Forum:Powertool+ Cursed Armaments Wtf??

what happends if your opponent has monsters and you have Powertool Dragon equiped with Cursed Armaments??Then if powertool would be destroyed you can tribute Cursed Armaments instead, and if it is sent to the graveyard you can equip it to and opponent's monster.So Powertool can't be destroyed.Is it right?, so what do you think?
