The Top Notch is a one-of-a-kind headwear item, wearable by all classes. It is a painted cardboard box, adorned with several smaller cardboard pieces, capped by a black fedora. When worn by the Demoman, a patch covers the left eye.
The hat adopts the likeness of Markus "Notch" Persson's personal avatar, a drawing of himself in the artistic style of Minecraft, which he was the lead developer on until the game's official release.
- [Undocumented] The Top Notch was added to the game.
- The name and description of this item reference Markus Persson's internet alias "Notch" and game project "Minecraft", respectively.
- The idea for the Top Notch originated when Notch complained on twitter saying nobody believed he was Notch when he was playing Team Fortress. A reply to this tweet suggested Notch should tell Valve to make a special hat for him to prove it.
- Robin Walker joked during the TF2 Mix-Up Match 4 that "Notch doesn't know, but it makes him take 20% more damage" when asked about the reason for giving Notch the hat.
