How do i check and unequip a tool in a local script?

so this is inside a button that clears your inventory.

script.Parent.Visible = false
local p = game.Players.LocalPlayer
local items = p.Backpack:FindFirstChildOfClass("Tool")
local activated = false

script.Parent.MouseButton1Click:connect(function()
	local tool = game.Players.LocalPlayer.Backpack:GetChildren()

	script.Parent.Parent.Popcatsword.Visible = true
	script.Parent.Parent.TextButton.Visible = true
	script.Parent.Parent.shrek.Visible = true
	script.Parent.Parent.bow.Visible = true 
	for i, child in ipairs(tool) do
		child:Activate()
		child:Deactivate()
		child:Destroy()
	end
	script.Parent.Visible = false
end)

I was a little confused by your post title, but if you're looking for a button that clears your inventory then this would do it:

script.Parent.MouseButton1Click:connect(function()
    for _, tool in ipairs(game.Players.LocalPlayer.Backpack) do
        if Tool:IsA("Tool") then
            Tool:Destroy()
        end
    end
end)

You can add any of the visibility settings you had as needed.

I'm not entirely sure what you were trying to accomplish with activating and deactivating the tool. If that was your intent, let me know and I can try to help.
