Tears in a macro sheet of graphene

[cephron]

If one had a large sheet of graphene (as in square meters--but not necessarily a monolayer sheet) which was then puctured/torn by a blade, how would the tear react to lateral tension parallel and perpendicular to the tear? Would it "unzip" easily under perpendicular tension, or would the endpoints of the tear bear strain before giving way further?

(If this is a totally unanswerable question due to lack of data, I understand. Thanks anyway! xD)

Closest thing I've found to an answer so far is this, which at least gives precedent for why it might come apart in an "unzipping" fashion:
