Mech Blades are special weapons similiar to Switch Axes. They are very strong and useful weapons.
These weapons have the handle and blade setup of a Switch Axe. However, the Blade setup is wider, and they move up and down. There is also several gears on the inside frame that are visible, which are connected to the blades. On the inside, there is a lance like part that can extend and retract as the blades retract and extend respectively. It can morph between Axe mode and Lance mode using this setup.
It also has a shield hanging on it which is used when in Lance mode.
