Knockback for zombie knife?

[Barbarian]

As I'm sure everyone knows, zombies get stuck a lot on movable objects. Could zombies be given very small knockback on the knife, like maybe 1/20 of a shotgun, so that they can free themselves? I doubt it would be much threat to those barricades humans always set up.
