A multipurpose tool system that can be assembled into multiple configurations by a user. The tool system may comprise a plurality of components, including tool heads, shaft segments, and handle ends. The components of the tool system can be combined in various configurations to provide different functions, at different lengths. Connectors may be utilized to connect the various components of the system using a twist lock mechanism. The connectors may include a tubular sleeve member having a biased locking shaft that interacts with a locking groove.

1. A hand tool comprising: a first tubular sleeve member defining a first socket and a second socket;a first shaft segment having a tip installed into the first socket of the first tubular sleeve member;a second tubular sleeve member defining a first socket;a second shaft segment having a tip installed into the first socket of the second tubular sleeve member;wherein the second tubular sleeve member is configured and dimensioned to be removably inserted into the second socket of the first tubular sleeve member;wherein the second tubular sleeve member is rotatable about a longitudinal axis between a locked position and an unlocked position with respect to the first tubular sleeve member;wherein the first shaft segment and the second shaft segment are positioned end-to-end, without overlapping, by the first and second tubular sleeve members to define a handle assembly; anda tool head connected to the handle assembly. 2. The hand tool of claim 1, further comprising a cam mechanism operable to guide the second tubular sleeve member between the locked position and the unlocked position. 3. The hand tool of claim 2, wherein the cam mechanism comprises a cam surface formed in the first tubular sleeve member and a pin extending from the second tubular sleeve member. 4. The hand tool of claim 3, wherein the pin extends perpendicularly to the longitudinal axis. 5. The hand tool of claim 3, wherein the pin slides along the cam surface as the second tubular sleeve member rotates between the unlocked position and the locked position. 6. The hand tool of claim 1, wherein the tool head is removably attachable to handle assembly. 7. The hand tool of claim 6, wherein the tool head is one of a spade shovel, a square shovel, a rake, and a broom. 8. The hand tool of claim 1, wherein the first shaft segment and the second shaft segment comprise wood. 9. The hand tool of claim 1, further comprising a cam mechanism comprising a curved slot and a pin, the cam mechanism disposed on the first tubular sleeve member and the second tubular sleeve member. 10. The hand tool of claim 9, wherein the cam mechanism is operable to guide the second tubular sleeve member between the locked position and the unlocked position. 11. A hand tool comprising: a first tubular sleeve member extending from an end of a first shaft segment;the first tubular sleeve member having a socket;a pair of elongated slots formed in the first tubular sleeve member;a locking shaft disposed in the elongated slots;a biasing member biasing said locking shaft;a second tubular sleeve member extending from an end of a second shaft segment, the second tubular sleeve member configured and dimensioned for insertion into the socket of the first tubular sleeve member, said second tubular sleeve member rotatable about a longitudinal axis between a locked position and an unlocked position in the first tubular sleeve member;a locking groove formed in an end of the second tubular sleeve member;wherein said locking shaft automatically engages the locking groove when the second tubular sleeve member is rotated to the locked position;wherein the first shaft segment and the second shaft segment are connected end-to-end by the first and second tubular sleeve members to define a handle assembly; anda tool head connected to the handle assembly. 12. The hand tool of claim 11, further comprising a release mechanism, wherein said release mechanism disengages the locking shaft from the locking groove when activated to allow the second tubular sleeve member to rotate from the locked position to the unlocked position. 13. The hand tool of claim 11, wherein the tool head is removably attachable to the handle assembly. 14. The hand tool of claim 11, wherein the first shaft segment and the second shaft segment are differing lengths. 15. The hand tool of claim 11, wherein the tool head is one of a spade shovel, a square shovel, a rake, and a broom. 16. The hand tool of claim 11, wherein the handle assembly comprises a grip. 17. The hand tool of claim 16, wherein the grip is one of a straight grip and a D grip. 18. The hand tool of claim 11, wherein the first shaft segment and the second shaft segment comprise wood. 19. The hand tool of claim 18, where the first and second tubular sleeve members comprise metal. 20. The hand tool of claim 19, further comprising fasteners for securing the first and second tubular sleeve members to the first and second shaft segments, respectively. 21. The hand tool of claim 11, a cam mechanism operable to guide the second tubular sleeve member between the locked position and the unlocked position. 22. A modular hand tool kit comprising: a plurality of handle ends, each of the handle ends having a grip at a first end and an insertion tip at a second end;a plurality of tool heads comprising a spade shovel, a square shovel, a rake, and a broom, each of the plurality of tool heads comprising an insertion tip;a plurality of shaft segments, each of the plurality of shaft segments having an insertion tip at a first end and an insertion tip at a second end;wherein the plurality of shaft segments comprises a first shaft segment and a second shaft segment, wherein the first shaft segment and the second shaft segment differ in length;a plurality of connector assemblies, each connector assembly comprising: a first tubular sleeve member defining a first socket and a second socket,a cam surface formed in the first tubular sleeve member,a second tubular sleeve member defining a first socket,a pin extending from the second tubular sleeve member,a pair of elongated slots formed in the first tubular sleeve member,a locking shaft disposed in the elongated slots,a biasing member biasing said locking shaft in the elongated slots,a locking groove formed in a tip of the second tubular sleeve member,wherein the first socket of the first tubular sleeve member and the first socket of the second tubular sleeve member are configured and dimensioned to receive an insertion tip of one of the handle ends, tool heads, or shaft segments,wherein the second tubular sleeve member is configured and dimensioned to be removably inserted into the second socket of the first tubular sleeve member,wherein the second tubular sleeve member is rotatably about a longitudinal axis between a locked position and an unlocked position with respect to the first tubular sleeve member,wherein the locking shaft automatically engages the locking groove when the second shaft segment is rotated to the locked position, anda manual release mechanism operable to disengage the locking shaft from the locking groove;wherein the plurality of connector assemblies selectably couple the handle ends, tool heads, and shaft segments in a variety of configurations. 23.
