Complying with The International Cutting Test Standard for:
KITCHEN KNIVES | HUNTING, POCKET & FOLDING KNIVES | MACHINE BLADES | AGRICULTURAL BLADES | BOX CUTTERS & TOOL KNIVES | LARGE MEDICAL BLADES | WOOD CHISELS
For delicate blades such as razors and medical blades, see our Razor Edge Durability and Sharpness (REDS) Tester
The AET answers the questions “How sharp is the blade?” and “How long will the sharpness last?”
- Measures the edge sharpness and durability of a large range of blades and knives for quality control, research and development, and competitor product evaluation.
- Quickly and accurately measures important cutting performance data.
- Conforms fully to the International Cutting Test Standard BS EN ISO 8442-5 : 2004.
- Automatic sharpness tester is ideal for large sample sizes and extensive development projects and is completely programmable to allow operation to the standard or user’s own specification.
How it works:
The cutting-edge to be tested is mounted vertically and a pack of specially developed synthetic card is lowered on to it. By moving the blade back and forth repeatedly, the blade cuts into the paper; the depth of the cut being the measurement of sharpness. The test card is loaded with 5% silica, which has a mild wearing effect on the blade edge. The measurement of cut depth at each subsequent stroke can then be plotted to produce a wear curve for each blade tested.
