Pens as Weapons.

[Orange Lightning]

Heh, those chopsticks look like pens also. Wouldn't that be interestingly utilizable if done well?

I'm also wondering if that TP shank used only one roll.

Sure. They could work. You could use them to hit soft targets really quickly, and at a range. They could be a little grippier, but they would mostly be fine.
But you would never have them! xD They would never be in your pocket or in your shirt. If they were in your backpack, you should really grab something better than chopsticks if you have the time to rummage your bag for a weapon.
For me at the time though, it wasn't too bad an idea. I have chopsticks on me every day anyway.
.....There's this scene in Kiss of the Dragon where Jet Li stabs a guy in the throat with 2 wooden chopsticks. That may have been the inspiration.

Couldn't find it though. Here's a clip from some Steven Seagal movie.
