I made this a couple years ago for my daughter. I think the main plank is padauk and the inlay I know is purpleheart. I just used a hand chisel for the finger grooves and sanded them down to a smooth 300-grit finish. Lots of sanding. Lots. I just coated it with 4 or 5 coats of high-gloss poly. The wood was originally scrap but the knot on the end of it was begging for a nice project. Once I cleaned up the knot, I saw this scrp’s purpose immediately. Unfortunately I don’t have any pics of the front side after I applied the finish.
