Impressed that you hold the blank while squaring off the ends! I use a pen jig to hold it. I’ve tried your method and it hurts when the bit catches and rips the blank out of my hand. Thanks for the video
Are you going to attach something to the other end (the end that's exposed when you put the fountain pen in the cap)? I'd put a fabric/mesh stylus on it but that's me. You could even put a paintbrush there. Thanks for the awesome ASMR.
