Trivisa Otter Ultra-B JM14U-B-M M390 Blade Titanium Handle Crossbar Lock Folding Knife

Designed for everyday carry and outdoor tasks, the Trivisa Otter Ultra-B JM14U-B-M pairs a 2.99-inch drop-point M390 stainless-steel blade with a lightweight titanium handle. Its black stonewashed finish gives the blade a subdued look, while the crossbar lock secures it open during use. A ceramic ball-bearing pivot supports smooth, controlled deployment. Measuring 6.84 inches overall and weighing just 3.39 ounces, this compact folder is easy to carry in a pocket or pack. The blade is rated at 60±2 HRC for edge retention and wear resistance; its high hardness may require diamond abrasives for sharpening and careful handling to reduce chipping risk. Suitable for everyday carry, hiking, camping, fishing, and hunting, this versatile knife brings premium materials and practical dimensions to outdoor adventures.

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.
