A Standard Test for Sharpness

How sharp is the edge? That is both the most important question a sharpener can ask, and possibly the hardest to answer. There are tests like cutting paper or shaving hair that are often used to demonstrate sharpness, and they are helpful to a point, but they lack the precision and standardization required to truly answer the question. However, a precise and standardized testing method is available. It is achieved using the PT50 Series Sharpness Testers from Edge-On-Up.

Measure and Quantify

The PT50 Series of Edge-On-Up Sharpness Testers give the ability to measure and quantify the level of sharpness of any given edge. They work by measuring the force in grams required to cut through a standardized, calibrated medium. The result is a number that can be used to compare the relative sharpness of edges.

Industrial Precision and Quality

There are three models of PT50 Sharpness Testers. The Edge-On-Up Industrial Edge Tester (PT50A) is the most precise. It is a crossover product with the industrial world, and of the three models of PT50 testers, it is the only one that is warranted for commercial/industrial use (3 years).

The Edge-On-Up Industrial Edge Tester Features:

• 25 measurements-per-second processor
• Very Fine 1 Gram Resolution
• Maximum Load Rating of 3000 Grams
• Heavy Steel Measurement Platform
• Industrial Strain Sensor
• Portable Lightweight Design
• 3 Button Operation
