A product name is not always the measurement to use when choosing a knife. Ichimonji's October 17 notice covers a kiritsuke-style sujihiki whose sales began on October 6. The name includes 270 mm, while the official specification gives a 260 mm actual blade length for model 1bs3ks.
Dimensions and buying conditions
The product table also lists 415 mm overall and approximately 145 g. Ichimonji cautions that its handmade knives vary in weight and length. The displayed price is ¥68,000 including tax; current stock has not been verified.
The domestic store says it accepts orders only from within Japan and directs overseas customers to a separate global store. That direction does not confirm that this exact model is offered internationally or can be delivered to a particular country.
Stainless steel still comes with care instructions
Ichimonji describes a stainless-steel, double-bevel blade and an octagonal magnolia-wood handle. Its care instructions call for washing away residue and drying the knife completely after use, and exclude cutting frozen food. Those instructions are useful context alongside the stainless-steel specification; they are the maker's guidance, not a result of our testing. We have not tested the knife or measured its edge retention.
