Ever take time to read the City Code for Bend? It's definitely interesting. Like Chapter 5, Offenses, section 5.070:

Possession of a Throwing Star.

(1) Definition: "Throwing Star" means any instrument, without handles, consisting of a metal plate having three or more radiation points with one or more sharp edges, and designed in the shape of a polygon, trefoil, cross, star, diamond, or other geometric shape for use as a weapon for throwing.

(2) A person commits the offense of possession of a throwing star if the person knowingly manufactures, causes to be manufactured, brings into the city, keeps for sale, offers for sale, exposes for sale, gives, lends or possesses a throwing star as defined in section l herein.

(3) Possession of a throwing star is a Class A misdemeanor.

[Section 5.070 added by Ord. NS-l398, passed 6-20-84]

I am simultaneously greatly amused and a bit puzzled by this one. Did we have an epidemic of ninja gangs in Bend in the early 80s to cause such a specific ordinance to get on the books? So far my digging around hasn't revealed any history behind it.

But what's more puzzling is why there's only the restriction on throwing stars. Why not nunchucks? Or swords?
