A katana is a type of one-handed weapon that appears in NetHack. When unidentified, it appears as a samurai sword. Snickersnee is an artifact katana.

Generation

All Samurai start with a +1 katana.[1]

Katanas are very rare - only 4 in 1000 (0.4%)[2] of all randomly spawned weapons will be katanas.

samurai player monsters on the Samurai quest and the Astral Plane have a 50% chance to generate with a katana as their main weapon.[3]

Strategy

The primary differences between a katana and a long sword are the +1 bonus to hit, the katana's d10 damage to small monsters (as opposed to d8 for a long sword), and the inability to convert a katana into Excalibur by dipping. A samurai wielding a katana has a chance of performing a shattering blow, destroying a monster's wielded weapon.

Because a katana is the most damaging non-artifact weapon to use the long sword weapon skill, it is often a desirable off-hand weapon for two-weapon combat.

History

The katana first appears in NetHack 1.3d.

The now-defunct Ninja role started with a katana from NetHack 1.3d to NetHack 2.3e. In NetHack 2.2a and 2.3e, Snickersnee could be created by naming any katana.

Origin

Katana is the name used for a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and a long grip to accommodate two hands. It originated in the late 12th century and was most notably used by feudal samurai, worn with the blade facing upward; the official term for these swords is uchigatana (打刀), with katana often referring to other single-edged swords. Though the quality of steel in Japan was relatively poor at the time, the katana produced were considered better than the mass-produced European broadswords of the same era.

The statline for the katana, including the +1 to-hit bonus, is derived from Dungeons & Dragons.

Variants

dNetHack

In dNetHack, maids have a chance to generate with a katana depending on whether or not the player is a Samurai. dNetHack also introduces Kiku-ichimonji, an artifact katana that replaces Snickersnee (which is changed to a knife) as the Samurai's first sacrifice gift.

SlashTHEM

In SlashTHEM, another artifact katana, Nightingale, is introduced as the first sacrifice gift for the revived Ninja role. Kiku-ichimonji retains its role from dNetHack, while Snickersnee is still present, but is instead obtained through a different method.

Encyclopedia entry

The katana is a long, single-edged samurai sword with a
slightly curved blade. Its long handle is designed to allow
it to be wielded with either one or two hands.
