A T8 screwdriver is included, you need to use an electric drill or manual wrench to open it.
We added screw glue during installation, and it may be difficult for you to remove the screws. An effective way is to heat the screws. For example, use a hair dryer to heat the screws, and soak the tail of the handle in boiling water for three minutes. It is best not to soak the whole knife in water, which may cause rust. In short, heating can make the screw glue ineffective.
