The outer peripheral surface having the curvature includes a length in the direction of the central axis. A ratio of the length of the outer peripheral surface having the curvature to the length of the tool bit is between about 0.2:1 and about 0.7:1.

A spigot stop removal bit device facilitates removal of a buried spigot stop without having to dig. The device includes a first bit and a second bit each having a respective first end configured for coupling to a driving tool to be selectively rotated by the driving tool. A second end of the first bit is flat. A second end of the second bit is sharpened wherein the second end of the second bit is configured for engaging and cutting into the plug wherein the plug is structurally compromised to facilitate removal of remnants of the plug from the hydrant pipe. Respective lengths of the first bit and the second bit are extended such that the second end of each is configured for engaging a plug positioned in a hydrant pipe.

Fasteners, drivers, and fastener systems constructed wherein example fasteners have driver engageable surfaces on or within a shank tip of the fastener. Example embodiments are included where at least one of the installation and removal surfaces are configured to define a segment of a spiral. Some example embodiments are also included where the installation and removal drive surfaces intersect an enlarged core diameter in an inner transitional surface that extends between the installation and removal surfaces of adjacent wings. Embodiments include fasteners with installation and removal drive surfaces on or within a shank tip of fasteners.

A belt buckle adapted for securing a plurality of tools. The multi-purpose belt buckle system includes a first component for screwing a screw and a second component for holding the first component. The first component is T-shaped and includes various types of screwdriver heads. The second component further includes a slot for holding the first component, at least one open wrench and least one means for connecting a strap/lace.
