The Scissor attachment was easy to install. Have only done one pair of scissors (Henckels) Set the angle to 25 on the scale, When you are sharpening you need to watch out for the blade you are not sharpening (see photo) put tape on the blade. It does not like to hold small scissors, tried 3 pairs and none of them would hold tight. Doing my first pair I am liking it, but will have to practice on more to get good at it.
