Why does resources.load not work or what am I doing wrong?

I am trying to make a path file that directs the system to my folder with all of my icons in it so i can use them ,but for some reason it is not working. When I start the game the icons just don't show up in the crate or inventory. Am I using it wrong or something? Here is the script that I am using.

 using UnityEngine;
 using System.Collections;
 
 public class ItemGenerator : MonoBehaviour
 {
     //PATH NAME RIGHT HERE
     private const string meleeWeaponPath = "Icons/Weapons/Melee";
 
     void Start()
     {
 
     }
     public static Item CreateItem()
     {
         //DECIDE WHAT TYPE OF ITEM TO MAKE
 
         //CALL THE METHOD TO CREATE THAT BASE ITEM TYPE
         Item item = CreateWeapon ();
             //FILL IN ALL THE VALUES FOR THAT ITEM TYPE
             item.name = "W: " + Random.Range (0, 100);
 
         //RETURN NEW ITEM
         return item;
     }
     private static Weapon CreateWeapon()
     {
         Weapon weapon = CreateMeleeWeapon();
 
         return weapon;
     }
     private static Weapon CreateMeleeWeapon()
     {
         Weapon meleeWeapon = new Weapon (10.0f, 0.0f, 3, false, 0, false);
     //IN THE ARRAY BELOW YOU DEFINE ALL THE NAMES OF THE ITEMS
         string[] weaponNames = new string[3];
         weaponNames[0] = "Machete";
         weaponNames[1] = "Hunting Knife";
         weaponNames[2] = "Handmade Hachet";
 
         meleeWeapon.name = weaponNames[Random.Range(0,weaponNames.Length)];
         meleeWeapon.description = "A fast bladed weapon";
             //I AM TRYING TO USE RESOURCES.LOAD RIGHT HERE
         meleeWeapon.icon = Resources.Load (meleeWeaponPath + meleeWeapon.name) as Texture2D;
         meleeWeapon.rarity = RarityType.Common;
         meleeWeapon.curDurability = 150.0f;
         meleeWeapon.maxDurability = 150.0f;
         meleeWeapon.weightAmount = 1;
 
         return meleeWeapon;
     }
 }
 
 public enum ItemType
 {
     Armor,
     Weapon,
     Consumable,
     Placeable
 }

Please help me!
