Just completing my undergraduate, four-year degree in mechanical engineering, I felt it necessary to share that since the first day of classes, I have been using a Graphgear 1000 (0.5mm). This pencil has been through everything (many many bad exams) and has never let me down. The build is sturdy, reliable and comfortable. The appearance is technical and has attracted many compliments (not joking). My handwriting is much better when I write with this pencil. I have a bad habit of chewing on the eraser cap during assignments and exams, yet the cap is un-deformed and perfectly functional.
If you can keep track of a pencil for a long period of time, you can count on this device to last. The price is undoubtedly supported.
Unfortunately, this pencil will not provide answers during exams. Otherwise, it will stick by your side for all of time.
Thank you for reading my ridiculous review of a pencil.
