Masamoto knives have been historically used as the Highest-Integrity Professional Chef Knife Brand in Japan (refer to the bottom of this page).
Masamoto "KH" Damascus Hon-Kasumi Gyokusei-ko series are crafted out of a multi-layer Damascus-patterned beautiful blades with a core of Blue Paper (Aoko or Aogami) No.2 Yasugi Steel, known as prime high carbon steel, specifically developed for tools and knives.
This one has highest wear resistance and toughness. Very good steel, and very popular choice for high end Japanese kitchen knives, but requires special care to avoid rusting and chipping.
Speaking to the handle, the beautiful two Ebony Ring and the Buffalo Tsuba equipped to the Magnolia Wood handle represent high-quality and excellent durability, that means made for professional originally.
The handle shape of Japanese-Style Octagonal figure fits better comfortably to your hand.
