Takeshi Saji - Black Damascus Steak knife - SPG2 Damascus and Micarta - handmade knife
Takeshi Saji was born in 1948 in Takefu (Fukui prefecture), a city located roughly in the center of Japan and in the heart of an area for centuries devoted to the production of blades. His workshop is still there, built around the oven thanks to which, for several years now, Takeshi Saji has been forging steel (especially damascus) with which he makes various models of traditional Japanese knives. The choice of materials for the finishes (mainly natural), the essential lines - evocative of use - and the chromatic combinations of rare impact make his creations unique and unmistakable in the panorama of world cutlery and, at home, they have earned him the prestigious title of Maestro.

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.
