Invisibility Question

[sdt]

According to the spell Invisibility I can destroy items without ending the spell. What if I try to Sunder something someone is holding (like a weapon); will that end the Invisibility?

Good rule of thumb I use,
If you have to roll and attack, invisibility goes down.

Sunder is an attack action.

Don't remember about Striking an Object though...
