Carya laciniosa Carya laciniosa Carya laciniosa, the shellbark hickory, in the Juglandaceae or walnut family is also called shagbark hickory, bigleaf shagbark hickory, kingnut, big, bottom, thick, or western shellbark, attesting to some of its characteristics. It is a slow-growing, long-lived tree, hard to transplant because of its long taproot, and subject to insect damage. The nuts, largest of all hickory nuts, are sweet and edible. Wildlife and people harvest most of them; those remaining produce seedling trees readily. The wood is hard, heavy, strong, and very flexible, making it a favored wood for tool handles.

Torque multiplier Torque multiplier A torque multiplier is a tool used to provide a mechanical advantage in applying torque to turn bolts, nuts or other items designed to be actuated by application of torque, such as the actuation of valves, particularly where there are relatively high torque requirements. Torque multipliers are often used instead of extended handles, often called "cheater bars". Extended handles use leverage instead of gear reduction to achieve torque. This torque is transmitted through the driving tool and could become dangerous in the case of a sudden catastrophic failure of the drive tool with the extended handle attached. Torque
