1. A hand tool system comprising: a haft having a haft longitudinal axis;an offset-L component comprising a releasable first attachment means and a releasable second attachment means, the second attachment means oriented at about 90 degrees to the first attachment means; anda digging and cutting head comprising a blade, the blade comprising: a planar central panel in the shape of an obliquely truncated acute isosceles triangle, the base of the isosceles triangle defining a hoe tip;a right panel meeting the central panel at a bend having an angle of about 8 degrees and having a tip edge meeting the hoe tip at an angle of about 135 degrees, the tip edge and the hoe tip together defining a spade tip; anda left panel meeting the central panel at a bend having an angle of about 8 degrees and having a top edge defining a foot cleat; anda mount for releasably attaching the digging and cutting head to the haft or to the offset-L component, and defining a mount longitudinal axis,wherein the mount and blade are affixed one to another such that: the mount longitudinal axis lies within a plane substantially normal to, and substantially bisecting, the central panel isosceles triangle; and the mount longitudinal axis intersects the plane defined by the central panel at an angle of about 15 degrees;wherein, the haft, offset-L component, and digging and cutting head may be selectively releasably assembled: into a spade-like configuration, by attaching the first attachment means to an end of the haft and attaching the mount to the opposite end of the haft, and in which the second attachment means functions as a handle extending substantially perpendicular to the haft longitudinal axis and the haft is angled relative to the spade tip; orinto a hoe-like configuration, by attaching the first attachment means to an end of the haft and attaching the mount to the second attachment means, and in which the hoe tip is substantially normal to a plane containing the haft longitudinal axis and the mount longitudinal axis. 2. The hand tool system of claim 1, wherein: the identical angles of the central panel isosceles triangle are about 80 degrees; anda plane bisecting the 135 degree angle defined by the meeting of the tip edge and the hoe tip, and normal to the plane defined by the central panel, intersects at an angle of about 22.5 degrees, a plane substantially normal to the plane defined by the central panel and containing the mount longitudinal axis. 3. The hand tool system of claim 2, wherein: the left panel is curved and the foot cleat is corrugated. 4. The hand tool system of claim 1, wherein: the mount and the first attachment means each comprises a longitudinally extending chamber having a cross section substantially in the shape of a Reuleaux triangle; andthe two ends of the haft and the second attachment means, each comprise a stub configured for mating engagement with any one of the longitudinally extending chambers. 5. The hand tool system of claim 4, wherein: the mount chamber has a stub receiving opening and a securement opening; andthe second attachment means further comprises a toggle manually rotatable between an insertion position in which the toggle does not impede movement of the stub into the stub receiving opening and an engagement position in which the toggle engages the securement opening so as to impede withdrawal of the stub from the mount chamber. 6. The hand tool system of claim 4, wherein: each stub includes a depressable projecting catch; andeach chamber includes a catch opening configured for receiving the catch when the stub is inserted into the chamber;whereby, when the catch is in the catch opening, the catch impedes withdrawal of the stub from the chamber, and the catch may be manually depressed so as to permit withdrawal of the stub from the chamber. 7. The hand tool system of claim 4, further comprising a rake head comprising two or more hingedly connected tine holders, each tine holder comprising: a tine set comprising a plurality of tines resiliently biased to move to, and remain in, a splayed arrangement; anda longitudinally extending chamber having a cross section substantially in the shape of a Reuleaux triangle configured for mating engagement with one of the stubs;wherein, the haft, offset-L component, and rake head may be selectively releasably assembled with the haft mounted to one of the tine holders and the offset-L component mounted to another of the tine holders, whereby the offset-L component may be manipulated to articulate the hinged connection between the tine holder to fold the rake head when gathering a volume of material in the tines. 8. The hand tool system of claim 7, wherein each tine holder further comprises a tine furler assembly comprising: a track fixed relative to the tine set and substantially aligned with the tines;a car mounted to, and slidable along, the track;a tine bridge spanning the tines of the tine set and having a slot corresponding to each such tine and within which each such tine is interposed, wherein the tine bridge is pivotally attached to a tine in the vicinity of an end of the tine bridge; anda linkage strut attached at one end to the car and attached at the other end to the tine bridge at the end of the tine bridge opposite where the tine bridge is pivotally attached to the tine,wherein the tine set may be brought into a furled arrangement by moving the car towards the tine set so as to bring the tine bridge into an angled orientation relative to the tines. 9. The hand tool system of claim 8, wherein the tine bridge is curved whereby the furled arrangement is a curved furled arrangement. 10. The hand tool system of claim 4, further comprising a claw hammer head comprising: a hammer face;a longitudinally extending chamber having a cross section substantially in the shape of a Reuleaux triangle configured for mating engagement with one of the stubs; anda plank lifting lug. 11. The hand tool system of claim 4, further comprising a snow shovel head comprising: a snow shovel blade; anda plurality of longitudinally extending chambers angled relatively to each other, and each chamber having a cross section substantially in the shape of a Reuleaux triangle configured for mating engagement with one of the stubs;wherein the haft, offset-L component, and snow shovel head may be selectively releasably assembled: into a snow shovel-like configuration, with the haft stub inserted in one of the snow shovel head longitudinally extending chambers; andinto a snow-draw configuration, with the offset-L component stub inserted in one of the snow shovel head longitudinally extending chambers and the haft stub inserted in the offset-L component longitudinally extending chamber. 12. The hand tool system of claim 11, further comprising a second haft wherein the hafts and snow shovel head may be selectively releasably assembled into a double-handled snow shovel-like configuration, with one of the stubs of one of the hafts inserted in one of the snow shovel head longitudinally extending chambers; and one of the stubs of the other of the hafts inserted in another of the snow shovel head longitudinally extending chambers. 13. The hand tool system of claim 4, further comprising a garden fork head comprising: a fork; anda longitudinally extending chamber having a cross section substantially in the shape of a Reuleaux triangle configured for mating engagement with one of the stubs. 14. The hand tool system of claim 1, further comprising additional hafts wherein the hafts have lengths different from each other. 15. The hand tool system of claim 1, further comprising: a second haft wherein the hafts have different lengths; andadditional heads each interchangeable with the digging and cutting head. 16. The hand tool system of claim 15, wherein the additional heads are selected from the group consisting of a rake head; a claw hammer head, a snow shovel head, a garden fork head, and combinations of two or more of the foregoing.
