The Zero Blade was designed to fit your Beardscape Beard and Hair Trimmer and provide the closest trim possible. The small-tooth stainless steel blade cuts extremely close. Less heat and friction means less sensitivity and irritation to your skin! The Zero Blade is a fixed blade at .2mm. Very few trimmers on the market can cut this close. We recommend using caution with this blade as it is very sharp and cuts super close. Instead of pressing onto your skin, try hovering over your skin using very gentle pressure - this should avoid any nicks, cuts or irritation.
