ok i know I am still an amateur. but I decided to repair a pen I made 5 years ago. by repair I mean I turned a new top half. bottom is cocobolo and the top is ebony. I sold this pen some time ago and the cap end cracked. so the customer told me what he wanted and when I gave it back to him he seemed very happy. even asked if he owed me anything. of course I said no. but was tempted .
