RUI Sharpness Tester/ Sharpness Scale FREE SHIPPING
5 gram Accuracy
Industry-Compliant Design
Engineered in accordance with the medical standard YY0174 “Surgical Blades”, this tester meets professional-grade sharpness evaluation criteria.
Innovative Testing Principle
Using a precision industrial-grade fixture and standard cutting media (3-0 surgical suture or 0.8 mm carbon line), the device replicates the performance of high-end lab equipment. By manually applying a downward cutting motion at ≤10 mm/s, it accurately captures peak cutting force—delivering reliable sharpness readings without the need for automated machinery.
Compact. Accurate. Cost-Effective.
This groundbreaking tester reimagines the traditional lab blade tester, replacing bulky automated systems with a smart manual press design. The result: a compact, portable device that dramatically reduces production and operating costs—while maintaining lab-level accuracy. Perfect for professionals who demand efficiency, mobility, and precision at a fraction of the cost.
