This may be posted somewhere else, but I've looked in three different places and found three different answers.
In the Pathfinder Campaign Setting, the Elven Curve Blade costs 24gp, does 2d6 damage and has a crit multiplier of x3.
In the Pathfinder Reference Document on Paizo's site, it costs 80 gp, does 1d10 damage and crits as 18-20 (x2).
In another SRD I found off the paizo site, it costs 90gp, does 1d10 damage and crits as 18-20 (x2).
So which one is it? :)
