Abstract

Abstract Disclosed is a double-purpose hand tool comprising two action members pivotably coupled together by a pivot substantially at their middle portions, the two action members being formed with a pair of shear portions at two corresponding ends thereof and a pair of plier portions at the other two corresponding ends thereof; a biasing means associated with the two action members which can bias the pair of shear portions apart and can bias the pair of plier portions apart; and two grip members, each of them being pivoted about the pivot at one of its ends and formed with a space and an abutment portion therein so that each of the two shear portions can be received in its related space and abut against its related abutment portion to expose the two plier portions, and each of the two plier portions can be received in its related space and abut against its related abutment portion to expose the two shear portions.
