Safe and Accurate Trimming Experience: The KM-323 features an arched, rounded-edge blade head. A double-edged structure with R-shaped rounded corners was specifically designed for this purpose. Driven by a high-speed 9000 RPM motor, it effectively trims nose hairs; painful tugging or any form of irritation to the more sensitive nasal mucosa is vastly avoided. The blades themselves maintain a near-perfect smooth contact surface – excessive lengths only are cut, the protective role of nose hairs being preserved. Flexible conformity of the blade head to various nose shapes allows for efficient management of all stray hairs, inside and outside the nostrils. A low noise design (≤45dB) provides that all round quiet and comfortable trimming
