ExtremaRatio - BFK Zero Folgore - Stonewashed VG-10 & Black Anticorodal - knife
The BFK Zero FOLGORE is an operational EDC project developed in collaboration with the “Folgore” Parachute Brigade, designed for continuous professional use where there is no room for error and every component must perform predictably.
The 3mm VG10 stainless steel blade is engineered to offer a true balance between edge retention, durability, and control, without unnecessary extremes. It features a geometry geared toward intensive daily use, designed to perform rather than be preserved. The construction combines an aluminum handle with steel liners, creating a rigid frame with tight tolerances and consistent mechanical response even under stress.
The Crossbar Lock system ensures safety and reliability at every stage of operation, while maintaining fully ambidextrous handling. Internal bearings ensure a smooth, repeatable opening action, free of jamming, designed to feel natural even without active attention.
The ergonomics are designed for extended carry: the compact profile reduces bulk without compromising the grip, while the ambidextrous clip allows for discreet and customizable carry. The weight remains low for the category, with a balanced distribution that does not feel fragile.
The BFK Zero FOLGORE is a military folding knife conceived as a professional everyday carry tool. It is not designed to be displayed, but to be used. Compact, reliable, efficient
Intended use: Tactical / EDC

More than just a damask, Coreless steel made by Japanese Takefu Steel comes with over 70 layers of VG10 and VG2 stainless steel welded, forged and coated between them so that you can form a lightweight, slim and durable blade with a spectacular damask outer pattern.
The peculiarity of Coreless steel, unlike conventional rolled steel or Japanese San-Mai, is that it does not have a hard core steel that is used for the cutting edge but has both the VG10 and VG2 steels arranged to form the cutting edge so alternating and sequential to each other.
This particular construction gives the blade - compared to the two steels that make it, individually taken - greater resistance to oxidation, higher surface hardness (up to 61.5HRC), 25% more than cutting capacity, 25% more than the wire hold capacity and 25% more resilience making the blade more robust and less subject to breakage.
Thanks to this latest steel, Takefu Steel has been rewarded on Japanese territory for research and development and innovation in the cutting-edge landscape. Coreless steel has already been chosen by major brands such as Kai and Mcusta Zanmai who since 2017 proposed it on their top productions of professional kitchen knives.
