Rus has nothing to do with the current definition of Russia: Rus were Normans . 
In the 13 century “ Russia’ as a state did not even exist: there were smal solitary city-states ruled by local princes who were all ( except the North) vassalls of the Golden Horde. Local swords were Norman , changed to Mongol sabers, and Peter I tried to convert Russia into a part of Europe and tried to rearm his army with European weapons.  The Cossacks armed themselves with Ottoman and Persian sabers. In the early 19 century,as a result of Russo-Caucasian war, shashkas were introduced: aristocracy, royal family included,  were prone to carry real Caucasian  shashkas, but for the unwashed masses a saber was created and called  
“ shashka” despite having nothing common with the original one. 
 Thus, Russia as such never had a truly national, original sword.  Even in the 13 century:-) 
As to the sentence you ask about, open the Elgood’s chapter and re-read it.  Hopefully, it will help you clarify its meaning.
