Bestech Blind Fury BT2303F – 3.62" M390 Black Stonewash, Black Stonewash Titanium + Blue Marble Inlay, Frame Lock

The Bestech Blind Fury BT2303F is a striking full-size titanium frame lock folding knife designed by Kombou and available at Going Gear, your authorized Bestech dealer. Built around a 3.62-inch M390 blade in black stonewash, the BT2303F features a matching black stonewash titanium handle with blue marble carbon fiber inlays — accented by a signature blue titanium pivot collar that delivers a bold pop of color against the all-black design. Ceramic ball bearings ensure a smooth, precise flipper deployment every time.

The BT2303F is one of the most visually cohesive knives in the Bestech lineup: the black stonewash finish runs across both blade and handle for a seamless, monochromatic base, while the blue marble inlays and blue pivot collar provide deliberate, elegant contrast. At 114 grams and 4.66 inches closed, the Bestech Blind Fury BT2303F is a full-size premium folder equally at home on a collector's display or in a daily carry pocket.

Key Features

• M390 Blade with Black Stonewash Finish — The Bestech Blind Fury BT2303F uses M390 stainless steel from Böhler at 60–62 HRC, finished in black stonewash for outstanding corrosion and wear resistance with a tactical matte appearance. M390 delivers exceptional edge retention and easy maintenance for serious everyday carry use.
• Blue Titanium Pivot Collar — The BT2303F's most defining detail: a blue anodized titanium pivot collar that punctuates the all-black stonewash design with a precise accent of color. This detail is Kombou's design signature on the Blind Fury and makes the BT2303F immediately recognizable among Bestech's titanium folder lineup.
• Blue Marble Carbon Fiber Inlay Handle — The Bestech Blind Fury BT2303F features blue-toned marble carbon fiber inlays in the black stonewash titanium handle — a colorway that complements the blue pivot accent and creates a premium, collector-quality aesthetic throughout the knife.
• Unified Black Stonewash Finish — Unlike many production knives that mix finish treatments, the BT2303F applies the same black stonewash to both the M390 blade and the titanium handle scales and clip, creating a visually unified design where the blue accents stand out all the more effectively.
• Titanium Frame Lock — The Bestech Blind Fury BT2303F uses a titanium frame lock for a strong, reliable lockup. The frame lock is integrated into the titanium handle chassis and engages the blade tang solidly when opened.
• Ceramic Ball Bearings — The BT2303F deploys on ceramic ball bearings for an exceptionally smooth one-handed flipper action with superior corrosion resistance over steel bearings.
• Designed by Kombou — The Blind Fury is a Bestech collaboration with Kombou, a custom knife designer known for cohesive, detail-driven designs where accent colors and finish choices are precisely considered. The BT2303F is one of Kombou's most recognized production pieces.
• Full Titanium Furniture — The Bestech Blind Fury BT2303F's clip and backspacer are both titanium with matching black stonewash, maintaining the knife's consistent finish throughout every component.

Who Is the Bestech Blind Fury BT2303F For?

The Bestech Blind Fury BT2303F appeals to three distinct buyers. Collectors will be drawn to the blue pivot collar and blue marble inlay — details that show exactly how much thought Kombou put into making the BT2303F a coherent design object, not just a knife. EDC users who prefer a full-size folder will appreciate the 3.62-inch M390 blade, smooth ceramic bearings, and the reliable titanium frame lock in a 114-gram package. And fans of all-black builds with color accents will find the Blind Fury BT2303F one of the most refined executions of that aesthetic in production knife making. Available at Going Gear, an authorized Bestech dealer with worldwide shipping.

Frequently Asked Questions

What steel does the Bestech Blind Fury BT2303F use?

The Bestech Blind Fury BT2303F uses M390 stainless steel from Böhler, heat treated to 60–62 HRC. M390 is one of the finest production blade steels available, offering exceptional edge retention, outstanding corrosion resistance, and excellent wear resistance. The black stonewash finish on the BT2303F's M390 blade adds further corrosion protection and hides surface marks from daily carry.

