The samurai's sword does higher damage than most other melee weapons, however, it lacks the special effects of Jingwei's shocksword or the Shishkebab. On the other hand, it has a higher critical damage than most bladed melee weapons, and has a relatively low AP cost compared to similar weapons, allowing for more attacks in V.A.T.S. The samurai sword is the oldest weapon in the game, originally being wielded by Toshiro Kago, a Japanese samurai.
The samurai's sword can successfully strike about 833 times from full condition before breaking.
Chinese officer's sword
Vampire's Edge - The weakest of the Chinese officer's sword variants, Vampire's Edge weighs only one pound, and is the only variant to use the regular sword's skin.
Jingwei's shocksword - An electrified version of the Chinese officer's sword, the shocksword is much stronger and deals electrical damage over time.
Clover's Cleaver - A Chinese officer's sword that was cut from the base game. It was intended to be used by Clover and was to be the Evil follower unique weapon, much like Fawkes' super sledge and Butch's Toothpick were for the other Karma levels.
Katana - A variant of the samurai's sword that deals much less critical damage, but knocks foes down with critical hits.
The samurai's sword can be found in the waste disposal area of Zeta, accessible through the maintenance level (which can be entered only during the quest "Among the Stars"). It is at the outer southwest area in a closet full of medical supplies (see waste disposal article for a map (B) with the location marked). The sword should be acquired while Toshiro Kago still resides in the engineering core, for after his disappearance it will be gone from the shelves. It can, however, be found later, before the Lone Wanderer enters the Bridge: by simply killing Toshiro and looting his body. No one on the bridge will become hostile.
Has platform::PC When trying to exit the waste disposal area, the teleportation matrix might not work. PC users can fix it by selecting the teleporter in console and use the command "activate". [已核实]
Has platform::PC The sword might not appear if Toshiro Kago has been killed before entering the waste disposal area. [已核实]
Has platform::Xbox 360 The sword may not appear even if Kago is not dead. [已核实]
Has platform::Xbox 360 When decorating your Megaton house, the sword's image will not appear while idle. However, if you look directly at it and get close enough to pick it up, then the option to pick it up will appear - picking it up will place it in your inventory like normal even though you can't see it.

Has platform::Xbox 360 It is possible to acquire two swords. First, get the one in the waste disposal. When you return to the engineering core, drop it right in front of Toshiro. Talk to him and tell him you found his sword and he'll miraculously acquire one. Kill him and it will be on his body (just don't lose/forget the one you dropped). [已核实]
Fixed as of the most recent patch.
Has platform::Xbox 360 It is possible to equip Toshiro with his sword and still retain a copy. Reverse pickpocket the sword onto him, allow him to equip it, and pickpocket it back. [已核实]
