Its 20 mm bead-blasted blade is made from 14C28N stainless steel, with a hardness of 58–61 HRC. Known for corrosion resistance and easy sharpening, this steel offers practical, low-maintenance performance, though abrasive cutting may require more frequent edge touch-ups. The purple titanium handle features a tortoise pattern, adding distinctive character while keeping the knife lightweight at 24.5 g. Measuring 53 mm overall and 33 mm closed, it fits easily into a pocket or small carry setup. The blade is 2.5 mm thick, and the button lock provides convenient operation. Made in China, the Turtle BM20H balances compact proportions with useful everyday functionality for users seeking a small folding knife.\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\u003cul\u003e\n\u003cli\u003eBlade Length: 0.79\"(20mm)\u003c\/li\u003e\n\u003cli\u003eClosed length: 1.30\"(33mm)\u003c\/li\u003e\n\u003cli\u003eOverall Length: 2.09\"(53mm)\u003c\/li\u003e\n\u003cli\u003eBlade Thickness: 0.10\"(2.5mm)\u003c\/li\u003e\n\u003cli\u003eBlade Material: 14C28N\u003c\/li\u003e\n\u003cli\u003eBlade Finish: Bead Blast\u003c\/li\u003e\n\u003cli\u003eBlade Hardness: 58-61 HRC\u003c\/li\u003e\n\u003cli\u003eHandle Material: Purple Titanium, with Tortoise Pattern\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLocking Mechanism: Button Lock\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWeight: 0.86 oz (24.5 g)\u003c\/li\u003e\n\u003cli\u003eMade in China\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBestechman Turtle BM20H - Coin-Shaped Purple Titanium Keychain Knife\u003c\/h2\u003e\n\u003cp\u003eThe \u003ca href=\"\/collections\/bestechman-knives\"\u003eBestechman\u003c\/a\u003e \u003ca href=\"\/collections\/bestechman-turtle\"\u003eTurtle\u003c\/a\u003e BM20H folds into a purple titanium coin just 1.30 inches across: a 20 mm \u003ca href=\"\/collections\/14c28n\"\u003e14C28N\u003c\/a\u003e Wharncliffe blade, a \u003ca href=\"\/collections\/button-lock-knives\"\u003ebutton lock\u003c\/a\u003e and a thumb-hole opener at 24.5 g (0.86 oz).
