PBHE’s pattern grinding ensures specific curves for individual competitors and is consistent for every sharpening. As a result, there is no transition time after each sharpening. This is impossible to achieve with freehand grinding because of human inconsistency and control. Most PBHE competitors get their blades sharpened days before major competitions and have interchangeable pairs of skates due to PBHE’s grinding consistency. In addition PBHE’s grinding process extends blade life by two to three times because each sharpening takes off the minimum material.
