Thank you for viewing. I am selling this because I have had fewer opportunities to use it, although it was for home use. It is a Hakushika Kanemono brand black-forged double-edged Ajikiri knife from Miki City, Hyogo Prefecture, with a blade length of approximately 105mm, made of Shirogami No. 2 steel. Quoted from the website. The sharpness was personally the best. I am an amateur, but I have stored it wrapped in rust-preventative paper after sharpening. I will include one new sheet of rust-preventative paper, approximately 200mm x 200mm, as a service. Please consider this item with the understanding that it is a used product.
