You _can_ refine any sword at any time, but if you don't want your refining to go to waste, you should wait until Higekiri reaches Toku San (level 75) and Hizamaru reaches Toku Ni (level 50).

On the other hand, it takes a long time for them to get that high. And one of the daily missions is to refine swords two times (the reward includes a help token!). So if your other swords already have maximum stats, you might as well refine Hige or Hiza a little bit just to complete the daily mission. I

(By the way, even if your swords have maximum stats, feeding another sword to them in the refinery still counts for the daily mission.)
