Talented Forge-Smith Master Yamamoto spent tremendous time for making this special edition “Core-Less Custom Damascus Petty Knife”.

What is Core-Less Damascus ?

As you know, the clad metal is produced by forging different layers of meal together, taking advantage of the strength of each piece as an integrated unit while ensuring any weaknesses are balanced out by each layer. With this clad technology, they have succeeded in forging two different Haganes of VG-10 and VG-2 steel layers together. It was considered to be impossible to forge two different high carbon steels together. It is layered of total 70 very thin VG-10 and VG-2 steels, that makes a Core-less multi-layer stainless Damascus steel. Thanks for this state-of-art technology that made it possible to compose of a perfect blend that produces a long-lasting and extremely sharp cutting edge, in addition to the resistance to bending, breaking and rusting. This blend layers also feature a beautiful vortex Damascus patterns.

Beautiful Core-Less Damascus blade matches well with the hand contoured Ironwood Handle. This is Forge-Smith Yamamoto’s Special Edition, available with only 1Pc.

A mainstay of professional Western kitchens, the Petty knife is a small general-purpose knife used for peeling, shaping, and slicing fruits and vegetables, chopping herbs, and making garnishes.
