Bestech Buwaya BT2203D – 3.54" M390 Black Stonewash, Retro Green Titanium, Frame Lock

The Bestech Buwaya BT2203D is a full-size, full-titanium premium frame lock folder designed by KOMBOU and available at Going Gear, your authorized Bestech dealer. The BT2203D pairs a 3.54-inch M390 blade in black stonewash with a pure retro green titanium handle — no inlays, no composite materials, just machined titanium in a warm, earthy military green that is unlike anything else in Bestech's current titanium lineup. Ceramic ball bearings deliver smooth, fast deployment, and the frame lock provides secure, direct lockup that full-titanium construction makes possible at this level.

Buwaya is the Filipino/Tagalog word for crocodile — and the BT2203D earns the name. At 3.54 inches of blade, 150 grams, and 4mm blade stock, it is the most substantial folding knife in this Bestech titanium series: largest blade, most blade stock, heaviest overall weight. The black stonewash M390 finish is the most aggressive in the lineup — textured to hide micro-scratches and fingerprints, non-reflective in direct light, and built around M390 exceptional edge retention and corrosion resistance at 60-62 HRC. This is the Bestech for buyers who want a full-size, all-titanium, maximum-capability M390 folder at their authorized dealer price point.

Key Features

• 3.54-Inch M390 Blade in Black Stonewash — The Bestech Buwaya BT2203D carries the longest M390 blade in this Bestech titanium series at 3.54 inches (90mm) with a blade stock of 4.0mm — the thickest in the lineup. M390 stainless steel from Bohler delivers outstanding edge retention, superior corrosion resistance, and excellent wear resistance at 60-62 HRC. The black stonewash finish provides a non-reflective, tactile surface that reduces micro-scratch appearance and daily carry wear. The overall knife is 8.19 inches deployed, with a 4.64-inch closed length that makes it ideal as a dedicated work or outdoors carry rather than an ultra-compact EDC.
• Retro Green Pure Titanium Handle — The BT2203D handle is machined entirely from titanium in Bestech Retro Green — a warm, olive-toned military green with earthy, vintage character that stands apart from the grey, blue, and black titanium handles across the rest of the Bestech lineup. There are no micarta inlays, carbon fiber panels, or composite overlays — the Buwaya is pure titanium on both sides of the handle, giving it a solid, monolithic feel in hand and a distinctive color appearance.
• Full Titanium Frame Lock Construction — The BT2203D uses a frame lock built into the titanium handle — a section of the handle frame that springs laterally into the blade path on opening, providing direct metal-on-metal blade contact. Frame locks on full-titanium handles are preferred by many users over liner locks for the larger contact surface and simplicity of one-piece handle construction. The Buwaya 150g weight reflects this solid build.
• KOMBOU Designer Collaboration — The Bestech Buwaya BT2203D is a collaboration with KOMBOU, a knife designer known for bold, large-format folding knife designs with strong visual identities and purposeful ergonomics. The Buwaya name, retro green colorway, and full-titanium construction reflect KOMBOU design philosophy — knives that make a clear statement and perform at the level their aesthetics suggest.
• Ceramic Ball Bearings — The BT2203D deploys on ceramic ball bearings, providing smooth, fast, consistent one-handed opening that keeps pace with the knife size and build quality. Ceramic bearings are corrosion-resistant and low-maintenance.
• Heaviest and Most Substantial in the Series — At 150 grams and 4mm blade stock, the Bestech Buwaya BT2203D is the heaviest and most solidly built knife in this Bestech series — appropriate for buyers who want a full-size, purpose-built M390 workhorse for outdoor work, camping, hiking, and demanding cutting tasks.

Who Is the Bestech Buwaya BT2203D For?

Frequently Asked Questions

What steel does the Bestech Buwaya BT2203D use?

The Bestech Buwaya BT2203D uses M390 stainless steel from Bohler, heat treated to 60-62 HRC with a black stonewash finish. M390 delivers exceptional edge retention, superior corrosion resistance, and excellent wear resistance — among the best-performing stainless steels in production folding knives at any price point. The black stonewash finish adds a non-reflective, scratch-hiding texture that makes M390 performance more practical in daily use.

What does the name Buwaya mean?

Buwaya (pronounced boo-WI-ya) is the Filipino and Tagalog word for crocodile. The name reflects the Bestech Buwaya BT2203D aggressive, full-size character — a large, solid, purpose-built folder with the most substantial blade in the Bestech titanium series. The retro green titanium colorway complements the name with an earthy, natural aesthetic that reads differently from the tactical blacks and steels of more conventional production knives.

What is the Retro Green colorway on the BT2203D?

The Retro Green on the Bestech Buwaya BT2203D is a warm, olive-toned military green titanium finish — earthy and vintage in character rather than bright or saturated. It is machined directly into the full titanium handle with no inlays or overlays. The color stands apart from the grey, blue, and black titanium handles in the rest of the Bestech lineup and is genuinely rare among production premium folders — making the BT2203D one of the most distinctive-looking knives in the series.

Bestech Buwaya BT2203D vs Bestech Nyxie BT2209C — which should I buy?

Both the Bestech Buwaya BT2203D and the Bestech Nyxie BT2209C are larger premium titanium folders with serious blade steel, but they differ in blade length, steel, weight, and construction. The BT2203D Buwaya (3.54 inch M390, black stonewash, pure retro green titanium, 150g) is the larger, heavier, more aggressive option — pure titanium with no inlays, the longer blade, and the darker, more tactical finish. The BT2209C Nyxie (3.43 inch S35VN, stonewash plus satin, grey titanium with carbon fiber) is more refined and slightly smaller. Choose the Buwaya for maximum blade length and pure titanium; choose the Nyxie for a more refined aesthetic and lighter carry.

The BT2203D is larger, heavier, and more tactical in finish; the BT2206A is lighter with a satin blade and distinctive bar lock and thumb disk deployment combination. Choose the Buwaya for maximum blade length; choose the Mothus for a unique lock mechanism and satin M390 with blue titanium.

Is the Bestech Buwaya BT2203D worth the price?
