Sunder weapon property

[Mystic Lemur]

Do any weapons have the "Sunder" weapon property, which gives +2 to CMB to Sunder checks using the weapon?

The Sai has the property "+2 bonus on Combat Maneuver Checks to sunder an enemy's weapon." which sounds like the same thing, but it doesn't have the Sunder property. Should the Sai have the Sunder property?

Swordbreaker and flambard are the only sunder weapons I can find.

The Sai doesn't have the Sunder property because it's only good for breaking weapons, not armor, gear, potions, etc. Swordbreaker and Flambard were the only weapons with the property I found as well.
