The invention comprises tools for forming beads on one or more filaments using a malleable material for the bead. The tools exert bead-forming forces radially inward toward the filament and axially along the filament toward the center of the bead. The tools comprise pliers with jaws which meet flush with each other over at least a portion of the jaw face. Aligned cavities are formed in each jaw face wherein each cavity's dimension across the jaw face is less than the width of the jaw face. Grooves, aligned generally transverse to the width of the jaw face provide a filament-receiving channel between the cavity and the edge of the jaw face. Malleable material encompassing the filament is aligned between the aligned cavities and the jaws are closed. The radial force of the cavity walls on the malleable material deforms the malleable material radially and the walls of the cavity exert a force axially to form a bead. Tools with cavities having textures embossed, engraved, or otherwise patterned in relief on the cavity walls may be employed to impress a texture or design on a formed bead. Multiple filaments may be crimped together with this invention.
