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.

With Shun Nagare, Kai created another innovative Japanese forging masterpiece. This series of fine-knotted knives, thanks to the special features of the materials and the technically complex production process they are made, is located in the extralusso class. Mirrored blades have a damask damask pattern. The dark gray-black handle further enhances the beauty of the knife. The blades of this series are made with two different qualities of steel, bonded to form a 72-layer Damascus steel. The complex machining of the two steel grades produces a blade with exceptionally long lasting cutting performance.

Il JB2 è realizzato in acciaio Sandvik 13C26 con copertura DLC al tungsteno.

La parte finale ha un foro con un angolo tagliente di 270° ed uno spessore di 2mm. specificatamente studiato per tagliare cinture di sicurezza e paracord garantendo la massima sicurezza.

Al termine dell'impugnatura trovano invece posto un pratico skull-crasher ed una chiave esagonale adatta ad aprire bombole di ossigeno.

Il tutto è corredato da un pratico fodero in Nylon adatto anche per aviolanci.
