1. A method of constructing a metal hand tool having a blade piece with a blade piece proximal end and a blade piece distal end; the blade piece distal end comprising a blade and the blade piece proximal end comprising an elongated tang; a contoured handle having a contoured handle proximal end, a contoured handle distal end, and a hollow interior; the contoured handle distal end being curved; the contoured handle comprised of a pair of symmetrical handle half pieces having proximal and distal ends; each handle half piece comprising a proximal end opening and a notched distal end, the method comprising the steps of:
aligning said handle half pieces with each other;
welding said handle half pieces to each other around outer edges of said handle half pieces, leaving open said contoured handle distal end and forming a handle distal end receiver for said elongated tang;
inserting said elongated tang into said hollow interior through said handle distal end receiver;
welding said blade piece to said contoured handle about said curved handle distal end on either side of said blade piece, wherein the weld between said blade piece to said contoured handle comprises a convexly curved welded connection between said elongated tang and a corresponding convexly curved surface of said contoured handle distal end; and
welding an additional metal tang guide piece having a guide piece tang receiver into one of said handle half pieces, said welding the additional metal tang guide piece comprises welding a metal shaft to one of said handle half pieces and welding said additional metal tang guide piece to said metal shaft.
