I have a question about the engraving on the tabako-bon I'm hoping you all could answer. I was concerned the writing was made by a rotary tool of some kind due to the way the carvings have a scalloped edge. I've been able to take some closer pictures and it does not appear to be a rotary tool (the bottom of the carvings are not smooth and some of the areas come to a point). Indeed, the width of the carvings is very thin. It does not look like it was carved with a straight blade or chisel either. If I had to guess, a small circular or semi-circular gouge of some sort. Note the valleys coming off of the scalloped edges into the bottom.
Have you all seen this before? Any ideas what tool was used?
Thank you for looking.
Regards,
John C.
