Bestech SENU BT2601D CPM-S90V Blade Titanium Handle Frame Lock Folding Knife

The Bestech SENU BT2601D features a CPM-S90V blade, a premium martensitic stainless steel celebrated for exceptional wear resistance and edge retention from its high vanadium carbide content. This advanced steel demands specialized sharpening tools but delivers unmatched cutting performance. The titanium frame with camo carbon inlays and black PVD finish provides durability and elegance. Multiple deployment options—flipper, front flipper, and thumb hole—offer versatile carry and access. At 108g with ceramic ball bearings, it balances lightweight efficiency with smooth operation. The frame lock ensures secure blade control. Designed by Grzegorz Grabarski, this 3.48" blade knife excels for precision cutting tasks where edge retention matters most, though heavy impacts should be avoided due to the carbide-dense steel's reduced toughness.

CPM-S90V Blade Introduction

CPM-S90V is a premium, high-alloy martensitic stainless steel renowned for its exceptional wear resistance and unparalleled edge retention, owing to a high volume of hard vanadium carbides. However, this extreme wear resistance makes it notoriously difficult to sharpen and machine, requiring specialized abrasive tools like diamond or cubic boron nitride. Additionally, while highly corrosion-resistant due to its chromium content, its high carbide density reduces its overall toughness, making it susceptible to chipping if subjected to heavy impacts or prying tasks.
