HANDLE WITH CARE- Very sharp blades on this edging tool! 

 This Edge Trimmer is adjustable. The Edge Cutting Range can be 0.1 inch to 0.4 inch. 
 You can use a wrench to unscrew the screw of the cover of the blade to switch the position of the blade and the interlayer, and the height of the blade can be up or down. There are four levels of elevation, each about 0.1inch high, and you can find the right height you need.
 This edge edging tool works well with many sizes! 10 oz cup - a 40 oz cup.

Step1: Put the cup flatly on the table.
Step2: Grip the cup and hold the cup body firmly against it with one hand.
Step3: Rotate along the edges of the top and bottom of the cup that need to be removed.
Keeping the side with the blade against your palm will make a difference in getting a straight and even edge.
