It's not enough to be able to pick up a sword. You have to know which end to poke into the enemy.

Our reading
An editorial interpretation.
Lifting a sword isn't sufficient, the speaker jokes; you also need to know which end goes toward the enemy. It's deadpan humour about the gap between owning a tool and understanding it, with the obvious made absurd by treating it as real expertise.
