The hewing stone technique helps you customize the size and shape of your stone. Although cutting stone is hard work, but if it is done properly, the process is simple and you would be able to do it just by using a few tools such as a chisel and hammer. There are three types of chisel commonly used for hewing stone that are the flat-blade, point and tooth. The flat-blade chisel is a wide flat end that looks like a flathead screwdriver while the point tip chisel is designed with a four-sided point that shaped like a four-sided pyramid. As for the tooth chisel, it features a square surface that has four or more small points arranged on it where each chisel is capable of creating different effects. For beginners who just learn to hew stone, it is recommended that you use a flat-blade.
