blades honed to a fine mirror polish. The Green Series is designed with a ball bearing tension system. This feature reduces friction and allows you to power through a large section or thick hair, while reducing any fatigue on the fingers and thumb. Performance is excellent with a very solid feel in your hand. The Green Series includes the texturizers, where the teeth are so shaped by up-to-date erosion technique that each tooth meets the cutting edge at the same angle. The gaps between the teeth are tapered towards the inside of the teeth blade, which prevents a tangle of hair when pulling out. The convex blades are mirror polished.
