Different script for each item?

I have all of these items that I am defining and I wonder if I should have a seperate script for each item because what happens is you find the item on the ground and then you press e on it to pick it up and then when you press E it adds the item to your inventory. Should I put all of the items in one script or make a seperate script for each item? Here's how it looks right now using the same script for each item: using UnityEngine; using System.Collections;

 public class AllItems : MonoBehaviour
 {
     private const string meleeWeaponPath = "Icons/Weapons/Melee";
 
     public static Weapon AllWeapons()
     {
         //MELEE WEAPONS
         Weapon machete = new Weapon (12.5f, 0.0f, 4, false, 0, false);
             machete.name = "Machete";
             machete.description = "A fast bladed weapon";
             machete.icon =  Resources.Load (meleeWeaponPath + machete.name) as Texture2D;;
             machete.rarity = RarityType.Common;
             machete.curDurability = 150.0f;
             machete.maxDurability = 150.0f;
             machete.weightAmount = 1;
 
         Weapon shovel = new Weapon (20.0f, 0.0f, 2, false, 0, false);
             shovel.name = "Shovel";
             shovel.description = "A blunt tool for shoveling the earth.";
             shovel.icon =  Resources.Load (meleeWeaponPath + shovel.name) as Texture2D;;
             shovel.rarity = RarityType.Common;
             shovel.curDurability = 150.0f;
             shovel.maxDurability = 150.0f;
             shovel.weightAmount = 1;
 
         Weapon woodAxe = new Weapon (25.0f, 0.0f, 1, false, 0, false);
             shovel.name = "Wood Axe";
             shovel.description = "A sharp tool for chopping down trees.";
             shovel.icon =  Resources.Load (meleeWeaponPath + woodAxe.name) as Texture2D;;
             shovel.rarity = RarityType.Uncommon;
             shovel.curDurability = 200.0f;
             shovel.maxDurability = 200.0f;
             shovel.weightAmount = 1;
         
         
         //    BASIC RANGED/Rough Craft
 
 
 
 
 
         //GUNS
 
 
 
 
 
         //LASER WEAPONS
 
 
 
 
 
         return null;
     }
     public static Consumable AllConsumables()
     {
         //FOOD
 
 
 
         //LIQUID
 
 
 
 
         //MEDICINE OR HEALTH RELATED
 
 
 
 
 
         return null;
     }
     public static Armor AllArmor()
     {
         //BASIC AND MODERN
 
 
 
 
         //ROUGH CRAFT
 
 
 
 
         //POWER OR ADVANCED
 
 
 
 
 
         return null;
     }
     public static Placeable AllPlaceables()
     {
         //BUILDINGS
 
 
 
 
         //STATIONS
 
 
 
 
         return null;
     }
         public enum ItemType
         {
             Armor,
             Weapon,
             Consumable,
             Placeable
         }
 }
