The Wahl Beretto Lithium Ion Clipper is the perfect meeting of modern, cutting-edge ergonomic design and technological advancements in functionality and power. The aforementioned Lithium Ion battery is perfect for busy environments with it never losing charge while switched off unlike most other batteries available. A notable aspect of the clipper is its blade; easily detachable while still able to vary its cutting length from 0.8-2.5mm for incredibly consistent results. The blade is another example of the company?s innovation, being completely rust resistant so its chrome plated, grinding technology is never diminished over time.
