The Trivisa Scarab-B JM09-B-M combines a compact profile with premium materials for everyday carry and outdoor use. Its 2.99-inch M390 stainless steel blade features a black stonewashed PVD finish and a swedge design. Known for wear and corrosion resistance, M390 is suited to extended use and edge retention; its high hardness may make sharpening more demanding. A titanium handle keeps the knife lightweight at 2.36 ounces, while the crossbar lock secures the blade open. Ceramic ball bearings support smooth opening. Measuring 6.79 inches overall and 3.8 inches when closed, this folding knife is easy to carry and handle. Designed by the TRIVISA Team, it is a practical choice for hiking, camping, fishing, hunting, and everyday tasks.

M390 Blade Introduction

M390 is an advanced powder-metallurgical stainless steel utilizing high chromium and vanadium content to deliver exceptional wear resistance and industry-leading corrosion resilience. It excels at retaining a razor-sharp edge under prolonged use; however, this extreme hardness renders the blade notably difficult to sharpen or reprofile without diamond abrasives. Additionally, its fine microstructure, while offering superior edge stability, sacrifices some structural toughness and may be more prone to chipping under heavy lateral stress.
