Abstract
The present disclosure describes a handle system for use with finishing tools utilized to finish wallboard joints. A finishing tool may be connected to the handle system and moved relative to a wallboard joint to appropriately apply mastic over the joint. In one embodiment, the handle system includes an elongate handle body having a tear drop cross-sectional shape. The shape enables the handle body to fit ergonomically within a user's hand and improves the user's ability to resist torque tending to cause the handle body to twist and a connected finishing tool to come out of contact with wallboard during use. The handle system further includes a pivoting connector assembly that permits a connected finishing tool to rotate relative to the handle body and that has a unique pivot pin that allows mastic to flow through the handle body, through the pivoting connector assembly, and into the connected finishing tool.
