these are the best pliers that i have found for bending small wire or even styrene rod. you wont use these all the time but when you need to make a loop or a 180 turn with wire you will love these. i have another set but these work alot better having the indent on the other arm of the pliers. Highly recommend

This pliers does an excellent job bending coupler trip pins to their proper height for flawless magnetic uncoupling. The tool is basically a hand operated brake press and can be used to spread or close the trip pins distance from the coupler, depending on your placement of the punch and die of the pliers.
