CFrame offset not working

#1

I’m making a lightsaber fighting game, and I’m trying to offset the blade from the handle after welding them together.
For some reason, the offset code I have (line 11) doesn’t do anything.
Any help is greatly appreciated.

This is my code:

wait()

local lightsaberBlade = workspace["Lightsaber Blade"]:Clone()
lightsaberBlade.Name = game.Players.LocalPlayer.Name.."'s Lightsaber Blade"
lightsaberBlade.Parent = workspace

local lightsaberWeld = Instance.new("Weld")
lightsaberWeld.Parent = workspace
lightsaberWeld.Part0 = lightsaberBlade
lightsaberWeld.Part1 = game.Players.LocalPlayer.Backpack.Lightsaber.Handle
lightsaberBlade.CFrame = CFrame.new(lightsaberBlade.Position) + Vector3.new(0, 10, 0)
#2

I’m pretty sure you can do this by changing the weld’s C0 and C1
If you don’t know, C0 is Part0’s offset and C1 is Part1’s offset, changing C0 moves Part0 and changing C1 moves Part1
