Grab one of the metal straps in a pair of vise grips, twist the vise grips in a rolling motion down the seam it should peel back with little force. Do the same on the second strap. Grab the edge of the square with the vise grips and peel the top off. And there you go open clean no sharp edge or ripped sheet metal to cut your self on.
