Yes, Catwoman may be in the pic here, but, Batman has used his fair share of Bolas in the day. In fact, it's part of the Utility Belt's Wikipedia page!
Batman uses his bolas to trip and often restrian fleeing suspects. No one escapes the Batman after all. Not only that though, his have the ability to release electric shocks to those that are bound by them, ensuring they don't have the strength to untie themselves.
