<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sword cover</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sheath that I've seen before include "Close fitting dress" , "Cover for a blade" , "Cover for a sword" , "Protective covering for a knife" , "Protective cover" .)