What makes the blue pivot collar on the BT2303F special?

The blue titanium pivot collar on the Bestech Blind Fury BT2303F is the knife's defining design detail — a precisely placed accent that creates intentional contrast against the all-black stonewash handle and blade. The pivot collar is anodized titanium, which achieves its blue color through an electrochemical oxidation process that adds no coating or paint — the color is inherent to the titanium oxide layer and is extremely durable. It directly echoes the blue marble inlay in the handle scales, tying the design together.

What is the difference between the blue marble inlay on the BT2303F vs the marble inlay on the BT2405B Spear Phisher?

Both the Bestech Blind Fury BT2303F and the Bestech Spear Phisher BT2405B feature marble carbon fiber handle inlays, but with distinct colorways. The BT2303F uses blue-toned marble that coordinates with its blue titanium pivot collar and black stonewash handle — a cool, monochromatic palette. The BT2405B uses white/grey marble on a white bead blast titanium handle — a lighter, warmer aesthetic. The BT2303F's darker, moodier colorway makes it a better fit for buyers who prefer all-black EDC builds.

Who designed the Bestech Blind Fury?

The Bestech Blind Fury was designed by Kombou, a custom knife designer known for cohesive, detail-driven design work where every finish choice and accent color is intentional. The BT2303F is one of Kombou's most recognized production collaborations with Bestech — the blue pivot collar and blue marble combination is a Kombou design signature that makes the Blind Fury instantly identifiable.

How large is the Bestech Blind Fury BT2303F?

The Bestech Blind Fury BT2303F has a 3.62-inch (91.9mm) blade with an 8.28-inch (210.3mm) overall open length and 4.66-inch (118.3mm) closed length. At 114 grams, it is a full-size premium folder — larger than compact EDC models like the BT2401C Bruv (2.95") or BT2308B Nyxie 3 (2.99"), but lighter than the full-size Cetus BT2304B (176g).

Is the Bestech Blind Fury BT2303F worth the price?

Yes — the Bestech Blind Fury BT2303F delivers excellent value for a premium full-size titanium frame lock folder. You get M390 blade steel, a thoughtfully designed dual-accent colorway (blue pivot + blue marble), ceramic bearings, and a unified black stonewash finish across all components — at a price well below what comparable custom or semi-custom knives would cost. For collectors and EDC users who want a distinctive M390 titanium folder, the BT2303F is a strong buy at Going Gear.

Bestech Blind Fury BT2303F vs Bestech Cetus BT2304B — which should I buy?

Both the Bestech Blind Fury BT2303F and the Bestech Cetus BT2304B are full-size premium titanium folders with M390 steel and black-dominant colorways, but they differ significantly in design character. The BT2303F (3.62", 114g) is a frame lock with blue marble inlays and a refined, cohesive design by Kombou — built for daily carry with collector appeal. The BT2304B (3.94", 176g) is a heavier bar lock with canvas micarta inlays and an aggressive Poltergeistworks design — built for hard use and maximum visual presence. Choose the BT2303F for an elegant everyday carry; choose the BT2304B for a larger, tougher working knife.

What lock does the Bestech Blind Fury BT2303F use?

The Bestech Blind Fury BT2303F uses a titanium frame lock. The frame lock engages a section of the titanium handle frame into the blade's tang when opened, providing a strong, wobble-free lockup for confident use. The frame lock on the BT2303F is integrated cleanly into the black stonewash handle without disrupting the knife's visual consistency.

Where can I buy the Bestech Blind Fury BT2303F?

The Bestech Blind Fury BT2303F is available at Going Gear, an authorized Bestech Knives dealer. Going Gear stocks a wide selection of Bestech titanium frame lock folders including other M390 models like the Bestech Spear Phisher BT2405B and the Bestech Cetus BT2304B.

What is the best Bestech knife with a blue accent?

Its blue titanium pivot collar and blue marble carbon fiber inlays create the most deliberate and refined blue color story in Bestech's titanium production lineup.
