The Shirogorov tools.

Shirogorov screws are slotted and proprietary, the Ursus hex bits aside, and no hardware-store driver fits them cleanly. Force one and it marks the screw. The right tool is a specific driver cut for a specific screw, and the factory and its collaborators have made several: the Custom Division Tool in its numbered editions, the Cyber Tool that became a production driver in its own right, the Sinkevich drivers that ship with the Touch sets and go missing when a set is resold, the SiDiS pens, and the REK bits that take a standard quarter-inch driver.

Kind by kind below: the bit drivers, the adjustable and collaboration drivers, the pens, the bits. Each opens to its editions and its photographs. The registry lists all of them with filters for kind, maker and fit, and a thumbnail where the record has photographs. How to use one without marking a screw is in the Knowledge Graph article linked at the end.
