Its 2.99-inch sheepfoot blade is made from 14C28N stainless steel, a low-maintenance choice valued for corrosion resistance and easy sharpening. A sandblasted finish completes the blade, while the lightweight PEI handle and ceramic ball bearings support comfortable handling and smooth opening. The crossbar lock secures the blade during use. Measuring 6.7 inches overall and 3.7 inches closed, this folding knife weighs just 2.39 ounces for convenient carry. The blade is 0.11 inches thick, with a stated hardness of 60±2 HRC. Suitable for everyday carry and outdoor activities such as hiking, camping, fishing, and hunting, it offers a practical, portable design.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003e14C28N Blade Introduction\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/edcmall.cn\/collections\/14c28n\"\u003e14C28N\u003c\/a\u003e is a high-value budget-to-midrange stainless steel that excels in corrosion resistance and ease of sharpening, making it a low-maintenance workhorse for EDC and wet environments, but it falls short of premium steels in edge retention and requires more frequent touch-ups when cutting highly abrasive materials like cardboard.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eDesigner: TRIVISA team\u003cbr\u003eStyle: Sheepfoot\u003cbr\u003eBlade Material：14C28N steel\u003cbr\u003eBlade Finished：Sandblasting\u003cbr\u003eHandle Material: PEI\u003cbr\u003eLock Style:Crossbar lock\u003cbr\u003eHardness: 60±2HRC\u003cbr\u003eBearing: Ceramic ball bearing\u003c\/p\u003e\n\u003cp\u003eSize:\u003cbr\u003eOverall length-6.7\"(171mm)\u003cbr\u003eBlade length-2.99\" (76mm)\u003cbr\u003eClosed length-3.7\"(95mm)\u003cbr\u003eBlade width-1.16''（29mm)\u003cbr\u003eBlade thickness-0.11''(3mm)\u003cbr\u003eNet Weight:2.39oz(68g)\u003cbr\u003eUsage:Outdoor survival,EDC,hunting,fishing, hiking and camping\u003c\/p\u003e\n\u003ch2\u003eTrivisa Batwing-YP - Sandblast 14C28N Sheepfoot on a Translucent Yellow PEI Handle\u003c\/h2\u003e\n\u003cp\u003eThe \u003ca href=\"\/collections\/trivisa-knives\"\u003eTrivisa\u003c\/a\u003e Batwing-YP JM10S-YP-14 pairs a sandblast \u003ca href=\"\/collections\/14c28n\"\u003e14C28N\u003c\/a\u003e sheepfoot with translucent yellow PEI scales, opened by thumb hole and locked by an ambidextrous \u003ca href=\"\/collections\/crossbar-lock-knives\"\u003ecrossbar lock\u003c\/a\u003e at just 68 g.

PEI (polyetherimide) is an engineering polymer that is rigid, heat-resistant and chemically inert, and here it is translucent, so the hardware glows through the yellow scales.
