"We have plenty of monsters," Finnick says, though he says it without any hint of ill-will in his voice, more a quip than a correction. "We just don't have many halberds."

A halberd may be a versatile weapon, but in some ways, that's exactly its problem in Panem. It's so versatile it would be hard to pass off as anything but a weapon, unlike a spear or a trident which are genuine fishing tools as well as convenient weapons. He'd learned to use a trident fishing with his father, not in a fight. Most importantly, though, they don't provide them in the Games. They don't offer training to use them in the leadup to the Games, and they're rarely in the Cornucopia, so they're not part of the Career training Finnick and the other tributes from District Four went through.

There might be more halberds around if weapons weren't illegal in Panem for anyone but the Peacekeepers, who had guns.

"Finnick Odair," he replies, taking Nida's hand and shaking it. "I choose a trident, when I have the option."
