Um... anyone who carries keys has equipped themselves to kill someone.
Anyone who lets their fingernails grow has equipped themselves to kill someone.

It isn't ownership of the knife, but rather possession at the time of use. It is the intent to use it... and either party can be guilty of that - either the one that had it on them at the start of the altercation, or the other person if that person is able to get possession of the knife.
