Curved blade

Attack Type: Slash
Fast for: Rogues, Paladins, Rangers	Viable for: Artificers
Uniques: Blade of Sethic, Eagle Talon, Flamberge, the flame sword

Pros: Decent mix of damage, parry and lightness
Cons: Somewhat uncommon, a bit lower on damage scale.
High End Choices: The katana has pretty nice parry, and the orcish sabre does reasonable damage, but neither are exceptional. Eagle Talon from the eagle clan is possibly the best curved blade in game. Or the Flamberge, if you can get it for your skill. See its page for more info. Blade of Sethic possibly good because 2handed, but can't say. See its page.
Two Weapon Choices: Orcish Sabre has been often used, assassins blade and hasashiyyini blade from hasashiyyini both give bonuses to two weapon, the sharpened keen steel scimitars from shieldhand dual decently and give +20 riposte.

Suggested Skill Progression:

0-20 Snickersnee from orc minions.
20-30 Hooked sword from packrat guards in star caverns
30-50 Long Katana from underground forest.
50-100 Katana from Zhammar.
60-100 Orcish Sabre from Dalair or Drakhiya.
0-100 Flamberge, the flame sword sets itself to your ability; it will go down in difficulty if someone of higher skill has wielded it before you, but only if you have the strength to wield it. A workaround if you are too weak is to try having someone with high strength but very low curved blade skill wield it.
