It was actually very easy to do. If someone cares about weight and balance to be directed more towards the handle I can recommend this procedure. I bought tiny saw for 2$, sand paper for 0.5$ and just went for it. It looks like factory new edge. Obviously the sides should be shaved less, from 0.1mm on the side to 5mm on top. That way you don't lose vertical surface. From what I remember it saved approximately 8g, mileage may vary depending on the blade and rubber. I think it could be a good option for kids aswell. Anyway good luck hunting.
