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()
