Burrs are solid copper washers used in lieu of roves in boatbuilding to make a peened rivet joint. Insert the correct gauge copper nail and push a burr over the tip, cut off excess nail and set using the ball side of a ball pein hammer. While peining it is common practice to hold a lump hammer or a similar massive weight against the head of the nail at the rear.
