need a saw blade or special cutter for a custom pattern...go to Keen Edge or call and ask for Chester. Plan to talk awhile if he has the time and you will learn more than you could imagine. they are smaller store than when in downtown Atlanta but sometimes we all can learn that great things can come in small package. if they don't have it or can't get it, likely you don't need it anyway but if you do they will be able to tell you where to go for the best quality and pricing. Plan to be greeted by a small friendly family group of folks with the smiling wagging tails of the friendly dogs that work almost every day.
