Why do my weapons break whenever I equip them?

I'm trying to create two weapons, both with a handle on it. So to be clear, I am making a single tool that has two weapons in it. I just cannot get it to work no matter what. I have tried welding the whole thing together and I've also tried to weld just the two weapons by themselves if that makes any sense. All I can say is that I have had no success with making these weapons go by my hands. The only thing that happens is the weapon goes into my right hand and that's it, but I don't want that to happen, i want one weapon in one hand and one weapon in the other hand. Please tell me what I am doing wrong.

If I put this code in a local script in the weapon, the handle goes in my hand... but literally nothing else, not even the other handle. I have named them correctly, handle and handle1.

player = game.Players.LocalPlayer
character = player.Character
LArm=script.Parent.Parent:WaitForChild("Left Arm")
RArm=script.Parent.Parent:WaitForChild("Right Arm")
function KaiWeld()
        local w1 = Instance.new("Weld")
        w1.Parent = script.Parent.Handle
        w1.Part0 = w1.Parent
        w1.Part1 = script.Parent.Handle-------- This is the weapon that goes in the character's Right hand
        w1.C1 = CFrame.fromEulerAnglesXYZ(1, 0, 0) * CFrame.new(RArm.Position.CFrame.new(0,0,0),0,0)

        
        local w2 = Instance.new("Weld")
        w2.Parent = script.Parent.Handle
        w2.Part0 = w2.Parent
        w2.Part1 = script.Parent.Handle1-------- This is the weapon that goes in the Character's Left hand
        w2.C1 = CFrame.fromEulerAnglesXYZ(0, 0, 0) * CFrame.new(LArm.Position.CFrame.new(0,0,0),0,0)
end
script.Parent.Equipped:connect(KaiWeld)
script.Parent.Unequipped:connect(KaiWeld)

I also have this piece of code which basically keeps the weapon together. Without this, the weapon just falls apart and breaks. I don't know why, but this script won't let me choose the position of the handles and I want to be able to choose the position of EACH handle.

function weld()
	local parts,last = {}
	local function scan(parent)
		for _,v in pairs(parent:GetChildren()) do
			if (v:IsA("BasePart")) then
				if (last) then
					local w = Instance.new("Weld")
					w.Name = ("%s_Weld"):format(v.Name)
					w.Part0,w.Part1 = last,v
					w.C0 = last.CFrame:inverse()
					w.C1 = v.CFrame:inverse()
					w.Parent = last
				end
				last = v
				table.insert(parts,v)
			end
			scan(v)
		end
	end
	scan(script.Parent)
	for _,v in pairs(parts) do
		v.Anchored = false
	end
end

weld()
script:Remove()

That should work. Just be sure that the script is in the weapon.

tool = script.Parent
handle = tool:WaitForChild("Handle")
Types = {"Part","WedgePart","TrussPart"}

function Weld(obj)
	local w1 = Instance.new("Weld",handle)
	w1.Part0 = handle
	w1.Part1 = obj
	w1.C0 = handle.CFrame:inverse()
	w1.C1 = obj.CFrame:inverse()
	
	obj.Anchored = false
end

function Confirming()
	for _,part in pairs(tool:GetChildren()) do
		if part.Name ~= "Handle" then
			for _,type in pairs(Types) do
				if part:IsA(type) then
					Weld(part)
				end
			end
		end
	end
	handle.Anchored = false
end
