Available in six sizes from 5\/0 to 12\/0 in 5-hook packs. Suited to big game and offshore bait fishing for tuna, kingfish, snapper, mulloway and shark in Australian waters.\u003c\/p\u003e\u003ch2\u003eHow a Circle Hook Works — Self-Setting Corner Hookset\u003c\/h2\u003e\u003cp\u003eA circle hook has a fundamentally different geometry to a J-hook. The point of a circle hook curves back toward the shank in a circular arc, so that the point is angled inward rather than projecting away from the shank. When a fish takes the bait and moves away, the circular geometry causes the hook to rotate as tension is applied:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe rotation mechanism\u003c\/strong\u003e: as the line tightens, the circular hook body rotates within the fish’s mouth; the inward-curving point sweeps across soft tissue without penetrating until it reaches the corner of the mouth, where the angle of the jaw creates a contact point that stops the rotation and drives the point in; the hook self-sets at the corner of the mouth without requiring a sharp strike from the angler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner of mouth hookset\u003c\/strong\u003e: the corner of the mouth is the strongest hookhold position — the jaw tissue is thickest and toughest there compared to the soft palate or throat; a corner hookset is also the easiest to remove cleanly for catch-and-release, as the hook can be backed out the same way it went in without requiring the barb to tear through additional tissue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced deep hooking\u003c\/strong\u003e: because the point only penetrates when it reaches the corner geometry, the hook does not penetrate in the throat, gut or gill area during the rotation; this is the primary mechanism by which circle hooks reduce deep hooking compared to J-hooks, which penetrate immediately on any contact between the point and soft tissue\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eOffset Circle Design\u003c\/h2\u003e\u003cp\u003eThis hook is an \u003cem\u003eoffset\u003c\/em\u003e circle hook — the point is angled slightly to the side of the hook’s plane rather than being perfectly in-line with the shank. A straight (non-offset) circle hook is the purest self-setting design but can have lower hook-up ratios on species that mouth baits tentatively before committing. The offset increases hook-up ratios by initiating penetration slightly earlier in the rotation cycle, at the cost of a marginally increased deep-hooking risk compared to an in-line circle. For bait fishing for tuna, kingfish and snapper where the fish strike decisively and at speed, the offset circle is the preferred configuration.\u003c\/p\u003e\u003ch2\u003ePre-Attached Copper Barrel Swivel\u003c\/h2\u003e\u003cp\u003eEach hook comes with a copper barrel swivel attached between the hook eye and the leader connection point. The swivel serves two functions:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBait rotation\u003c\/strong\u003e: live and dead bait fish (yakkas, slimy mackerel, pilchards, strips) rotate as they move through the water; without a swivel, each rotation of the bait transfers torque directly to the leader, accumulating twist that weakens the leader and causes it to kink and tangle around the hook; the barrel swivel absorbs each rotation of the bait independently, preventing twist transfer to the leader\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTangle reduction\u003c\/strong\u003e: when a bait on a long trace is cast and retrieved or trolled, the trace can wrap around the leader on the swing; the swivel at the hook end creates a pivot point that reduces the wrap frequency and allows any wraps to unwind rather than tighten\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe swivel is copper rather than stainless — copper barrel swivels have a smooth internal bearing surface that rotates freely under low torque loads, which is important for detecting the gentle rotation of a live bait rather than only spinning when torque load reaches the swivel’s threshold.\u003c\/p\u003e\u003ch2\u003eHigh-Carbon Steel Construction\u003c\/h2\u003e\u003cp\u003eThe hook wire is high-carbon steel. For large pelagic species — tuna, kingfish, large snapper — the initial run after the hookset generates significant load on the hook wire, the bend and the point. High-carbon steel provides higher tensile strength per unit of wire diameter than standard carbon steel, allowing the hook to maintain its shape and point position under the load of a fish running at speed without the bend opening or the point deforming. The hooks are corrosion-treated for use in both freshwater and saltwater.\u003c\/p\u003e\u003ch2\u003eSize Selection\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e5\/0\u003c\/strong\u003e — smaller bait presentations; mid-size snapper and kingfish on half pilchard and whitebait baits; suitable for snapper in the 2–5kg range from reef and rock platforms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e6\/0\u003c\/strong\u003e — whole pilchard and small slimy mackerel; general snapper and large bream baits; offshore reef fishing for snapper and large flathead\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7\/0\u003c\/strong\u003e — whole slimy mackerel and medium live baits; kingfish in the 5–15kg range; school and large snapper from boat and rock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e8\/0\u003c\/strong\u003e — large live baits (yakka, small bonito); kingfish in the 10–25kg range; mulloway on large whole baits in estuary and offshore environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e10\/0\u003c\/strong\u003e — large whole baits for big game; southern bluefin and yellowfin tuna on whole pilchards and medium live baits; large mulloway\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e12\/0\u003c\/strong\u003e — largest size; very large whole baits for trophy-class tuna and shark; suits heavy game outfits with 80–130lb leader\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrand: 9KM DWLIFE\u003c\/li\u003e\n\u003cli\u003eType: Offset circle hook with swivel\u003c\/li\u003e\n\u003cli\u003eMaterial: High-carbon steel, corrosion resistant\u003c\/li\u003e\n\u003cli\u003eSwivel: Copper barrel swivel\u003c\/li\u003e\n\u003cli\u003eSizes: 5\/0, 6\/0, 7\/0, 8\/0, 10\/0, 12\/0\u003c\/li\u003e\n\u003cli\u003ePack: 5 hooks per pack\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"9KM DWLIFE","offers":[{"title":"Size5-0","offer_id":49391544893614,"sku":"14:29#Size5-0","price":22.95,"currency_code":"AUD","in_stock":true},{"title":"Size8-0","offer_id":49391544926382,"sku":"14:1063#Size8-0","price":36.95,"currency_code":"AUD","in_stock":true},{"title":"Size10-0","offer_id":49391544959150,"sku":"14:193#Size10-0","price":41.95,"currency_code":"AUD","in_stock":true},{"title":"Size12-0","offer_id":49391544991918,"sku":"14:200006152#Size12-0","price":48.95,"currency_code":"AUD","in_stock":true},{"title":"Size7-0","offer_id":49391545024686,"sku":"14:10#Size7-0","price":26.95,"currency_code":"AUD","in_stock":true},{"title":"Size6-0","offer_id":49391545057454,"sku":"14:366#Size6-0","price":24.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5592\/2350\/files\/S622935832e02411a9d5d1f82910383d7V.webp?v=1790274128","url":"https:\/\/castngo.com.au\/de\/products\/9km-dwlife-offset-circle-hook-swivel-5-pack-high-carbon-steel-5-0-to-12-0-tuna-kingfish-snapper","provider":"Cast N Go","version":"1.0","type":"link"}
