Weld/Part auto-deleting when used? (SOLVED)

Hello there! I’ve been trying to work on my own weapon system using this tutorial as a guide for the animation portion; How to animate Tool Parts (Guns, Knifes etc.)

Everything is going well, but for some ungodly reason when I equip the tool the welded part or in this case ‘blade’ auto-deletes after use! I have no idea what’s causing this, and to clarify. The only scripts in this baseplate is the local script handling the welding.

For some reason, it doesn’t do this with a normal part? But with the mesh katana I use it does.

Here are some gyazos with the two tools, hope it adds some visual context.

This is the code for the blade

local rs = game:GetService("ReplicatedStorage")
local players = game:GetService("Players").LocalPlayer

wait()

local tool = script.Parent
local blade = tool.Blade
--local sheathe = tool.Sheathe

repeat wait() until players.Character

--//INITIAL WELD\\--

tool.Equipped:Connect(function()
	
	local weld = Instance.new("Weld", blade)
	weld.Name = "WeaponWeld"
	weld.Part0 = blade
	weld.Part1 = players.Character["Torso"]
	weld.C0 = CFrame.new(-1, 1, -1.5)
	weld.C0 = weld.C0 * CFrame.fromEulerAnglesXYZ(math.rad(0),math.rad(-90),0)

end)

tool.Unequipped:Connect(function()
	
	blade.WeaponWeld:Destroy()
	
end)
