A HAND TOOL

摘要

The invention provides a frame (12) of a hack-saw (10) and, particularly, the handle formation (14),defines shoulder formations (22) that define a linear edge (24) on opposite sides of the extensionformation (16), the operative external edge (26) of the extension formation (16) extending perpendicularly with respect of the shoulder formations (22). As such, the frame (12) of the hack-saw (10) can be used as a conventional L-square.
