Asterix And The Golden Sickle by Rene Goscinny

When the village druid's treasured sickle is irreparably damaged, two indomitable Gauls set off for the Roman city in search of a master goldsmith to make a new one; their mission turns into a rollicking coast‑to‑city adventure full of pirate skirmishes, run‑ins with Roman troops, comic misunderstandings and displays of strength and cunning as they race to secure the precious tool needed to harvest mistletoe for the village’s secret potion.
