This solid classic has been used as a grip structure for tool handles for over 100 years. For good reason - a knurl provides a consistent and aggressive grip. Each 'knurl' is diamond shaped and creates sharp points. These sharp points provide grip, and the flat profile provides a stable base that allows for very positive feedback and better control compared to a mushroom texture. The user of this grip is more likely to be a racer and favours this texture for its more aggressive feel and precise control.
