The Astrum is a 100 mm flipper designed by Sergey Shirogorov. It began as a Sprint Run stamped 2023, then a First Production on 2024-07-27 and the serial model on 2024-11-30, first shown at the Arsenal show, with a Custom Division line in the same year; the Astrum is the first of the workshop's own models in MagnaCut, after the 2023 Molten Overkill collaboration. The serial knife keeps the First Production's dimensions and weight but changes the blade steel. The liner apron carries fine jimping on its inner face for the thumb, the pattern at the rear of the gray titanium handle is slightly radial rather than parallel as on the First Production, the titanium clip and backspacer match the handle color, the backspacer is suspended along its whole length, and the pivot uses the CPS anti-rotation system. The First Production run was 100 pieces. Custom Division runs followed: 50 pieces in MagnaCut on a card dated 2025-08-19, and 100 pieces with a DamaX blade, Stardust CarboTi scales, a DamaX backspacer and the PLDS pivot system on a card dated 2026-04-21. A Sinkevich Touch edition of 50 was sold at CCKS Fall 2024 with the Capsule Tool. BladeZilla, a YouTube channel, named the Astrum its 2024 Knife of the Year.
