Would a Cutter brick work?

script.Parent.Touched:connect(function(hit)
        if hit.Planks and hit.Name == "Log" then
            print("lol")
            planks = hit.Planks.Value
        for i = 1, planks do
            print("lol")
            part = Instance.new("Part")
            part.Position = hit.Postion.Vector3.new()
            print("lol")
        end
    end
end)

Im trying to write a script that when a Log touches the brick it cuts up into the amount specified by a intvalue in the Log named planks. Also. I cannot figure out how to make the brickcolor of the new part the same as the log.
