ABSTRACT:
A shear for cutting sheet material which functions by pivoting a specially constructed pointed blade about an axis by means of an arm so that the blade pierces into and then cuts the sheet is described as well as the method for its use. The blade is constructed such that it has double cutting edges forming a point wherein the cutting edge towards the pivot axis for the arm is concave and forms the point with the other cutting edge in a shape which approximates a shark's tooth. The blade pierces the sheet when the arm is pivoted towards the sheet and then cuts outward along a square edged surface on a frame supporting the arm away from the place where the sheet was pierced by the point. The shear is particularly adapted for the hand cutting of U shaped building channel to a predetermined length.
