Nigara Hamono is located in Hirosaki which is a city at the very northen tip of the main island of Honshu. Their family has a 350 year old history of making knives and swords and more recently has expanded into structural steel beams for use in construction. Tsuyoshi Yoshizawa stands as the 8th generation smith in the lineage of blacksmiths at Nigara Hamono and creates knives with his younger brother and two other craftsman.
*These knives are extremely thin behind the edge, this gives them an unbelievable cutting feel but makes them more delicate than even other Japanese knives. Twisting and torquing the knife on the board or in an ingredient will certainly cause chipping. Make sure to use only up and down, forward and back motions with the knife.
This Knife is made from 3 layers of material; A layer of iron on each side protecting a layer of carbon steel at the core, in a process referred to as Sanmai or forge welding. Iron and carbon steel are both susceptible to rust and must be kept dry and clean at all time’s to avoid oxidation and discolouration.
Simply wipe the knife with a damp cloth immediately after use.
Wash with regular dish soap and warm water using a none abrasive sponge or cloth.
Never put your knife in the dishwasher! The extreme heat will ruin the wooden handle.
Highly acidic ingredients (Onions, Tomatoes, Citrus) Will cause rust and oxidation to happen faster, thus the user must ensure the knife is wiped clean immediately after working with such an ingredient.
Should any rust form it can be removed using a rust eraser or a mixture of Baking soda and water to simply scrub it clean.
Avoid Bones, Frozen foods, nuts and hard candies or anything other than fruits, vegetables and proteins.
