Is cross upset being cut? (7)

I believe the answer is:

scissor

'being cut?' is the definition.
(I've seen this in another clue)

'is cross upset' is the wordplay.
'upset' indicates an anagram.
'is'+'cross'='iscross'
'iscross' with letters rearranged gives 'SCISSOR'.

(Other definitions for scissor that I've seen before include "Carved" , "Cut with two blades" .)

I've seen this clue in The Globe and Mail.
