A grinding kit includes a grinding unit having a body defining an inner cavity, the body having a receiving end a depositing end. The grinding unit includes a plurality of grinding surfaces disposed within the inner cavity of the body and a drive shaft coupled to the one or more grinding surfaces. The grinding kit includes a first handle configured to removably couple to the drive shaft and configured to rotate about a first axis of rotation while coupled to the drive shaft to drive movement of the plurality of grinding surfaces. The grinding kit includes a second handle configured to removably couple to the drive shaft and configured to rotate about a second axis of rotation while coupled to the drive shaft to drive movement of the plurality of driving surfaces, the second axis of rotation being different from the first axis of rotation

A smoking accessory assembly facilitates storing and transporting accessories for grinding smoking matter and rolling the smoking matter for smoking. The assembly includes a housing having a plurality of compartments. A grinder has a plurality of grinder teeth and a peripheral wall enclosing the grinder teeth. A plurality of cap teeth is coupled to and extends from a top cap. The grinder is insertable into the top cap for grinding plant matter. A funnel tapers away to a tube section extending from a base of the funnel. Openings extend through the grinder for passing ground plant matter through the funnel and into the tube section. The tube section is open for passing the ground plant matter into a rolling paper wrapped around the tube section.

The invention includes manually operated portable multi-functional herb grinding and vertically dispensing means. The said means is a portable herb grinding device, with storage for raw unused and finished ground dried herbs, that allows grinding and precision vertical dispensing of dried herbs. The said herb grinding device comprising of a manually operated mating grinding rotor and stator, the first of which includes raw material storage and the second part, which removably connects to the said first part, has an integrated storage chamber and precision dispenser. The said first part rotates during the grinding operation and accommodates storage of unused herbs. The said second part is stationary during the grinding operation and accommodates the storage and vertical precision dispensing of the ground product. The dispensing mechanism on the end which can be opened allowing the user to vertically dispense the ground herb in a precise manner or closed for storage or transport.

A container stores, grinds, and measure material. The container includes upper and lower grinding sections that are mated together and rotated to grind the material. A collection section is below the lower grinding section and includes a mesh screen to filter particulate. The mesh screen also functions as a scale to weigh the contents in the collection section. An electronic housing includes a display, microcontroller, one or more buttons, a communications device, and a power supply. Below the electronics housing is a container section retained by a container holder that also includes a scale. The container is enabled to communicate with an external computing device through an application to send and receive data and commands.

An herb cutter having interchangeable grates and matching blades that includes a top chamber for holding herbs before cutting, a bottom chamber for holding herbs after cutting, and a grate positioned between the chambers is disclosed. The grate has multiple slots, each with at least one sharp or serrated edge. A rotatable rod extends across the grate, with a crank and handle connected to it. Multiple blades are attached to the rod, fitting within the slots to cut the herbs when the handle, crank, and rod are rotated. The slots and blades have corresponding lengths. The grate is a circular plate, and each blade is serrated with a central hole fitted about the rod. The cutter also includes spacers separating the blades, a middle shell and a lower funnel retaining the grate, and a lid covering the top chamber. The grate and blades are interchangeable.

A carrier pipe is protected from corrosion by being received inside a casing at a location above ground. The casing, which can be formed from a polymer, defines a gap extending around an exterior surface of the carrier pipe. In one embodiment, the gap is substantially filled with a potting material having a corrosion-resistant property. In another embodiment, a self-contained impressed current cathodic protection system is received in the gap. A pull head is installed on the carrier pipe and/or casing for pulling the pipe assembly, including carrier pipe, casing, and elements received in the gap, into an underground bore as a single unit. In some embodiments multiple pipe assemblies are pulled together into the same bore.
