The SENSEI DRY EVOLUTION shear takes dry cutting to a whole new level of PRECISION. It starts with a completely new edge design that allows you a much greater ability to cut dry hair without as much movement on the blade. Hydrogen bonds are intact in dry hair making it 30% harder to cut which is why we have invented the PRECISION DRYCUT blade design.This added precision, will speed up your work and give you a new level of control. Of course it’s smooth and precise for wet hair too. Made from Japanese Cobalt/Molybdenum alloy steel with SENSEI CRYO Tempering the precision of this blade will last and last. The tension system features ball bearings to stabilize the blades for longer life. The handle is beautifully sculpted to feel great in your hand.
