A piercing saw (small jewellers saw) is too difficult to control to cut the greneng. The biggest difficulty with the greneng is making sure the shape is exactly the same on both sides of the gonjo. With a file you can cut as near as you can the same, then just deepen the more shallow side a little to make it the same as the other one. You cannot do this with a piercing saw. You do not use a hacksaw to cut the greneng, you draw your shape with a scriber---draw it less than the size you want it to finish--- then you cut it from start to finish with jewellers files.There will be a rough edge on the outside of the cut when you finish, you must be very careful not to alter the shape of the greneng when you smooth away this roughness. You can polish the inside of the cuts with wet and dry paper wrapped around a sate stick. The main thing is to work very carefully and think before you cut---make sure you have a very clear picture in your mind of what you want to produce. This is the hardest thing in the whole process:- getting the clear mental picture of the form that will carry the feeling you are trying to generate.
