Quote #4
Or give him cartridges of fine zinc teeth,
Sharp with the sharpness of grief and death. (7-8)
The rhyme on "teeth" and "death" emphasizes the fact that bullets are made for killing, for inflicting death. The cartridge is imagined as a face or mouth with sharp teeth, and it kind of seems like a carnivorous monster, just like the bayonet-blade of the first stanza.
