Fluidsteel (3.5e Equipment)
From D&D Wiki
The iridescent silvery weapon seems almost to flow as you swing it. Fluidsteel is an alloy of mithral, quicksilver and iron.
Despite the name, fluidsteel is not literally fluid, nor is it technically steel. A finessable weapon made of fluidsteel properly sized for the wielder may be used as though with the Weapon Finesse feat. If the wielder does have the Weapon Finesse feat, he or she gains an additional +1 bonus on attack rolls.
Fluidsteel adds 20,000 gp to the weapon's market price.
Fluidsteel has 9 hit points per inch of thickness and hardness 15.
