Hi Jon,
I didn't think about the word culinary, I'm sorry.
The little grooves at bot ends are just for decorative purpose, I made them, burning with a wire, while I was on the lathe.
I Just cleaned up the cylinder on the lathe and finished properly both ends with the rounded edge. So I couldn't refrain from adding some personal decoration ...
Actually, it is prone to catch flour and dough, I just took the picture in the kitchen while my son was doing some pastries.
(I guess we will eat something good tonight :oP )
