If the smaller bevelers are leaving marks tap the tools lighter. You have a lot less surface area on the face of the tool to distribute the force from the maul, mallet, shoe..whatever you are using. I have some of Barry's and Clay Millers smaller bevelers and they can be a pain to bevel with due to how they react to even small changes in force from the maul.
Just keep practicing and asking questions and you'll get it down
