How would I merge a tool weld script and a weld to back script together?

I was wondering on how you would merge these two scripts together. The weld to back script welds the tool (only a part) onto the back part of the torso on a player while the tool weld script allows parts to be connected together. I've been studying this script for a long period of time but it does not seem to be working. Any help?

Weld to Back:

handle = nil

function onUnequipped()
    if script.Parent.Parent == workspace or script.Parent.Parent.className ~= "Backpack" then
        if handle ~= nil then 
            handle:remove()
        end
        return
    end

    local char = script.Parent.Parent.Parent.Character
    if char ~= nil then
        local torso = char:findFirstChild("Torso")
        local tool = char:findFirstChild(script.Parent.Name)
        if torso ~= nil and tool == nil then
            handle = script.Parent.Handle:clone()
            handle.CanCollide = false
            handle.Name = script.Parent.Name
            handle.Parent = char

            local weld = Instance.new("Weld")
            weld.Name = "BackWeld"
            weld.Part0 = torso
            weld.Part1 = handle
            weld.C0 = CFrame.new(0,0,0.6)
            weld.C0 = weld.C0 * CFrame.fromEulerAnglesXYZ(math.rad(90),math.rad(30),0)
            weld.Parent = handle
        elseif torso ~= nil and tool ~= nil then
            if tool.className == "Part" then
                handle = tool
                tool.Transparency = script.Parent.Handle.Transparency
            end
        end
    end
end

script.Parent.Unequipped:connect(onUnequipped)

function onEquipped()
    if handle ~= nil then 
        handle.Transparency = 1
    end
end

script.Parent.Equipped:connect(onEquipped)

Tool Weld:

local BrickTable = {}

function RecursiveGeneric(Parent, Func, ClassLimit)
 for _, Child in pairs(Parent:GetChildren()) do
  if not ClassLimit or Child:IsA(ClassLimit) then
   Func(Child)
  end
  RecursiveGeneric(Child, Func, ClassLimit)
 end
end

RecursiveGeneric(
 script.Parent,
 function(Brick) table.insert(BrickTable, Brick) end,
 "BasePart"
)

local Base = BrickTable[1]
table.remove(BrickTable, 1)

for _, Part in pairs(BrickTable) do
 local Weld = Instance.new("Weld")
 Weld.Part0 = Base
 Weld.Part1 = Part
 Weld.C1 = Part.CFrame:inverse() * Base.CFrame
 Weld.Parent = Base
 Part.Anchored = false
end

Base.Anchored = false
