    Very Good. Cut is smooth.

    I decided to give these a try after becoming beyond frustrated with my Hanzo shears. And I am so glad I made the switch. These are far superior than any of the Hanzos I owned at the lower price point.

    These are some serious blades. I’m now a lifetime fan!

    I had these on pre-order and they were well worth the wait! Cuts through thick hair like it’s nothing.

    Giving it a 4 star because the package was delayed in delivery. The Shear itself is amazing to use.

    The finger rings were too big for my tiny hands. The return process was easy.
