Vintage Seki-Yamato Kiridashi Utility Knife, Single-Bevel Carbon Steel, Japan

Single-bevel Japanese kiridashi for marking and detail work

This vintage Seki-Yamato kiridashi is a compact single-bevel utility knife for marking timber, carving details, sharpening pencils and making fine workshop cuts. The chisel-like edge gives direct control in wood and other light craft materials.

Use it as a small layout and craft knife, not as a pry bar or heavy outdoor knife. The carbon steel blade rewards clean cuts, careful sharpening and dry storage.

Best suited to

• Woodworking layout and marking
• Fine carving and trimming
• Pencil sharpening and paper cuts
• Leathercraft and light craft work
• Users who understand single-bevel sharpening

What to understand before buying

• This is a single-bevel tool, so it does not sharpen like a normal double-bevel pocket knife.
• This is vintage stock, so small cosmetic marks and variation should be expected.
• It is a sharp workshop tool, not a general-purpose heavy knife.

Who should not buy this

• Do not buy this if you want a locking folding knife.
• Do not use it for prying, twisting or rough outdoor work.
• Do not buy carbon steel if you want to store the blade wet or dirty.

Care expectations

Wipe the blade dry after use, sharpen the bevel carefully on a waterstone and protect the steel with a light coat of camellia oil before storage. Avoid grinding the flat side heavily, as that can spoil the single-bevel geometry.

Wipe the blade dry after use and store it clean. Use a fine waterstone or leather strop for touch-ups. For surface marks or minor rust, use a Kespika Rust & Grime Eraser and finish with camellia oil.
