Cut HM Location
HM Cut allows you to cut down small trees that would otherwise block your path. The trees are small and have two bushes sprouting from its trunk (see below).
You will receive HM Cut from Cynthia in Eterna City, the first time you walk near the Eterna City Galactic Building.
How to Use Cut
Simply press the A Button towards the small tree and you’ll be prompted to use Cut.
Alternatively, while facing a small tree, open up and zoom into your Pokétch by using the R button.
While zoomed in, move the cursor with the Left Stick and press the A button while on top of the big red button on the right side to cycle to the Hidden Moves app. (You can also cycle by clicking the Right Stick inwards.)
When you’re on the Hidden Moves app (while zoomed in), hover over Cut with the cursor and then press the A button.
