hmm, use public functions i suppose and just name the weapon?
Here's an example with an inventory kind of system

Weapon Name 1

function onCreated() {
  Swords = this;
}

public function onEquip() {
  //Do stuff
}

From another NPC

function onEquip() {
  //Some-how find out it's a sword type of weapon you're equipping, generally by reading a string
  Swords.trigger("Equip", "");
  //Or you could do 
  Swords.onEquip();
  //However, if you didn't use that method, you'd use this 
  findWeapon("Weapon Name 1").onEquip(); //Or the trigger etc
}
