Experience Long-Stroke Slicing with a Vintage Shomatsu Betsusaku Knife

Recorded Markings and Slicing Design

The existing inscription notes identify 商標登録 (Shōhyō Tōroku) as Registered Trademark, 正松 as Shōmatsu or Masamatsu, and 別作 (Betsusaku) as Specially Made or Special Production. The Betsusaku designation is preserved as part of the knife's identity without treating it as proof of a particular steel grade or production method.

The long, narrow slicing profile supports clean, uninterrupted strokes through roasts, fish fillets and cured meats, helping minimise repeated sawing and preserve presentation. The existing listing calls this knife a Sujihiki while recording a single bevel; both details are retained rather than changing its geometry from an assumption about the knife type.

Care & Maintenance

• Hand wash only - never put in the dishwasher
• Dry immediately after washing
• Apply a light coat of food-safe oil to help prevent rust on the carbon steel blade
• Sharpen on a whetstone, preserving the recorded single-bevel geometry
• Professional sharpening is recommended if unfamiliar with single-bevel knives
• Store on a magnetic rack or in a knife roll
