Sukehisa Hamono Co., Ltd., located in Tokyo's Adachi district, built its reputation over decades by supplying commercial kitchens, traditional Tokyo butchers, and Western cuisine (Yo-shoku) restaurants in the capital's dining districts. The brand's philosophy was simple: utility, balance, and pure edge quality\u2014no frills. The workshop was particularly known for its precise heat treatment of carbon steel\u2014the yaki-ire and yaki-modoshi processes\u2014which define the blade's character more than anything else. The workshop has since ceased production, and NOS Sukehisas are becoming increasingly rare on the used market.<\/p>\n

Technical characteristics<\/strong><\/p>\n Minamoto Sukehisa (\u6e90\u52a9\u4e45) is a true heir to the Tokyo School of blacksmithing\u2014a tradition that traces its roots directly to Edo-period swordsmiths who, following the 1876 ban on swords (Hait\u014drei), turned their craft to professional kitchen knives. Unlike large-scale mass-production centers like Sakai or Seki, Tokyo Hamono is a smaller, lesser-known scene\u2014but precisely because of this, it's more authentic.<\/p>","protected":false},"featured_media":4919,"template":"","meta":{"_uag_custom_page_level_css":"","iawp_total_views":1},"product_brand":[],"product_cat":[33,23],"product_tag":[],"class_list":["post-4918","product","type-product","status-publish","has-post-thumbnail","product_cat-minamoto-sukehisa","product_cat-noze-uniwersalne","first","instock","shipping-taxable","purchasable","product-type-simple"],"uagb_featured_image_src":{"full":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022.jpg",1200,896,false],"thumbnail":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-150x150.jpg",150,150,true],"medium":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-300x224.jpg",300,224,true],"medium_large":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-768x573.jpg",768,573,true],"large":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-1024x765.jpg",980,732,true],"1536x1536":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022.jpg",1200,896,false],"2048x2048":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022.jpg",1200,896,false],"trp-custom-language-flag":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-16x12.jpg",16,12,true],"woocommerce_thumbnail":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-324x243.jpg",324,243,true],"woocommerce_single":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-416x311.jpg",416,311,true],"woocommerce_gallery_thumbnail":["https:\/\/shirogami.pl\/wp-content\/uploads\/2026\/10\/Isolate_items_on_white_background_20261020211022-100x100.jpg",100,100,true]},"uagb_author_info":{"display_name":"admin","author_link":"https:\/\/shirogami.pl\/en\/author\/"},"uagb_comment_info":0,"uagb_excerpt":"Minamoto Sukehisa (\u6e90\u52a9\u4e45) to autentyczny spadkobierca tokijskiej szko\u0142y kowalstwa \u2014 tradycji wywodz\u0105cej si\u0119 bezpo\u015brednio od mistrz\u00f3w mieczy z okresu Edo, kt\u00f3rzy po zakazie noszenia mieczy w 1876 roku (Hait\u014drei) skierowali sw\u00f3j kunszt w stron\u0119 profesjonalnych no\u017cy kuchennych.
