The present invention involves a hand-held cutter device that is adapted to be held by a human hand, over a human finger, or between the human fingers. The cutter device includes a generally cylindrical inner sleeve slideably engaged with a generally cylindrical outer sleeve, where each sleeve includes an open end and a closed end. The inner sleeve has an extended position and a retracted position. A blade for cutting various materials is attached to the closed of the inner sleeve. A biasing element is confined between the sleeves and urges the inner sleeve into the retracted position. The closed end of the outer sleeve may include a plurality of flat guide surfaces, at least one straight guide groove, and or at least one guide rib. At least two of the plurality of flat guide surfaces may intersect at about a 90 degree angle and the at least one straight guide groove may be located within any of the plurality of flat guide surfaces.

Having thus described the preferred and exemplary embodiments, the invention is now claimed to be: 1. A cutter device capable of cutting while in sliding contact with one of a variety of sheet materials to be cut, the cutter device comprising: a) an outer sleeve, the outer sleeve having a closed end and an open end; b) an inner sleeve slideably engaged within the outer sleeve, the inner sleeve having a first position and a second position with respect to the outer sleeve; c) a biasing element for biasing the inner sleeve in the second position, wherein the biasing element is disposed between the inner sleeve and the outer sleeve; and d) a blade having a sharp cutting edge extending non-parallel to a longitudinal axis of the cutter device and adapted to slideably engage and cut the sheet material, the blade being attached to the first end of the inner sleeve, wherein the blade extends beyond the outer sleeve when the inner sleeve is in the first position and wherein the blade retracts within the outer sleeve when the inner sleeve is in the second position; and e) a plurality of guide surfaces disposed on an exterior surface of the closed end of the outer sleeve and being angled inward and toward a tip of the closed end, at least one of the guide surfaces angled with respect to the longitudinal axis, wherein two or more guide surfaces are flat and intersect to form a plurality of guide edges initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve. 2. The cutter device of claim 1, wherein the outer sleeve further includes a retaining rib aperture extending radially through the outer sleeve and the inner sleeve further includes a retaining rib projecting radially outward from the inner sleeve, the retaining rib engaging the retaining rib aperture of the outer sleeve. 3. The cutter device of claim 1, wherein the outer sleeve further includes a button aperture extending radially through the outer sleeve and wherein the inner sleeve further includes a button, the button being urged radially outward from the inner sleeve, the button engaging the button aperture of the outer sleeve when the inner sleeve is in the first position for holding the inner sleeve in the first position. 4. The cutter device of claim 1, wherein the closed end of the outer sleeve further includes a guide groove initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve. 5. The cutter device of claim 1, wherein at least one of the guide surfaces further includes an outward projecting guide rib initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve. 6. The cutter device of claim 4, wherein the guide groove is radially aligned with the longitudinal cutting edge of the blade. 7. The cutter device of claim 1, wherein at least one of the guide edges is rounded. 8. A finger-held cutter device capable of cutting while in sliding contact with one of a variety of sheet materials to be cut and capable of being guided in relation to a cutting support surface, the cutter device comprising: a) an outer sleeve, the outer sleeve having a closed end and an open end; b) an inner sleeve slideably engaged within the outer sleeve, the inner sleeve having a first position and a second position with respect to the outer sleeve, the inner sleeve including an open end adapted to receive and slide over a human finger for supporting the cutter device thereon; c) a biasing element for biasing the inner sleeve in the second position, the biasing element being disposed between the inner sleeve and the outer sleeve; d) a blade having a sharp cutting edge extending non-parallel to a longitudinal axis of the cutter device and adapted to slideably engage and cut the sheet material, the blade being attached to the first end of the inner sleeve, wherein the blade extends beyond the closed end of the outer sleeve when the inner sleeve is in the first position and wherein the blade retracts within the outer sleeve when the inner sleeve is in the second position; and e) a plurality of guide surfaces disposed on an exterior surface of the closed end of the outer sleeve and being angled inward and toward a tip of the closed end, at least one of the guide surfaces being angled with respect to the longitudinal axis, wherein two or more guide surfaces are flat and intersect to form a plurality of guide edges initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve. 9. The cutter device of claim 8, wherein at least one of the guide surfaces includes at least one guide groove initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve. 10. The cutter device of claim 8, wherein at least one of the guide surfaces includes an outward projecting guide rib initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve. 11. The cutter device of claim 8, wherein at least one of the guide surfaces includes a first guide groove and a second guide groove, each of the first and second guide grooves initiating near the tip of the closed end of the outer sleeve and extending outward and rearward toward the open end of the outer sleeve, the first guide groove being laterally spaced apart from the second guide groove. 12. The cutter device of claim 8, wherein at least one of the guide edges is rounded.
