The Signature Line represents a form of craftsmanship that has become rare today. Each knife is crafted by Yoshito Yamakawa in Chiba using a process based on over 30 manual steps, limited to just two knives per day. Only 10 copies of this knife were forged.

Shirogami steel and the Honbazuke sharpening finish give the line exceptional sharpness and very direct feedback during cutting. At the same time, each knife embodies the depth of a workshop tradition that has been deliberately continued, even though it could have long since disappeared. This is precisely where their true strength lies.

Those who choose the Marco Spezial line are not simply selecting a knife, but a limited masterpiece with collector's value, uncompromising precision, and tangible craftsmanship. Like many traditional carbon steels, this line also requires a little more care in maintenance.
