SUPER GOU: 161 Layers Blade The blade core is made of ultra-hard SG2 Micro-Carbide powder stainless steel which is enveloped by 80 layers on each side with soft and hard stainless steel. This powdered steel contains a lot of carbon and has an unprecedented hardness of approximately 63 Rockwell. Powdered steel is used because it ensures a high degree of purity and exceptionally sharp cutting edge. The surface impresses with a fascinating Damascus design pattern - a symbol of the highest quality knife and its signature, Super GOU 161 layers. Handle: The beautiful handle is made out of FDA-approved red-black Canvas Micarta, which is an odorless and enormously durable material made of resin and linen. The Canvas material is dyed red and black and brilliantly finished. This material lasts decades. The handle is attached tightly using three stainless steel rivets. The handle is supported by the high quality 18-10 stainless steel inside, which gives the knife outstanding stability and balance. The trade mark 'GOU' is engraved on the grip end in a noble style. The shape of the handle allows tireless working in all cutting techniques.
