In particular, the initial tightening of the FG knot required removing the line and using a large stick to tighten it using the angler's back muscles, forcing anglers to rely on their physical strength for knot tying. Therefore, we developed a BM (Big Mouth) model with the concept of evolving to be suitable for use with ultra-thick lines from PE #10 and up, and making tightening easier.\u003c\/span\u003e\u003cbr\u003e\u003cspan dir=\"auto\"\u003eIn addition to its function as an FG knotter, it is a highly versatile knotter that is also ideal as a tightening tool for MID knots and tube knots.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"p-product__title c-gradient-text\"\u003e\n\u003cspan dir=\"auto\"\u003eTightening mechanism based on the principle of leverage (PAT.P)\u003c\/span\u003e\u003cspan dir=\"auto\"\u003e\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cp\u003e\u003cspan dir=\"auto\"\u003e\u003cimg src=\"https:\/\/studio-oceanmark.com\/wp-content\/uploads\/2026\/08\/OK230BM-PHOTO4-00.jpg\" alt=\"\" decoding=\"async\" class=\"ls-is-cached lazyloaded\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan dir=\"auto\"\u003eBy employing a lever-based force-multiplying mechanism, the force required to open the knotter is doubled, enabling powerful tightening.\u003cbr\u003eSince tightening can be done within the entire FG knot-making process, knot-making time is significantly reduced.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"p-product__title c-gradient-text\"\u003e\n\u003cspan dir=\"auto\"\u003eCompatible with extra-thick lines\u003c\/span\u003e\u003cspan dir=\"auto\"\u003e\u003c\/span\u003e\n\u003c\/h2\u003e\n\u003cp\u003e\u003cspan dir=\"auto\"\u003e\u003cimg src=\"https:\/\/studio-oceanmark.com\/wp-content\/uploads\/2026\/08\/OK230BM-PHOTO5-00.jpg\" alt=\"\" decoding=\"async\" class=\"ls-is-cached lazyloaded\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan dir=\"auto\"\u003e\u003cspan\u003eThe large-diameter rubber ring, which can temporarily secure a PE15\/300lb leader, has twice the diameter and 1.5 times the aluminum plate thickness compared to the OK105H.
