The Bestech Excentric BT2412B is a large-format, premium folding knife built for users who want full-size cutting performance in a refined titanium package. Designed through a collaboration between Grzegorz Grabarski and TNT Knives, the Excentric features a 3.882" M390 blade with a black stonewash finish matched to a black stonewash titanium handle — a unified all-black aesthetic across every surface of the knife.
At 9.094" overall, the BT2412B is a purposeful full-size knife for users who prioritize blade length and cutting capability. The 3.882" M390 blade is thick at 0.157" (4.0mm), providing a sturdy, robust geometry suited for hard use and demanding tasks. M390 steel — produced by Bohler-Uddeholm using powder metallurgy — delivers outstanding edge retention and excellent corrosion resistance, heat treated here to 59–61 HRC for a balance of edge-holding performance and toughness.
The black stonewash finish on both blade and handle is one of the Excentric's defining characteristics. Stonewash texturing hides use marks and scratches, resists showing fingerprints, and provides a uniform matte appearance that keeps the knife looking sharp in the field. Combined with the titanium handle's inherent corrosion resistance, the BT2412B is a genuinely low-maintenance large-format knife.

Frequently Asked Questions
What steel is the Bestech Excentric BT2412B made from?
The Bestech Excentric BT2412B uses M390 steel by Bohler-Uddeholm, a high-performance powder metallurgy stainless steel widely regarded as one of the best production knife steels for edge retention and corrosion resistance. The Excentric's M390 is heat treated to 59–61 HRC, delivering a reliable balance of sharpness, edge-holding ability, and toughness for a large-format knife.
Is 59–61 HRC good for the Bestech Excentric BT2412B's M390 steel?
Yes. While M390 can be pushed to higher hardness values, a heat treatment of 59–61 HRC for a large, thick-bladed knife like the Bestech Excentric BT2412B is a deliberate choice that prioritizes toughness and impact resistance alongside edge retention. The thicker 4.0mm spine means the Excentric sees more lateral and hard-use stress than a thinner EDC blade, and a slightly lower hardness provides better resistance to chipping under those conditions without meaningfully sacrificing cutting performance.
What is the black stonewash finish on the Bestech Excentric BT2412B?
Black stonewash combines a dark coating (typically applied via PVD or oxide treatment) with a stonewash tumbling process that creates a matte, textured surface with micro-abrasion patterns. The result is a finish that hides scratches and fingerprints better than polished or plain finishes, reduces glare, and gives the Bestech Excentric BT2412B its distinctive unified all-black appearance. It is one of the most practical and durable blade and handle finishes available for hard-use knives.
How big is the Bestech Excentric BT2412B?
The Bestech Excentric BT2412B measures 9.094" (231mm) overall when open, with a 3.882" (98.6mm) blade and a closed length of 5.212" (132.4mm). It is a full-size large-format folding knife — larger than most EDC folders. For users wanting maximum blade capability in a folding knife, the BT2412B delivers; for compact carry, the BT2501B Constellation (3.055") or BT2603D Mini Taipan (3.25") are better fits.
How does the M390 on the Bestech Excentric BT2412B compare to MagnaCut for a large knife?
Both are premium powder metallurgy stainless steels with excellent corrosion resistance and edge retention. MagnaCut generally offers slightly better toughness and comparable or better edge retention at higher hardness values. M390 at 59–61 HRC (as on the Bestech Excentric BT2412B) prioritizes a toughness-focused heat treatment appropriate for a thicker, more robustly used knife. For a large blade with a 4.0mm spine, M390 at this hardness is an excellent and well-matched choice.
Who designed the Bestech Excentric BT2412B?
The Bestech Excentric BT2412B was designed through a collaboration between Grzegorz Grabarski, a respected Polish custom knife designer known for ergonomic titanium folders, and TNT Knives, a knife design team known for bold, large-format designs. The Excentric reflects both influences: Grabarski's ergonomic geometry and TNT's preference for substantial, full-size knives with a strong visual presence.
Is the Bestech Excentric BT2412B good for everyday carry?
The Bestech Excentric BT2412B is best suited for users who specifically want a large-format folding knife for demanding EDC, outdoor, or work use. At 5.212" closed and 162 grams, it carries larger and heavier than compact EDC options. Users in states that permit blades up to 4 inches will find it within legal EDC range; always check local regulations. For lighter-carry users, the BT2501B Constellation (73g, 3.055" blade) or BT2503D Taipan (107.5g, 3.73" blade) are better choices.
What lock type does the Bestech Excentric BT2412B use?
The Bestech Excentric BT2412B uses a titanium frame lock. On a knife of this size, the titanium frame lock provides particularly strong lockup — the mass of the titanium handle gives the lockbar excellent contact area and engagement with the blade tang. It is reliable, easy to disengage one-handed, and requires minimal maintenance.
Does the all-black stonewash finish on the Bestech Excentric BT2412B hold up over time?
Yes. Black stonewash is one of the most durable knife finishes available. The stonewash texture naturally hides minor scratches and carry marks that accumulate on any knife. As the finish wears at high-contact points over extended use, the patina adds character rather than looking damaged. The Bestech Excentric BT2412B's underlying titanium handle is naturally corrosion-resistant, and M390's high chromium content keeps the blade resistant to rust even if the surface finish wears.
