What's the most radical weapon?

And emphasis on RADICAL, I have a jokey NPC that is just a super cool skater dude bro and such a radical dude needs a radical weapon.........the party may drag him into a fight and I don't know what weapon he'd have. For context he's an arakokra merchant / performer named Tony. Tony the Hawk... I thought it was funny ok?

Anyway, what's the most radical weapon for this most radical dude?
