Like the full sized Sandmaster, the Micro Sandmaster has an articulated head for access into tight spaces.
This set is based around the beautifully engineered burgundy aluminium handle of the Sorby Modular Micro tool system. The system is one that can be built part by part, starting with just the handle or in the sets, like this one, to which other blades can be added.
