The greatest tool in the universe is the pen. The greatest sub-specie of the pen is the Rotring Pen - or in smaller words: technical pen.

You would assume a pen without a nib would be rendering suicide, but oh how wrong you would be. They cost a lot. Let's just say it would be cheaper to donate a kidney than invest in one, but 300 bucks does not come without benefits.

(Mrs Bunneh Rotring) ...

Owning one makes you feel like you've been lied to your entire life. I've been short-changed!
This thing is worth the possibility of ink poisoning, and if you get bored you can always stab somebody with it.
Fuck the fine liner. Rotring is to fine liner as bacon is to broccoli - green and only edible after being drowned in tomato sauce.  

It writes on Cromalux Card for christ sake!
Okay.. I can seem I'm losing you.
Just buy the damn pen.
Its Jesus in an inkwell.
