In act I, scene 2, of Measure for Measure, one of the gentlemen uses the word sheer:
Luc. I, why not? Grace, is Grace, despight of all con-,
trouersie: as for example; Thou thy selfe art a wicked
villaine, despight of all Grace.
First Gent. Well: there went but a paire of sheeres be-
Luc. I grant: as there may betweene the Lists, and
the Veluet. Thou art the List.
From ShakespearesWords.com I gathered that sheers is used here as shears, but I still cannot make any sense out of it. Why would there be any shears between soldiers? Is sheers just a friendly term for bladed weapon such as sword?
