Back when I got into ASLSK, I learned about this thing called clipping corners on game pieces. I was converted pretty easily. It looks so much nicer, the pieces don't reach out and grab each other, and stack better.
Though it is a pain in the tush. Many people use nail clippers. Some use parts of an old CD case and clippers, some use a tool called the C4 Corner Cutter (my preferred choice) and some have found some cool tool from a company...that the name is slipping me... but here's a post to a very detailed discussion on the merits of the different options on Board Game Geek.
