From the Chubo website: Karaku knives are forged in Tosa region of Shikoku by blacksmith Michikuni Tokaji, from Aogami #1, a highly regarded blue steel known for its ability to get incredibly sharp and hold an edge. The dark, traditional kuroichi finish offers protection from discoloration. Handles are made from magnolia (ho) wood and turned in a D shape. Overall, a great value and ideal starter knife for cooks interested in traditional carbon steel blades and Japanese style handles. Please note: This knife is made from carbon steel, which gets incredibly sharp and is easy to sharpen but requires additional maintenance. This knife should be kept clean and dry at all times and oiled when not in use for an extended amount of time. Carbon knives can be reactive with high acid foods. The word gyutou in Japanese means ‘beef knife’. *From me, the seller* Because this knife is carbon steel, and has never been used, that knife material has mild rust spots this is common with carbon steel.. Chubo sent a bottle of oil and a rust remover pad. I've kept it oiled and protected the best I could. NEVER USED. STILL IN THE BOX WITH ALL THE PAPERWORK. The Chubo website lists the current price as $129.00 *****The first 2 pictures are from the Chubo website*****
