Handles of Mediterranean olive wood, cut so no two share the same grain. Each knife in the series pairs that warmth with the full ZAKU geometry, from a 90mm paring knife to a 270mm sujihiki, so the set covers everything a kitchen asks of it. The wood deepens in color with use and hand oiling, slowly taking on the character of the cook who carries it. Every shape and size follows the same edge and balance standards as the rest of the ZAKU line.
