Fragging is auctually pretty easy i just took a razor blade and about 1 a week cut the section that i wanted to frag with razor blade to keep from damagaing any tissue or what not, after that will notice a die off of about 1/8in where u have been cutting in the same spot for about 4 weeks, then gently tap that spot ounce or twice a day till it falls off, i did this and i did not loose one single head all though time consuming very rewarding.
