Abstract: Tools for rotating fasteners, methods of utilizing the tools, and methods of manufacturing the tools. The tools include a gripping region, a fastener receptacle, and an interlock structure. The gripping region is configured to be gripped by a user of the tool. The fastener receptacle is shaped to receive the fasteners and includes a fastener-receiving opening on a fastener-facing side of the tool. The fastener-facing side faces in a fastener-facing direction. The fastener-receiving opening is sized to permit the fastener to enter the fastener receptacle from the fastener-facing side of the tool. The interlock structure is configured to interlock with the fastener while the fastener is received within the fastener receptacle. The interlock structure also is configured to prevent motion of the tool away from the fastener in a fastener-opposed direction, which is opposed to the fastener-facing side of the tool, while the interlock region is interlocked with the fastener.

Abstract: Disclosed is a tool, such as pliers, with handle offsets and stop features. In an embodiment, the tool has a minimum of about 0.50 inches of clearance between handles in an area where a user's index finger contacts the handles. This is accomplished by offsetting upper and lower handles of the tool. For example, the lower handle may be offset about 1.10 inches from a pivot point between the handles. Similarly, an end of the upper handle may be offset by about 1.150 inches from the pivot point when jaws of the tool are adjusted to a closed position.
