The system further includes a handle configured for gripping, and a shaft coupled to and extending between the handle and the second face of the base, having a shaft diameter, and extending outward from the base in a direction perpendicular to a plane defined by the second face. The base diameter is at least twice as large as the shaft diameter such that pressure applied to the second face of the base by a foot causes the handle to raise from a ground surface, and the base, handle, and shaft together function as a cane. ## Claims ### Claim 1 A system for reducing the likelihood of falls, the system comprising: a base having a polyhedron shape with: a first face configured to rest on a flat surface, a second face spaced apart from and parallel to the first face, and having a base diameter, at least three sides extending between the first face and the second face, a plurality of metal sheets each coupled to one of the at least three sides, a top metal sheet coupled to the second face, and a raised sheath extending from the second face in a direction away from the first face and having a cylindrical shape; a handle configured for gripping; and a shaft coupled to and extending between the handle and the second face of the base, having a shaft diameter, and extending outward from the base in a direction perpendicular to a plane defined by the second face, wherein: the base diameter is at least twice as large as the shaft diameter such that pressure applied to the second face of the base by a foot causes the handle to raise from a ground surface, and the base, handle, and shaft together function as a cane. ### Claim 2 (depends on 1) The system of claim 1, wherein the polyhedron is a prism. ### Claim 3 (depends on 1) The system of claim 1, wherein the first face and the second face both have a hexagonal shape, and the polyhedron includes six sides extending from the first face to the second face. ### Claim 4 (depends on 3) The system of claim 3, wherein the base includes a plastic body and a bottom defining or coupled to the first face and formed using a sticky material that has a greater coefficient of friction than the top metal sheet. ### Claim 5 (depends on 1) The system of claim 1, further comprising a metallic feature coupled to the handle to facilitate retrieval of the cane using a magnetic retriever. ### Claim 6 (depends on 5) The system of claim 5, further comprising a magnetic retriever having: a retriever handle for gripping the magnetic retriever; a magnet; and a telescoping arm extending between and coupled to the retriever handle and the magnet, and configured to extend to increase a distance between the retriever handle and the magnet and to collapse to reduce the distance between the retriever handle and the magnet. ### Claim 7 (depends on 6) The system of claim 6, wherein the magnetic retriever further includes a connector configured to removably attach the magnetic retriever to a remote object. ### Claim 8 (depends on 5) The system of claim 5, further comprising a magnetic retriever having: a retriever base with a retractable reel coupled thereto; a magnet; and a flexible line extending between and coupled to the retractable reel and the magnet, and configured to be pulled from the retractable reel to extend the flexible line from the retriever base and to be retracted back onto the retractable reel to wind the flexible line around the retractable reel. ### Claim 9 (depends on 8) The system of claim 8, wherein the magnetic retriever further includes a connector configured to removably attach the magnetic retriever to a target object. ### Claim 10 (depends on 8) The system of claim 8, wherein the magnet is configured to be magnetically coupled to each of the metallic feature, the plurality of metal sheets, the top metal sheet, and another metallic feature coupled to another object. ### Claim 11 (depends on 1) The system of claim 1, wherein each of the at least three sides is coupled to one of the plurality of metal sheets. ### Claim 12 (depends on 1) The system of claim 1, further comprising: at least one of a device metallic feature or a device magnet coupled to the walking device; and a magnetic retriever having a retriever connector configured to be coupled to an article of clothing, and having at least one of a retriever metallic feature or a retriever magnet configured for attraction to the at least one of the device metallic feature or a device magnet, such that the article of clothing with the at least one of the retriever metallic feature or the retriever magnet may be used to retrieve the walking device. ### Claim 13 (depends on 1) The system of claim 1, further comprising a magnetic retriever usable to retrieve the walking device via magnetic attraction with metal of the walking device, the magnetic retriever including a clip configured to removably attach the magnetic retriever to a remote object. ### Claim 14 (depends on 1) The system of claim 1, wherein the plurality of metal sheets and the top metal sheet each function as a metallic feature to facilitate retrieval of the cane using a magnetic retriever.
