To make these knives, Takayuki Shibata has teamed up with Ikeda-san, from Takefu Knife Village. Together they both do what they are good at and they are turning out awesomeness, Ikeda- san hammers the steel and Shibata-san does the finishing, sharpening, signs the blade and adds the handle.
They really are crazy sharp. R2 powdered stainless steel allows for an extremely long-lived edge and is tougher than many super hard powder steels. Having a light, thin blade this knife is capable of extreme sharpness. This steel competes with hard carbon steel for edge retention, but will never rusts. A total bonus.
