This is a single length gut core string with a nickel silver wire winding. There is a thin silk under layer wound onto the core between the gut and wire. Because this string is made with a solid nickel round wire, the wire is polished so that the tops of the wire wrappings are smooth. This string is not as smooth as one made with flat winding, but the string feels smooth to the touch.
Because the string is made with round wire and then polished, the tone is quick and bright. The end of the string that goes into the tailpiece is knotted with a loop of gut on the end and the knot is cushioned with a leather washer..
