A robotic apparatus comprising first, second, and third wheel assemblies, and a clamping mechanism configured to apply a force for urging the second wheel and the third wheel to pivot in opposing directions towards a plane of the first wheel for securing the first wheel, the second wheel, and the third wheel to the pipe, each wheel assembly including an alignment mechanism for adjusting an orientation of the wheels to allow the robotic apparatus to move along a straight path or a helical path on the pipe. A method for navigating an obstacle on a pipe comprising advancing the robotic apparatus along a helical pathway on the pipe to position an open side of the robotic apparatus in longitudinal alignment with the obstacle, and advancing the robotic apparatus along a straight pathway on the pipe such that the obstacle passes unobstructed through the open side of the robotic apparatus.

A folding pocket utility knife includes a front handle, and a rear handle pivotally mounted to the front handle via a pivot. The rear handle contains a cavity configured to contain at least a portion of the front handle within the cavity. A blade holder is mounted inside the front handle for holding a blade, and a bendable blade strap is attached to the blade holder and to the rear handle. The blade strap extends around an outer circumference of the pivot to move the blade holder from a closed position where the front handle is in the cavity and the blade is completely within the front handle, to an open position where the front handle is not in the cavity and the blade extends from a terminal end of the front handle.
