Blade length checker: inches, millimetres and nearby knives.

Convert a blade length between inches and millimetres, then find catalog knives near that length. The result uses the maker’s blade-length label and does not determine cutting-edge length or permission to carry.

How do inches convert to millimetres?

One inch equals exactly 25.4 millimetres. Multiply inches by 25.4 to get millimetres, or divide millimetres by 25.4 to get inches. Catalog measurements keep the maker’s labels; the converted output is arithmetic rather than a new physical measurement.

Example: 3 inches = 76.2 millimetres.

Is blade length the same as cutting edge?

Blade length and cutting-edge length are different labeled measurements. A cutting-edge figure must not be filled from a blade-length figure when the maker does not publish both. Our specification guide also separates open overall length from closed handle length. This tool uses only catalog blade-length fields and retains their source labels.

Read knife specifications. Local law varies; check your own jurisdiction’s official source.

Which catalog knives are near this length?

The interactive list shows catalog blades within the window you enter around the converted length. The window is your search preference, with a changeable example default rather than a maker specification. Models with no published blade length are omitted from numeric matching. Without JavaScript, the complete source-linked blade-length table remains available.

    Questions and answers

    These answers explain the scope of this reference. Check the linked maker instructions for the exact knife or abrasive.

    What does blade length mean?

    Keep the maker’s measurement label attached. It differs from overall length and may differ from the cutting-edge length; ask the maker when the measurement basis is unclear.

    Does an 8-inch knife include a handle?

    Check whether the maker labels the figure as blade, open overall or closed length. This tool only matches fields labeled as blade length in our catalog.

    What is the typical blade length for an EDC knife?

    This catalog is a small documented selection and cannot establish a population average. Use the length window to find examples, then compare the carry format and maker instructions.
