ABSTRACT:
A cutter for ribbed sheet metal building panels wherein anvil blocks are mounted on the base table adjacent the shear edge of the base table which normally cooperates with the cutting edge of the swinging shear blade. The anvil blocks define sharp cornered oblique cutting edges shaped according to the shape of the ribs of the sheet metal panel; and the anvil blocks have obliquely oriented fore and aft sides to prevent interfering with the ribs when the sheet metal panels are obliquely oriented with respect to the shearing edge of the base table.
