If "tools" meant some sort of screw driver I'd welcome that. If there are any parts that have to bend to open the case these will break in the long run and are less reliable in my experience (e.g. the phone's back would slide off when pulling it out of the pocket, experienced that with my old BB Q10). Some really small torx screws that can't fall out of their holes even when loose would be optimal. If they also shipped a little screwdriver that fits onto one's key chain I'd be more than happy with that solution.
