 further comprising a cutting blade drivingly engaged by the motor and wherein the first mode is a curve-cutting mode and the second mode is a straight-cutting mode.
