At the centre of the palm plate sits a laser-engraved heraldic crest, its surface cut through with angular fracture lines that spread outward like an impact frozen in metal. Part collectible, part everyday carry, entirely machined hardware — the Shattered Crest is the piece that earns a spot on the desk and a place in the pocket.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003eMaterial: 6061-T6 aluminum alloy\u003cbr\u003eFinish: Anodized matte olive drab\u003cbr\u003eDimensions: 116 × 66 × 15 mm\u003cbr\u003eFinger holes: 4 holes, approx. 25 × 29 mm each\u003cbr\u003eWeight: about 132 g\u003cbr\u003eType: Four-finger EDC knuckle duster\u003cbr\u003eDesign: Laser-engraved cracked crest; scalloped silhouette; chamfered edges\u003c\/p\u003e\n\u003ch3\u003eDesign — A Crest Struck and Fractured\u003c\/h3\u003e\n\u003cp\u003eThe signature detail of this knuckle duster is the engraving on the palm side. A classic shield emblem with a flat top and pointed bottom anchors the plate, its interior filled with interlocking angular lines that read like shattered glass or cracked ceramic. From the shield's edge, fine crack lines radiate in every direction. The engraving is shallow, crisp and uniform, adding texture and character to the metal without changing the smooth, comfortable feel against the hand.\u003c\/p\u003e\n\u003ch3\u003eMaterial — One Billet, Zero Joints\u003c\/h3\u003e\n\u003cp\u003eMachined from a single solid billet of aerospace-grade 6061-T6 aluminum, the Shattered Crest is one continuous piece of metal — no welds, no seams, no joins. 6061-T6 is the alloy used in aircraft frames, bicycle components and tactical gear, valued for its high strength-to-weight ratio and strong corrosion resistance. The result is an aluminum knuckle duster with genuine rigidity, without the heavy mass of traditional metal designs.\u003c\/p\u003e\n\u003ch3\u003eFinish — Anodized Olive Drab\u003c\/h3\u003e\n\u003cp\u003eThe muted olive-drab green isn't paint. It comes from anodizing, an electrochemical process that converts the surface layer of the aluminum into a hard, corrosion-resistant oxide. What that means in practice:\u003c\/p\u003e\n\u003cp\u003e- A uniform matte finish that shrugs off fingerprints and smudges\u003cbr\u003e- Long-term resistance to corrosion and oxidation, even in humid environments\u003cbr\u003e- Colour bonded into the metal itself, not a coating sitting on top of it\u003c\/p\u003e\n\u003ch3\u003eFit — Four Fingers, Scalloped Edges\u003c\/h3\u003e\n\u003cp\u003e- Four evenly sized finger holes (approx. 25 × 29 mm) arranged in a straight row for a comfortable four-finger fit\u003cbr\u003e- A soft, wave-like scalloped outer silhouette — each hole framed by a rounded bulge, with no sharp corners or lugs\u003cbr\u003e- Every edge, from the outer rim to each finger hole, fully chamfered with generous radii\u003cbr\u003e- A gently domed palm plate that rests naturally in the hand without digging in\u003c\/p\u003e\n\u003ch3\u003eCarry — Light Enough for a Pocket\u003c\/h3\u003e\n\u003cp\u003eAt 116 × 66 × 15 mm and around 132 g, the Shattered Crest is a comfortable carry weight: solid enough to feel like genuine machined hardware, light enough to live in a pocket or small bag without weighing you down. Use it as an everyday carry piece, a desk paperweight, or a display piece for collectors who prefer a modern, emblem-led look over classic heavy metal designs.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cp\u003eIs the olive-drab colour going to fade? No — the finish is anodized, meaning the colour is bonded into the metal's surface layer rather than applied as paint, so it's more durable than a painted finish.\u003c\/p\u003e\n\u003cp\u003eHow does it fit? The four finger holes measure approximately 25 × 29 mm each and are sized for a comfortable four-finger fit, with chamfered edges and a domed palm plate for a natural feel.\u003c\/p\u003e\n\u003cp\u003eIs it heavy? At around 132 g it feels substantial in hand but stays light enough for pocket or bag carry.\u003c\/p\u003e\n\u003ch3\u003eCare\u003c\/h3\u003e\n\u003cp\u003eMachined metal surfaces may show minor scratches, mould marks or polishing traces from production — this is normal, not a defect. Wipe clean with a dry cloth and store in a dry place to keep the anodized finish looking its best.\u003c\/p\u003e","brand":"KNUCKLEDUSTER","offers":[{"title":"Default Title","offer_id":67773554786435,"sku":null,"price":48.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0549\/6553\/4851\/files\/dc6ae7be31eabf2246c73f31ec1508ff.jpg?v=1791888946","url":"https:\/\/knuckleduster.co.uk\/de\/products\/shattered-crest-6061-t6-aluminum-knuckle-duster","provider":"KNUCKLEDUSTER","version":"1.0","type":"link"}
