Use the Kukri's curved core to make Boomerangs! The First Larp safe Boomerangs
Be it making it out of pure foam with a few weights in the tips or using the core of the Kukri which is already curved. (however cost wise and safety for most larps I would imagine pure foam and weighted tips would be the best bet.
No one else does Boomerangs, need some Aussie love!
