{"product_id":"coltello-glock-fm-78-nero","title":"Glock FM 78 Knife — Black","description":"\u003cp\u003eThe Glock FM 78 is a fixed-blade utility knife designed for field use by military personnel, law enforcement and outdoor professionals. With an overall length of \u003cstrong\u003e290 mm\u003c\/strong\u003e and a blade length of \u003cstrong\u003e165 mm\u003c\/strong\u003e, it sits in the mid-range of utility knives: manoeuvrable enough for precision work, long enough to handle heavier tasks.\u003c\/p\u003e\u003cp\u003eThe blade is made from hardened steel at \u003cstrong\u003e55 HRC\u003c\/strong\u003e with a matte black finish that reduces reflections in operational conditions. The top edge is serrated, making it effective on fibrous materials such as ropes, straps and technical clothing without requiring excessive pressure. A 55 HRC rating is a deliberate compromise: it offers good edge retention and impact resistance, and is easier to resharpen in the field than harder grades, though it requires more frequent maintenance in humid or saltwater environments.\u003c\/p\u003e\u003cp\u003eThe smooth polymer handle is lightweight and does not absorb moisture, but offers less grip when wet compared to aggressively textured handles: the double guard partially compensates by preventing the hand from slipping towards the blade. The lanyard hole at the base allows attachment to a retention ring or safety system. The polymer sheath accepts belts up to \u003cstrong\u003e60 mm\u003c\/strong\u003e wide and features an integrated thumb-break clip for single-handed drawing without releasing any catch — an advantage when the other hand is occupied, at the cost of less rigid passive retention compared to a snap-lock system. The knife alone weighs \u003cstrong\u003e206 g\u003c\/strong\u003e.\u003c\/p\u003e\u003ch2\u003eKey features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe \u003cstrong\u003e55 HRC\u003c\/strong\u003e steel blade strikes a good balance between edge retention and field sharpenability, without specialist tools.\u003c\/li\u003e\n\u003cli\u003eThe spine serrations cut through ropes and fibrous materials where a plain edge would require more strokes.\u003c\/li\u003e\n\u003cli\u003eThe double guard keeps the hand clear of the blade even with grip weakened by gloves or wet conditions.\u003c\/li\u003e\n\u003cli\u003eThe polymer sheath with thumb-break clip allows single-handed drawing, compatible with belts up to \u003cstrong\u003e60 mm\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003eThe matte black blade finish eliminates reflections without adding weight or compromising maintainability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIn the box\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGlock FM 78 knife\u003c\/li\u003e\n\u003cli\u003ePolymer sheath with retention clip\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Glock","offers":[{"title":"Default Title","offer_id":63798959505738,"sku":"GLOCK16","price":50.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0026\/3920\/0291\/files\/46740.jpg?v=1791148426","url":"https:\/\/www.vipertactical.es\/en\/products\/glock-fm-78-knife-black","provider":"Viper Tactical ","version":"1.0","type":"link"}
