Bead Crimp Tool - Mirco Crimper. Never fumble closing tiny crimps again! The Mircro Crimper is the right tool for securing Beadalon #1 Crimp Tubes and size #0 Crimp Beads. Use one firm squeeze to crimp with the inner-position grooves, then use the outer-position grooves to round off the crimp. The jaw grooves are comparably smaller to make a dependable closure on smaller crimp findings.
