Self-proclaimed Stationery King Masayuki Takabatake runs B-LABO, a "stationery research site" out of Japan that covers all manner of unusual desktop implements. Take a look at this nutty multifunctional ruler, manufacturer unknown:

Or this ballpoint pen that comes with a mecha action figure:

Or this odd pair of shredder scissors that can apparently be used to destroy both documents and CDs.

In this photo, you can see the little scoring point between the two wheels.

The idea is that you pop a CD onto the nub then rotate it. I'm guessing you can then pop the core out, so no one can load the CD?

From Takabatake's Instagram, this Ninipie highlighter with a little friend:

"Through this site, I would like to spread information to many people so that they can use stationery more enjoyably," Takabatake writes. "I would like to disseminate miscellaneous information based on various interests, focusing on stationery and topics using stationery."

If you're looking for unusual forms, dig through B-LABO or Takabatake's Instagram, you're bound to find something you've never seen before.
