How We Measure Knives

Knife measurements can be confusing. “Blade length” and “cutting edge” may sound like the same thing, but they describe different parts of the knife. Here’s how we measure them at Monkey Edge.

Cutting edge is measured in a straight line from the tip to the end of the sharpened edge. On a curved blade, we don’t trace the curve.

Blade length is measured in a straight line from the tip to the front of the handle. This includes unsharpened portions of the blade, such as a ricasso.

Overall length is measured from the tip of the blade to the end of the handle.

Some blade shapes and blade-to-frame designs make these reference points less straightforward. For example, a sharpened edge may extend back under the frame. Measuring to the frontmost point of the frame can then produce a blade length that’s shorter than the cutting edge measurement. When that happens, we use the area where the sharpening choil meets the frame as a practical reference.

The infographic above shows the points we use. Our measurements are taken by us using this method, and they may differ from a manufacturer’s listed specifications. If you’re looking for a manufacturer’s measurement, check the maker’s own product information. Measurement conventions can also vary, so check applicable local laws if you have a legal question about a specific knife.
