As a boss would you fire someone for not eating a meal that you offered them?
first, you need to determine what kind of segment you are dealing with. some segments can be tougher to divide than others. i highly recommend for the tough jobs, a diamond blade. Diamond blades are some of the toughest blades available on the market. They tend to be a bit pricey, but if you want the job done right, you have to use quality materials. For small jobs, a pair of scissors should do nicely. Once you have the appropriate tools, simply cut them into sections, and oila, three congruent parts. Good Luck! oh and make sure you wear safety goggles. Safety is the number one precaution!
