The Quantum began as a Sergey Shirogorov custom, won Best Tactical Knife at Blade Show Atlanta in 2019, and moved into the Custom Division that year, with a Damasteel Sprint Run named in the same June announcement. The first serial Quantum, the Quantum 3M, went on sale 21 March 2020 in the Three Bears category, on MRBS over hardened steel washers. Where the F95 and Hati carry drop points, the Quantum has an upswept, Persian-style blade with a full flat grind on a handle slimmer than the F95's, with milling patterns designed for the model; all models except the Ursus have a backspacer. Quantum Gen.2 followed on 18 September 2021. The Ursus tier arrived with the Quantum Ursus NL on 9 December 2021, on SRBS, and the base Quantum Ursus with G10 or wood inlays on 6 April 2022; the Quantum Ursus Lefty of 22 July 2023 was the factory's third left-handed model. A 100-piece Quantum Ti BB in blue anodized titanium appeared in 2024. Custom Division Quantums run on SRRBS in runs of 50, including a Bronze CD in Vanadis 10. The line is current.
