Scarves [(skahrvz)] "connecting joint," 1276, probably from O.N. skarfr "nail for fastening a joint." A general North Sea Gmc. ship-building word (cf. Du. scherf, Swed. skarf, Norw. skarv), the exact relationship of all these is unclear. Also borrowed into Romanic (cf. Fr. écart, Sp. escarba); perhaps ult. from P.Gmc. *skerf-, *skarf- (cf. O.E. sceorfan "to gnaw, bite").
