Hi Ed It looks like the groove for the string isn't wide enough, and has a sharp top edge which is cutting into the string. Ideally the nut grooves should be wider than the string diameter, so it touches only at the bottom and the grooves only guide the string and do not offer any friction along the string length. So if possible you could try to gently widen the nut grooves with a fine round diamond file, then polish with a thread of twine dipped in polish compound. Or if you have a friendly lute maker, he or she can easily sort it out. Hope this helps - Luke

Has anyone seen similar wear patterns? Does anyone have any suggestions as to how to save the second string that looks like it could break at any moment? I made a video with two pictures. The first picture is from the front, the second picture is from the pegbox side and has the replacement string in place. Thank you in advance. Here is the video with the two pictures: [1][2]https://youtu.be/pPr6bilW26A Ed Durbrow Saitama, Japan [2][3]http://www.youtube.com/user/edurbrow?feature=watch [3][4]https://soundcloud.com/ed-durbrow [4][5]http://www9.plala.or.jp/edurbrow/ -- References 1.
