    摘要: A hacksaw frame particularly designed to permit a full stroke of the blade in cutting off so-called ''''drift bolts'''' in a narrow space between wide parallel timbers without injury to the hand of the operator, a frame in which positioning of the blade is such as to both expedite the cut and reduce to a minimum possibility of the blade being broken, and a removable attachment to the frame whereby a pruning blade may be substituted for the customary blade with the saw thus becoming adaptable as a pruning instrument.
