Seeing red for all the editing done by my advisor as I learned to write.
My PhD Advisor was an integral part in my development as an academic. There certainly were many drafts delivered back with plenty of red text to fix. In that spirit, I wanted to make a suitable thank you for the years of mentoring so I chose a paring knife with african blackwood handles and carbon fiber pins with a red G10 liner along the spine. Hopefully my later drafts were more reminiscent of this color balance.
