Learning to equip weapons etc to character but its not working!

I bet you've seen it all before a million times. But I have scrolled through countless examples and tried with no change. I am currently beginner at both C# and unity.

I am trying to get my model to equip/hold a weapon when i start the game. I have created a child to the hand and turned off mesh and box collider.

I have then created the following C# script;

 public GameObject HookRightHand;

 void start(){
     GameObject sword = GameObject.Find ("sword-1");
     EquipMainHandWith (sword);
 }

 public void EquipMainHandWith(GameObject weapon){
     weapon.transform.parent = HookRightHand.transform;
     weapon.transform.localPosition = Vector3.zero;
 }

}

I have then attached the child to the script which is name HookRightHand.

The weapon prefab is named sword-1, the model used is named sword_wooden. I have tried using both names with no luck.

Everytime i run the game the sword just sits in the air and doesn't follow as intended. What am i doing wrong? or what am i missing?
