What kinds of tools did the Ancient Greeks use for gardening? And how do they differ from their modern counterparts?

I'm currently writing a story that explores Ancient Civilizations, such as Ancient Greece and Ancient Egypt. I have a character who originates from the former - a former slave who'd worked in the gardens of their owner - and one major plot point involves her killing her owner with a tool of sorts. I'd love to get on with writing this scene but I can't describe a fight scene without knowing what the weapon looks like and how it'd typically function.
