They don't have a weapon but how about more than 1 knife? Stick a knife in one, then leave it there while using the other. It's faster although there's a risk of the 1st person being able to pull it out and use it on you...which might have been done.
“In a time of deceit telling the truth is a revolutionary act.” ― George Orwell
It's not over when you lose. It's over when you quit.
