How to efficiently make a non-tool AND non-hopperbin weapon?

``I've searched the question I've asked, but the answer was pretty much to weld the weapon to the player's right hand and use hopperbins.

** Problems:**

1. I'm trying to make a weapon without using tools, and I feel like I can do it in a much better way.
   1. Should I copy the weapon and place it into the Character, or should I just put the weapon into the Character?
   2. Are there any other methods I should be using in order to have a more efficient script?
   3. Should I be doing anything else differently in order to have a more efficient script?

2. Is there an easier way to weld? (If you have an answer for this, please post.)
	 I use functions to where it just welds it into its original position, but sometimes the function does not do its job.
	
--------------------------------------------------------------------------------------------------------------------

Code errors: The weapon doesn't weld into its original place.

If this helps, I want it to be like the weapons you see in the ROBLOX game, Shard Online.

(I am using r15 in this script, but it would help me if you could tell me how to turn off r15.)

Code Info: This is a LocalScript located in the StarterPack. There are two unions inside of the LocalScript. The two unions are called Blade and Handle.

Code so far:

~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~
local UserInput = game:GetService("UserInputService")
local Player = game:GetService("Players").LocalPlayer

local Character
local RightHand

local Enabled = true
local Equipped = false


--Equip Function--
	local function Equipped(key, GPE)
		if not Enabled then return end
		Enabled = false
		
		if key.KeyCode == Enum.KeyCode.Q and not GPE then
			if not Equipped then
	
				for _,v in pairs(script:GetChildren()) do
					if v.ClassName == "UnionOperation" or v.ClassName == "Part" or v.ClassName == "WedgePart" then
						local new = v:Clone()
						new.Parent = Character
					end
				end
				local Handle = Character:FindFirstChild("Handle")
				local Blade = Character:FindFirstChild("Blade")
								
				local weld = Instance.new("ManualWeld", Handle)
				weld.Part0, weld.Part1 = Handle, RightHand
				weld.C0 = Handle.CFrame:toObjectSpace(RightHand.CFrame)
				
				local weld = Instance.new("ManualWeld", Handle)
				weld.Part0, weld.Part1 = Handle, Blade
				weld.C0 = Handle.CFrame:toObjectSpace(Blade.CFrame)				
				
				Equipped = true		
				
			elseif Equipped then 
				
				for _,v in pairs(Character:GetChildren()) do
					if v.ClassName == "UnionOperation" or v.ClassName == "Part" or v.ClassName == "WedgePart" then
						if v.Name == "Blade" or v.Name == "Handle" then
							v:Destroy()
						end
					end
				end				
				
				Equipped = false
			end
		end
		Enabled = true
	end
------------------

UserInput.InputBegan:connect(Equipped)

--Gets Character--
	local function GetCharacter(char)
		Character = char
		RightHand = Character:WaitForChild("RightHand")
	end
	
	if Player.Character then
		GetCharacter(Player.Character)
	end
	
	Player.CharacterAdded:connect(GetCharacter)

Basically, I want to know the best methods to make an efficient non-tool and non-hopperbin weapon. I also want to know if there is an easier way to weld.
