{"product_id":"fractured-shield-aluminum-knuckle-duster","title":"Fractured Shield Aluminum Knuckle Duster","description":"\u003cp\u003eThe Fractured Shield Knuckle Duster is a precision-machined knuckle duster built around a strong symbolic centerpiece: a heraldic shield engraved into the palm plate, woven through with a web of radiating cracks — as if the shield itself has been struck and the fractures are spreading outward across the metal. It is CNC-milled from a single block of aerospace-grade 6061-T6 aluminum and finished in a matte anodized olive-drab color — a muted, tactical green that does not pick up fingerprints and keeps its color.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003eMaterial: 6061-T6 aluminum alloy\u003cbr\u003eFinish: Anodized matte olive drab\u003cbr\u003eSize: 116mm × 66mm × 15mm\u003cbr\u003eFinger holes: 4 holes, approx. 25mm × 29mm each\u003cbr\u003eWeight: about 132g\u003cbr\u003eType: Four-finger EDC knuckle duster\u003cbr\u003eDesign: Laser-engraved fractured shield emblem with radiating crack pattern on the palm plate; scalloped outer silhouette; fully chamfered edges\u003c\/p\u003e\n\u003ch3\u003eLaser-Engraved Fractured Shield\u003c\/h3\u003e\n\u003cp\u003eThe signature detail of this knuckle duster sits on the palm side. At the center sits a classic heraldic shield with a flat top and a pointed bottom; inside the shield, interlocking angular lines form a fragmented geometric pattern like broken plate. From the shield's edge, irregular crack lines branch outward in every direction across the palm plate, giving the impression of an impact frozen in metal. The engraving is shallow, crisp and uniform — it adds texture and character without affecting the smooth, comfortable feel of the plate against the hand.\u003c\/p\u003e\n\u003ch3\u003eAerospace-Grade 6061-T6 Aluminum\u003c\/h3\u003e\n\u003cp\u003e6061-T6 is the alloy used in aircraft frames, bicycle components and tactical gear — high strength-to-weight ratio, excellent corrosion resistance and good machinability. The piece is CNC-milled from a single solid billet, giving it a smooth, continuous form with no welds, seams or joints. Unlike cast zinc alloy, the aluminum surface takes anodizing beautifully, so the olive-drab color is bonded to the metal rather than sitting on top of it.\u003c\/p\u003e\n\u003ch3\u003eAnodized Olive-Drab Finish\u003c\/h3\u003e\n\u003cp\u003eThe matte olive-drab color of this knuckle duster is produced by anodizing — an electrochemical process that converts the surface layer of the aluminum into a durable, corrosion-resistant oxide. The result:\u003cbr\u003eA uniform matte finish that does not show fingerprints or smudges.\u003cbr\u003eLong-term resistance to corrosion and oxidation, even in humid environments.\u003c\/p\u003e\n\u003ch3\u003eSoft, Continuous Scalloped Silhouette\u003c\/h3\u003e\n\u003cp\u003eThis knuckle duster takes a noticeably different shape from classic angular models:\u003cbr\u003eFour evenly sized finger holes (approx. 25mm × 29mm), arranged in a straight row to fit all four fingers comfortably.\u003cbr\u003eThe outer edge follows a smooth, continuous scalloped \/ wave-like curve — each hole is framed by a soft rounded bulge, and the entire perimeter flows without sharp corners or lugs.\u003cbr\u003eAll edges — the outer rim and every finger-hole edge — are fully chamfered with generous radii, so the piece feels rounded and comfortable against the skin.\u003cbr\u003eThe palm plate is slightly domed, so it rests naturally against the hand without digging in.\u003c\/p\u003e\n\u003ch3\u003eLightweight but Substantial\u003c\/h3\u003e\n\u003cp\u003eAt 116mm × 66mm × 15mm and roughly 132g, this four-finger knuckle duster is a comfortable carry-weight: solid enough to feel like a real piece of machined hardware, but light enough to live in a pocket or small bag without weighing you down. The 6061-T6 aluminum gives it rigidity without the heavy mass of a brass or steel duster.\u003c\/p\u003e\n\u003ch3\u003eNovelty EDC Collectible \u0026amp; Desk Paperweight\u003c\/h3\u003e\n\u003cp\u003eThis item is sold as a novelty collectible knuckle duster, desk ornament and lightweight EDC paperweight — a distinctive piece of CNC-machined metalwork for display cabinets, tabletop use and collectors who like a modern, emblem-led look compared to classic heavy brass knuckles.\u003c\/p\u003e","brand":"BRASSKNUCKLE","offers":[{"title":"Default Title","offer_id":71535430664445,"sku":null,"price":48.17,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/4254\/6685\/files\/FracturedShieldKnuckleDuster_11.jpg?v=1791874464","url":"https:\/\/brassknuckle.co.uk\/fr\/products\/fractured-shield-aluminum-knuckle-duster","provider":"Brass Knuckle","version":"1.0","type":"link"}
