How do you use a Sharp edge tester?

Published in Sharpness Testing 2 mins read

Using a sharp edge tester involves a specific procedure to determine the sharpness of an edge. Based on the reference provided, here's a breakdown of how to use an Edge-On-Up Edge Sharpness Tester:

Steps for Using a Sharp Edge Tester

Here's how to use the tester, based on the video description:

  1. Zero Out the Tester: Before each test, it's crucial to zero out the sharp edge tester. This ensures an accurate reading. There should be a button or mechanism to accomplish this.

  2. Position the Test Media: The tester utilizes test media that breaks under a certain pressure, indicating sharpness.

  3. Place in the Pivot Point: Position the edge to be tested against the pivot point of the tester.

  4. Slowly Apply Pressure: Gently and gradually bring the tester down onto the edge being tested.

  5. Observe Until Media Breaks: Continue applying pressure until the test media breaks or is cut through by the edge.

  6. Read the Measurement: Once the media breaks, the tester will display a reading, typically in grams of pressure. For instance, the reference mentions a reading of 213 grams of pressure. This value indicates the force required to break the media, thus quantifying the sharpness of the edge.

Example

Imagine testing the blade of a knife. You would:

  • Zero out the tester.
  • Position the knife blade at the pivot point.
  • Slowly lower the tester.
  • Observe the point at which the test media breaks.
  • Note the reading on the tester (e.g., 213 grams).
