Insert the point of a pick under the screen where you just stopped cutting. Don't insert the pick deeper than the edge of the bezel.

Carefully roll the pick to the right, pressing the long edge of the pick into the screen adhesive underneath the bezel, cutting the adhesive as you go. Don't slide the pick along the edge of the Surface.

Repeat this motion of inserting the point of the pick where you just cut, and rolling to the right all along the top edge of the Surface, until the pick is 2.5 inches (64 mm) from the right edge of the Surface.
