Melee Attack

I'm trying to make a melee attack so I put rigidbodies(iskinematic) to object and sword. I also added coliders but the problem is sword may touch the collider when the character moves a bit without waiting my hit command. What can i add to my code to wait for the animation to finish? Here is my code:

 using UnityEngine;
 using System.Collections;
 
 public class Health : MonoBehaviour
 {
     public float health;
 
     void Start()
     {
         health = 100;
     }
 
     void Update () 
     {
         if (health < 0)
         {
             Destroy(this.gameObject);
         }
     }
 
     void OnTriggerEnter(Collider other)
     {
         if (other.tag == "Weapon")
         {
             health -= 10;
         }
     }
 
 }
