I went to get a ball point pen this morning to write a shopping list and it sort of exploded in my hands. As destructible as I am I forgot about writing the list and tried out the broken pen as a clay tool. I got 5 different sized hole to use as punches and the tip to make dots. Besides that the spring can be rolled to make parallel lines or cross hatching. I would like to see what I could do with these tools to make mokumegane but that will have to wait for another day when I have time to play.
