Custom Division Tool

A Shirogorov screw is slotted and proprietary, with one exception: the Q95 Ursus and F95 Ursus take hex bits. No hardware-store driver fits the slotted screws cleanly, which is why the workshop sells drivers at all and why a tool turns up as a line item on secondary-market listings. The factory tools are collected in their own right: the Custom Division Tool has numbered editions, and the drivers that ship with the Sinkevich Touch sets are the part most often missing when a set is resold. This page is the registry, one row per tool, with what it fits, when it was made and where it is listed. Prices are not here; every band and dated figure is in the price record.

The four kinds

The Custom Division Tool is a titanium bit driver, 4.00 in long, with five bits stored in the handle on a magnetic holder and carbon fiber or marbled carbon fiber inlays in the body. It is the driver for Custom Division hardware, and REK does not make bits for that hardware.

The Sinkevich tools fit the collaboration hardware and pivots. Three designs have shipped, each with a Sinkevich Touch set: the Cyber Tool (2021 and 2022), the Ambi-Tool (2023) and the Capsule Tool (2024 and 2025). The Cyber Tool was later sold on its own as the production Cyber Tool, an adjustable-angle driver with 60 and 90 degree positions.
