Fabulous! I've made one pen from black limba and found it to be such a fascinating wood, but I think accent use is the perfect use case here. It looks incredible against the cocobolo backdrop. Posts like this make me want to get a CNC or laser engraver or something.
Thank you, guys! Andrew, it's pretty addictive and certainly another rabbit hole. Here's a pic of a blank with one v-carve and insert already in, then a second section carved with the plug of different wood ready to glue in.
