The Top Notch is a one-of-a-kind cosmetic item for 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 avatar, a drawing of himself in the artistic style of Minecraft, which he created and was the lead developer on until the game's official release. Valve silently released this hat in 2011, adding it to Notch's backpack.
- [Undocumented] The Top Notch was added to the game.
- 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% extra damage" when asked about the reason for giving Notch the hat.
- Top Notch is also an adjective which means "first rate" or "excellent".
