peculiar odd looking bar

When I got back to my room, I locked the door and sat down on one of the pillows while I still held onto that metal bar.
What is this thing anyway?
I inspected that metal bar for any answers or clues to what it really was, but all that I could find besides it being a short metal bar was that it had a button on the side of it and what looked to be an opening on one end of the bar.
"Why would any man carry around such a peculiar odd looking bar?" I asked a loud with no one in the room to answer me.
Holding what looked to be like open end away from me I pushed the button and a blue blade came shooting out of the end of the bar.

"Well?" First man said
"She is still alive and short while she did have some male company. But she didn't didn't know him!" Second man said

"It was this late morning and like I said before sir. She didn't know him but he did know her. We're holding him as well. Do you want us to get rid of him?" The second man asked.
"No, just leave him in his cell for now! And make sure she doesn't have any more company, male or female! I want her alive, she's our insurance against future Jedi reprisals." The first man stated with a evil grin on his face. "Check and make sure that her door stays locked from now on."
"Yes sir!" The second man quickly stated as his finger flipped a switch.
