A wire strainer including: drive means comprising a mounting block with a drum mounted for rotation relative thereto and actuation means connected to the drum for selectively causing the rotary drum to rotate relative to the mounting block, and a line member operatively connected to the drum in a manner whereby rotation of the drum in one direction causes the drum to pull the line member relative to the mounting block, and locking means for selectively locking the drum against rotation in the opposite direction; first gripping means operatively connected to the block of said drive means and adapted to be releasably attached to a wire to be strained; said line member including securing means for releasably securing said line member to a strainer post or similar anchor; wherein said first gripping means includes two opposed jaw members connected to each other for pivoting movement relative to each other between an open position in which a wire to be strained can be placed therebetween and a closed (or gripping) position in which the wire to be strained is gripped between said jaw members, said jaw members being biased to the closed position by spring means, said spring means having two elongate portions with spaced apart free ends connected to said opposed jaw members respectively, said first gripping means further including a release lever extending from one or the other of said jaw members and at least a portion of said release lever extending generally in the direction of the wire being strained whereby a user may grip said release lever and one of said elongate portions in one hand to squeeze said one portion and said release lever together.
