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.
