{"type":"firestarter.listing","listing":{"id":"lst_IiVDMbqk","product_name":"Hatsukokoro Kaijin Blue #2 Gyuto 210mm","category":"Gyuto Knife","description":"Overview\nThe Hatsukokoro Kaijin Stainless Clad Blue #2 Gyuto 210mm with a mono olivewood handle brings together workhorse performance, easy daily care, and a warm, organic aesthetic. Built around a Blue #2 carbon-steel core clad in soft stainless, this 210mm gyuto offers the bite and edge retention of traditional carbon steel with the lower-maintenance benefits of a stainless jacket—ideal if you want a serious upgrade from factory chef knives without babying a fully carbon blade.\nThe Kaijin blade runs slightly long at around 218mm of edge in the 210mm class, with a tall ~50mm heel and a spine that holds a comfortable ~2.2mm thickness from heel through the midsection. At roughly 165g, it lands in that sweet spot between laser and tank: enough spine and height for confident, board-contact chopping, but still thin and agile enough for precise slicing and detail work.\nFor this Tokushu Knife build, the blade is paired with a mono olivewood wa handle, giving you a lighter, slightly front-balanced feel compared to dense ebony, plus a striking grain pattern that looks at home in both professional and home kitchens. If you’ve been asking, “What’s a good stainless-clad Blue #2 gyuto for everyday cooking?”—this is exactly that lane.\nCommon Questions\nQ: Is the Hatsukokoro Kaijin Blue #2 Gyuto 210mm a good choice for home cooks?\nA: Yes. The 210mm length is comfortable even on smaller boards, while the tall heel and moderate weight give you confidence if you’re moving up from German-style knives. The stainless cladding keeps most of the blade face from rusting, so as long as you rinse, wipe dry, and don’t leave it soaking in the sink, it’s very manageable. At the same time, the Blue #2 core takes a very sharp edge and holds it well, so you spend less time sharpening and more time cooking.\nQ: How reactive is Blue #2, and how should I care for this knife?\nA: The exposed Blue #2 at the edge will patina over time—that’s totally normal and actually helps protect the steel.
