Shirogorov Quantum Latest Model to Enter Serial Production

March 24, 2020

Shirogorov continues to chug along, expanding its catalog of serial production models. The latest design to make the transition from the Custom Division is the Quantum, another sizable offering from Russia’s most famous knife shop. According to Shirogorov this iteration of the Quantum has been rigorously tested to function as a large size EDC.

The Quantum has a dramatic, upswept trailing point blade that runs to 3.74 inches – about at parity for most Shirogorov releases. According to Shirogorov representative Tom, the driving concept behind this blade shape was to provide the most cutting horsepower as possible across the entirety of the edge length. The blade steel is M390, the de facto premium powder metallurgy choice that Shirogorov uses on many knives.

In terms of opening method the Quantum is purely a flipper, cruising as usual on Shirogorov’s Multi-Row Bearing System, which incorporates staggered rows of bearings in a radial shape around the pivot. The deep blade grooves on both sides of the blade may look like cutouts and possible secondary opening methods, but in fact they’re part of a different element of design. They run deep down the blade tang to allow for easier access to the pivot area for cleaning without complete disassembly.

A rugged, accommodating handle accompanies the eye-catching blade. It’s a pattern we’ve seen before in many variations: one large finger groove under the flipper tab, and a dip in the spine as it moves towards the base of the blade. The flowing mill lines recall those on the F3 NS and, on the titanium lock bar, provide some additional texturing to help with disengagement. The Quantum weighs 4.76 oz. and comes with a sculpted titanium pocket clip.

The Quantum entered the Custom Division last summer. Even though the large overall size may not make for a traditional EDC, that is the role that Shirogorov intended for on this serialized release. According to Tom, the knife has been rigorously tested by Sergey Shirogorov against the custom and Custom Division iterations to maximize its utility. “Sergey has himself EDC’d all three of them, usually carrying two at the same time and using each a lot. He first made sure that his custom was EDC-friendly, and then that the features he liked best did migrate over first to Custom Division, and then to serial pieces.”
