  3. ExtremaRatio - BF2CT Knife Stone Washed - Classic Tanto - knife

    Il BF2 è un chiudibile “full size” particolarmente indicato per l’impiego professionale da parte di operatori militari e di polizia sul campo. L’impugnatura è salda e confortevole; la clip, reversibile ed avvolgente, diventa un utile e comodo appoggio per il pollice in “reverse grip”. La guancetta è piena con i caratteristici piani ribassati per impegnare i “pin” d’apertura senza che sporgano dal profilo del coltello chiuso. La lama, disponibile in versione drop o tanto, ha l’arrotatura piatta e, come nel BF1, la punta particolarmente spessa e resistente. Il meccanismo di blocco della lama è il collaudato LINER-LOCK, coadiuvato da un meccanismo di sicura da azionare manualmente protetto da un carter.

  8. ExtremaRatio - BF2 V Stone Washed Knife - Sailing Knife

    This knife was designed and perfected in every detail for its primary use in the marine environment. The blade has a flat rounding that allows symmetrical cutting work with wider support. The tip, on the other hand, which is thick and durable thanks to the tanto version, allows greater penetration and a sharper, more precise cut. The stone washed finish process facilitates locating in the marine environment.

    The structure of the handle, made of anodized anticorodal aluminum, features a design with milling in concentric circles and lightening and anti-slip perforations so as to facilitate rinsing from saltiness. A small slot is cut into the middle of the cheek piece to allow for tightening or releasing smaller shackles. BF2 V is equipped with reversible clip; adjusting screw retainer for closing and opening the blade; 70-mm. knot shock ankle with fastening mechanism; and correctable. The presentation of the BF2 V took place on the Amerigo Vespucci School Ship.

    ABOUT THE STEEL

    More than just a damask, Coreless steel made by Japanese Takefu Steel comes with over 70 layers of VG10 and VG2 stainless steel welded, forged and coated between them so that you can form a lightweight, slim and durable blade with a spectacular damask outer pattern.

    The peculiarity of Coreless steel, unlike conventional rolled steel or Japanese San-Mai, is that it does not have a hard core steel that is used for the cutting edge but has both the VG10 and VG2 steels arranged to form the cutting edge so alternating and sequential to each other.

    This particular construction gives the blade - compared to the two steels that make it, individually taken - greater resistance to oxidation, higher surface hardness (up to 61.5HRC), 25% more than cutting capacity, 25% more than the wire hold capacity and 25% more resilience making the blade more robust and less subject to breakage.

    Thanks to this latest steel, Takefu Steel has been rewarded on Japanese territory for research and development and innovation in the cutting-edge landscape. Coreless steel has already been chosen by major brands such as Kai and Mcusta Zanmai who since 2017 proposed it on their top productions of professional kitchen knives.
