No-dachi or O-dachi, the difference being length of handle and the length of blade. but there is also the original name and version of the katana, called the tachi that was very long and was used much like the katana.
It is their traditional weapon.

The specifications of a cold steel Katana have varied over time. The standard modern Katana is 23 1/2 inches long and every one of them has a curved blade.
Katana was the name for the sword.
katana, defiantly katana and it is sharper
its a samurai-type katana, so its about six feet
well, for combat, a shorter katana allows for greater mobility. the only reason it'd be long is for the reach or extra weight, but if you want those just get a Naginata(i personally like these). but as for design, i think it'd have a nice look to it, though make sure to get a full tang katana no matter what as for decorative katana's i found this interesting also, though i think it's just the blade, if i could i would get a diff. sheath, and hand guard
The cursed sword is called Chokuto Reiki
Perhaps you are thinking of the straight shorter blade that ninjas used against the samurai katana? That is the ninjaken, or ninja sword, obviously a technical term in japenese :P. The ninja would have the same length sheaths as the traditional katana, that way with the shorter blade they could draw it fractionally faster, and thusly surprise and kill the unsuspecting samurai.
