not necessary to have
Do not waste you money on the pliers, they are not necessary. Channel locks work the best. The metal clamps are fine and easy to use
3/8 hog rings/ pliers
not happy... ends hit when crimped, 2 out of 4 rings. Returned one pair of pliers because rivet was loose. New pair better but still have issue with ends hitting when crimping. Have to adjust rings to have ends bypass for a good crimp.
