Abstract
A laminar staple comprising two walls arranged at an angle and two ribs which protrude laterally from the walls; the walls and the ribs form a substantially W-shaped profile which has a cutting edge at one end and a striking edge at the opposite end; the staple is peculiar in that the ribs enclose, by means of their respective walls, an angle whose value decreases from the cutting edge to the striking edge.
