A baton
A baton, or nightstick, was a hard stick used by police officers and security officers for self-defense.
The security officers on a devastated planet in the Delta Quadrant were armed with batons. (VOY: "Time and Again")
The call sheet listed this weapon as "police baton". Some of them were later sold off on the It's A Wrap! sale and auction on eBay. [1](X) [2](X)
