{"type":"firestarter.listing","listing":{"id":"lst_bTupyRti","product_name":"Takeshi Saji Ginsan #3 Deba 105mm with Deer Antler Handle","category":"Deba Knife","description":"Overview\nThe Takeshi Saji Ginsan #3 Deba 105mm with Deer Antler Handle is a compact Japanese ko-deba, also known as an ajikiri, designed for detailed small fish preparation. Handcrafted by master blacksmith Takeshi Saji of Echizen, Japan, this knife combines practical stainless performance with a rustic natural deer antler handle, giving each piece its own unique character.\nGinsan #3, also called Gingami No.3 or Silver #3, is a stainless Japanese steel known for taking a clean, sharp edge while being easier to maintain than reactive carbon steel. This makes it a smart choice for cooks who want traditional Japanese cutting performance without the same level of rust concern. At 105mm, this deba is ideal for cleaning, filleting, trimming, and butterflying small fish such as mackerel, trout, sardines, and other smaller catch.\nThe single bevel grind is made for controlled, precise fish work. Unlike a general-purpose gyuto or petty knife, a deba has a thicker, stronger blade profile suited for working around fish bones and heads. This compact size gives excellent control in the hand, making it especially useful for home cooks, anglers, sushi prep, and anyone who regularly works with smaller whole fish.\nThe natural deer antler handle is one of the defining details of this knife. Each handle varies in tone, texture, and shape, so no two knives are exactly alike. Saji-san is well known for bold, expressive handle choices, and this model captures that signature style while remaining practical for serious kitchen use.\nCommon Questions\nQ: What is a 105mm deba used for?\nA: A 105mm deba, often called a ko-deba or ajikiri, is mainly used for small fish. It is excellent for trimming, filleting, butterflying, and working close to bones where a larger deba would feel oversized.\nQ: Is this Takeshi Saji Ginsan Deba suitable for home cooks?\nA: Yes. This is a great choice for home cooks who prepare small whole fish and want a traditional Japanese knife with easier maintenance.
