At least I think it's a simile. Metaphor maybe. I need a better word than what I've used. My WIP is low fantasy. Although what I've used works, I'd like something that doesn't involve fruit. I've included the paragraph for context and highlighted where I'm not happy. I just can't think of anything else that's about the size of a watermelon that most people would be familiar enough with to visualize it. Certainly not anything that would be time appropriate. I don't think comparing to a microwave or something similar would do the trick in fantasy. - The paladin swung his war-hammer into both hands. It was massive, the handle was as thick as a grown mans forearm but the paladins fingers closed around it entirely. Almost six feet long with the head of the hammer, it was taller than any of them, except Teyous and Peter. The head of the hammer was the size of large watermelon. Made of solid metal the head alone probably weighed close to 100 pounds. The other end had a design that Preston found familiar but couldn't remember why. The paladin moved more quickly than they would have imagined. He wasn't trying to be silent now, crashing through chairs and tables in pursuit of Crowther, who was dancing across the table tops laughing. - Before anyone says it. I'm aware that warhammers were nowhere near this size. It's meant more as a weapon of intimidation than battle.
