I am surprised how well this plastic nut is made, its tempting to retain it. I have woolly mammoth tusk here and cow bone, i think i might make me a bone nut, the wooly mammoth can wait for the Ancient Kauri bodies i am yet to do.
The thing with a nut is, once you fret the guitar, the nut is out of the equation, but a well made nut also means less chance of cracking and breaking it.
