Trident

As part 5 of my personal project here's the trident, literally "three teeth", or some variation of that, it's been a surprisingly versatile tool in history, serving as a harpoon in fishing, a farming tool to remove leaves and finally as a weapon of war. The harpoon version was the only one had barbed tines to firmly secure fish, which is the exact opposite of what you'd want in a military weapon, hence why this trident might look different than what you might think of when I say "trident".
