Its 2.54-inch M390 stainless-steel blade features a stonewashed finish and a hardness rating of 60±2 HRC. M390 is valued for wear resistance, corrosion resistance, and long-lasting edge retention; its high hardness can make sharpening more demanding, and heavy lateral stress may increase chipping risk. A ceramic ball-bearing pivot supports smooth opening, while the crossbar lock secures the blade during use. Measuring 5.74 inches overall and weighing just 2.04 ounces, this lightweight folder is easy to carry. Designed by the TRIVISA team, it suits everyday tasks and outdoor activities, offering practical versatility for hiking, camping, fishing, and hunting.\u003c\/p\u003e\n\u003ch2 class=\"product-title\"\u003e\u003cstrong\u003eM390 Blade Introduction\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/edcmall.cn\/collections\/m390\"\u003eM390\u003c\/a\u003e 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.\u003c\/p\u003e\n\u003ch2 class=\"MsoNormal\"\u003e\n\u003cspan\u003e\u003c\/span\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\n\u003c\/h2\u003e\n\u003cp\u003eDesigner:TRIVISA team\u003cbr\u003eStyle: Wharncliffe\u003cbr\u003eBlade Material:M390 steel\u003cbr\u003eBlade Finished: Stonewash\u003cbr\u003eHandle Material:Copper Carbon Fiber\u003cbr\u003eLock Style:Crossbar lock\u003cbr\u003eHardness:60±2HRC\u003cbr\u003eBearing:Ceramic ball bearing\u003c\/p\u003e\n\u003cp\u003eSize:\u003cbr\u003eOverall length-5.74\"(147mm)\u003cbr\u003eBlade length-2.54\" (64.5mm)\u003cbr\u003eClosed length-3.2\"(8.28mm)\u003cbr\u003eBlade width-0.9''(23mm)\u003cbr\u003eBlade thickness-0.12''(3mm)\u003cbr\u003eNet Weight:2.04oz(57.9g)\u003c\/p\u003e\n\u003cp\u003eUsage:Outdoor survival,EDC,hunting,fishing, hiking and camping\u003c\/p\u003e\n\u003ch2\u003eTrivisa Sloth Ultra-PC - Stonewashed M390 Wharncliffe with a Copper Carbon Fiber Handle\u003c\/h2\u003e\n\u003cp\u003eThe Trivisa Sloth Ultra-PC pairs a 2.54 inch \u003ca href=\"\/es\/collections\/m390\"\u003eM390\u003c\/a\u003e Wharncliffe in stonewashed with a copper carbon fiber handle, a \u003ca href=\"\/es\/collections\/crossbar-lock-knives\"\u003ecrossbar lock\u003c\/a\u003e and ceramic bearings at just 57.9 g (2.04 oz).
