Borka Blades x Marfione Custom SBTF 1-of-1 – Star Grind Tanto – Frag Titanium – Tritium Inlay

Elite 1-of-1 Collaboration: The Borka x Marfione SBTF

The Borka Blades x Marfione Custom SBTF is a rare masterpiece of tactical engineering, born from the storied 2022 collaboration between two of the industry’s most legendary makers. This specific Borka Blades x Marfione Custom SBTF is a unique One-of-One build, distinguished by its hand-ground Star Grind Tanto blade. This complex, multi-faceted grind showcases Anthony Marfione’s world-class grinding expertise, providing a signature geometric aesthetic and incredible tip strength that is synonymous with elite custom cutlery.

The chassis of this Borka Blades x Marfione Custom SBTF is crafted from heavy-duty titanium with a precision Frag Pattern texture, offering a superior grip and a rugged, industrial look. A standout collector feature is the integrated Tritium vial inset into the butt of the handle, providing an “always-on” glow for low-light orientation. Every component, from the custom-milled pocket clip to the complex blade geometry, reflects a level of detail that only a 1-of-1 Marfione collaboration can deliver.

Collector Rarity: Star Grind and Frag Titanium Provenance

Owning a Borka Blades x Marfione Custom SBTF in this 1-of-1 configuration is a crowning achievement for any high-end collection. This preowned piece is in excellent condition, having been meticulously curated since its 2022 release. The provenance is impeccable, including the original Marfione Custom box, zippered pouch, and the highly coveted Certificate of Authenticity (COA) hand-signed by both Sebastijan Berenji and Anthony Marfione, explicitly verifying its unique status.

As a high-value asset, the Borka Blades x Marfione Custom SBTF remains one of the most liquid and sought-after models in the secondary market. The combination of the Star Grind, Frag Titanium, and the factory-installed Tritium vial makes this variant exponentially more difficult to source than standard collaboration models.
