Hinokuni Shirogami #1 Petty Knife 150mm Kurouchi Cherry Wood Handle Made in Japan

Experience Shirogami #1 - Pure Carbon Steel from a Young Japanese Blacksmith

The Hinokuni Shirogami #1 Petty Knife 150mm is hand-forged in Kumamoto Prefecture by Hinokuni-san, a 31-year-old blacksmith who recently established his own forge after apprenticing under the renowned Nishida-san. Forged from Shirogami #1 - one of the purest carbon steels available - this petty knife takes an exceptionally fine edge and is a joy to sharpen. The kurouchi finish and cherry oval handle give it a distinctly traditional Japanese character.

Why This Knife Works

Shirogami #1 is a very pure carbon steel - almost identical to Aogami #1 except without chromium or tungsten. That purity means it forms an exceptionally fine grain structure at the edge, allowing it to reach a level of sharpness that stainless steels simply cannot match. It sharpens quickly and easily on Japanese water stones and responds beautifully to stropping. The trade-off is reactivity - Shirogami #1 will develop a patina with use and must be wiped dry after every use to prevent rust. For cooks who want the absolute finest edge on a petty knife and are willing to give it proper care, this is the choice. The kurouchi finish on the cladding adds a layer of protection and gives the knife its raw, hand-forged character.

Care and Maintenance

• Hand wash only - never dishwasher
• Wipe dry immediately after every use - reactive carbon steel will rust if left wet
• A natural patina will develop with use - this is normal and protective
• Sharpen on Japanese water stones - takes an exceptional edge with minimal effort
• Apply a light coat of camellia oil if storing for extended periods
• Store on a magnetic strip or in a saya sheath to protect the edge
