METHODOLOGY
Blade Knives Sharpness Edged Tester Blade Sharp Edged Tester is mounted in a position with the edge vertical. The blade is moved back and forth whilst a pack of special testing paper is lowered onto the blade. The blade cuts through the paper and the sharpness is then measured.
SPECIFICATIONS
1. Applicable Standards: EN ISO 8442-5
TWO MEASUREMENTS ARE PRODUCED
1. Initial Cutting Performance (ICP) This measurement is based on the first 3 strokes, which represents the cutting ability or the sharpness of the blade.
2. Total Card Cut (TCC) This is measured by conducting over 60 strokes, which represents the life of the blade. These two measurements are produced and recorded by a microcomputer for each of the knives tested.
