Shirogorov Quantum Custom Knife M390 Blade Titanium Handle Exceptional Quality

Shirogorov Quantum Custom Knife M390 Blade Titanium Handle Exceptional Quality

SKU: EA-8549

A masterpiece of knife making from Shirogorov Custom Division


The Quantum is one of the latest and most sought after models from Shirogorov brothers, the prominent Russian company. The Quantum is a large EDC knife with a dramatic sweeping Persian blade, fitted into a masterfully machine titanium handle. The Quantum was designed and tested rigorously by Shirogorov for superior field performance. It's not surprising that the knife was awarded the prestigious title of "Best tactical Folder" at the 2019 Blade Show.


Like other Shirogorov knives, the design language is simple, elegant and eye catching. The titanium handle is exceptionally comfortable in hand thanks to the ergonomic design and fully chamfered edges, M390 steel is the choice for the blade to ensure unparalleled edge retention and durability. The blade features a beautiful upswept edge that flows with the milling lines and curvature of the handle. The vapour finish on the blade is classy and matches up perfectly with the handle finish.


Shiros are best known for their amazing action and the Quantum is no exception. The blade flies out fast and hard due to perfect weight of the detent. The Multi Row Bearing System (MRBS) coupled with precision machining gives you one of the smoothest, glass-like closing actions you'll ever see. This is aided further by the weight of the large blade for a truly remarkable action.
