Benchmade 275SGY-1 Adamas Tactical Folding Knife — CPM-CruWear Serrated Tungsten Gray, Black G10 Handle

The Adamas — with bite. The Benchmade 275SGY-1 Adamas is the partially serrated variant of Shane Sibert's legendary tank-like tactical folder, purpose-built for operators and hard-use professionals who need the aggressive cutting capability of a serrated edge alongside the proven platform that has made the Adamas one of the most trusted tactical folders in Benchmade's lineup. Same bombproof construction. Same CPM-CruWear performance. A whole new capability when it matters most.

When wet rope, seatbelts, webbing, netting, and tough cordage resist a plain edge, the serrated section of the 275SGY-1 bites through with authority. The plain section near the tip retains the precision needed for detail work, field dressing, and everyday utility tasks. Two distinct performance profiles in one blade — exactly what first responders, military personnel, and serious outdoor users need in a single knife they can carry every day.

The 3.78" drop-point blade is crafted from CPM-CruWear tool steel — heat treated to 63-65 HRC for extreme edge retention, outstanding toughness, and wear resistance that far surpasses traditional stainless steels. The Tungsten Gray finish keeps the blade non-reflective and purpose-driven. A top swedge and blade fullers reduce weight without sacrificing strength, while heavy spine jimping and a notched thumb ramp give your thumb a secure, fatigue-free purchase for maximum blade control under pressure. Dual ambidextrous thumb studs provide fast, confident one-handed deployment from either side.

The black G10 handle scales feature milled grooves and holes throughout to reduce weight while maintaining full structural integrity, with aggressive texturing that stays confident in wet, cold, and high-stress conditions. Steel liners provide full structural strength. The AXIS Lock mechanism delivers smooth, ambidextrous one-handed operation and rock-solid lockup. A reversible deep-carry tip-up pocket clip, lanyard hole, and MOLLE compatibility make this knife as adaptable to tactical kit as it is to daily carry. A black ballistic nylon sheath is included. Proudly made in the USA and backed by Benchmade's LifeSharp lifetime sharpening service.
