Generation
Archeologists have a 1⁄10 of chance of starting the game with a tin opener, while Tourists have a 1⁄25 chance of starting a game with one.[1][2]
Descriptions
Applying or wielding a tin opener before opening a tin to eat will reduce the number of turns required to do so. The exact number of turns required to open a tin with this tool depends on its beatitude: 0-2 turns if the tin opener is cursed, 0 or 1 turns if uncursed, and 0 turns if blessed.[3]
You can only apply a tin opener if you have at least one tin in your inventory - doing so will prompt you to choose which tin you want to open, and you can also wield it before manually opening the tin via e. Wielding a tin opener by applying it will not take up an additional turn if you immediately open a tin when prompted.[4]
Though a tin opener is not a weapon or weapon-tool, a cursed tin opener will weld to the player's hand when wielded.[5]
Strategy
Applying a tin opener to wield it and immediately opening a tin saves a turn compared to wielding the tin opener with w, which may prove important when eating a tin of a monster that cures stoning or in a turn-count speed ascension. Using a blessed tin opener is also the only way to guarantee that a tin is opened immediately, since even a blessed tin may otherwise take 1 turn to open, during which you may be interrupted.
History
The tin opener first appears in Hack 1.0.2 - from this version to NetHack 3.0.0, the item was called a can opener.
From Hack 1.0.2 to NetHack 3.6.1, including some variants based on those versions, applying the tin opener would only display a message instructions to wield it before eating a tin; Tourists with a tin opener in their starting inventory would begin the game wielding it, and should ideally unwield it before attempting melee combat. The ability to apply a tin opener was added in NetHack 3.6.2.
Variants
Some variants based on NetHack 3.4.3 may lack the updated behavior of tin openers from later versions.
UnNetHack
In UnNetHack, the iron golem found in the forest within the Ruins of Moria has a 1⁄2 chance of generating with a tin opener.
Encyclopaedia entry
Less than thirty Cat tribes now survived, roaming the cargo decks on their hind legs in a desperate search for food.
But the food had gone.
The supplies were finished.
Weak and ailing, they prayed at the supply hold's silver mountains: huge towering acres of metal rocks which, in their pagan way, the mutant Cats believed watched over them.
Amid the wailing and the screeching one Cat stood up and held aloft the sacred icon. The icon which had been passed down as holy, and one day would make its use known.
It was a piece of V-shaped metal with a revolving handle on its head.
He took down a silver rock from the silver mountain, while the other Cats cowered and screamed at the blasphemy.
He placed the icon on the rim of the rock, and turned the handle.
And the handle turned.
And the rock opened.
And inside the rock was Alphabetti spaghetti in tomato sauce.
