A lower cutter 44 has a body portion v46 having a hole
48 therethrough and a plurality of forwardly extending
shearing blades 50, ‘similar to blades 36, spaced laterally
apart. Said handle angular attaching portion 26 is con

thereof by extending into a sleeve holder 52 that is held
to, and over, said body 32, by rivets 54 that extend
