    a slitting blade provided with an exposed sharpened cutting edge, said slitting blade being mounted by said body section with its sharpened cutting edge facing rearwardly toward the closed rear end of said slot and extending into said slot from the inner side of said main body section toward the inner side of said arm section to end at a blade tip located in said slot between the front end of said device and the rear end of said slot;

    the inner side of said body section having first and second portions, the first portion extending at an incline from the front end of said device toward the inner side of said arm section, the second portion extending from the first portion to the rear end of said slot parallel to the inner side of said arm section;
