Abstract: A method of manufacturing exercise weights from natural stone material that includes steps of cutting a natural stone, assembling a handlebar and a weight plate, and sliding a locking device or a collar onto the handlebar. The natural stone material may include granite, marble, quartzite, rocks, schist, engineered stone quartz, glass, or amalgams of concrete with glass or granite or marble. The handlebar is designed to hold one or more weight plates with a collar locking system.

Abstract: Multi-tool devices and methods of customizing multi-tool devices in a web-based ordering system are provided. One embodiment of a multi-tool device includes a plurality of compartments, wherein each compartment is configured to house one or more attached tools, one or more removable tools, and/or one or more storage ports. Each compartment includes a moveable portion that is configured to be moveable with respect to the other portions. The multi-tool device further includes at least one pin configured to connect the plurality of compartments together. Each of the moveable portions of the compartments is configured to move between a storage position and a deployed position. When the moveable portions are arranged in their respective storage positions, an outer surface of the multi-tool device has a disk shape, an ellipsoid shape, a truncated ellipsoid shape, a spheroid shape, a truncated spheroid shape, a sphere shape, a truncated sphere shape, an ovoid shape, or a truncated ovoid shape.

Abstract: In a method of fully-integrated rapid synthetic material prototyping, a material for prototyping is selected based on pre-existing criteria. A matching composition of elements or compounds of the material is selected using at least one of materials modeling software, estimated best-choice methods, and personal experience. A predetermined amount for each element or compound of the matching composition is determined to form at least one casting, the size of the casting being determined in advance. The predetermined amounts of the matching composition are mixed. The predetermined amounts of the matching composition are melted or processed to form the casting. The casting is manufactured and processed into at least one sample. Final material properties of the at least one sample are measured. The final material properties of the at least one sample are compared to the pre-existing criteria.
