Ezurian Saber (3.5e Equipment)
From D&D Wiki
The weapon look like a cross between a katana and a saber. Slightly more curved than the regular katana. Unklike a katana, the hilt has a guard, giving the blade parry abilities. The blade form make it more potent at slashing and hacking, unlike a katana or other eastern weapon.
Ezurian sabers are too large to use with one hand without special training, thus is exotic. A character can use a Ezurian Saber with two hand without special training, thus is considered a martial weapon.
