art At first I was concerned that these mullets would do the job I needed them for. (Cut the designs into very small pieces of natural stone. I was concerned they would be either too light or too heavy.) It turns out each hammer head is just the right weight to not require a lot of force behind it, while he remains motionless. be effective in chiseling tiny pieces. I really enjoy using them as they are well made and easy to use. Would definitely buy again.
