This knife is a custom-made kiritsuke-style yanagiba, originally based on a 1-shaku-ichi (approx. 33cm) yanagiba. While the product title states "1 shaku (30cm)", the actual size is 30.5cm. It has a special-made stamp. Knives with "betsudan" (special order) or "betsusaku" (custom made) stamps often use higher-grade steel. The material is likely Shirogami No. 2, or at the very least, Shirogami No. 3 carbon steel, known for being easy to sharpen and providing a quick edge. When sharpened, it's characterized by a balance of toughness and sharpness. Besides sashimi, it's a versatile knife suitable for light chopping and skinning, making it a near-universal tool. As you can see from the product images, it has a mirror-like shine due to buffing. It is more resistant to rust compared to standard carbon steel knives. It is a beautiful item, but not completely new and unused, so there may be minor scratches or storage marks. It has been sharpened, so it's ready to use upon arrival. The handle has been sanded and treated with camellia oil before listing, ensuring hygiene. Shipping: We will carefully pack and ship the knife after confirming it is rust-free.

The market price is around 40,000 to 60,000 yen (depending on the brand). *Please use this as a guideline only. Thank you for viewing.
