Use the Knife to Save Ammo

Just like your fists, the Knife does not use ammo and thus is a great weapon for saving ammo on your other weapons. Best use the Knife to take out isolated zombies or thin out hordes one zombie at a time.

Though the Knife does not use any ammo, it is worth noting that Ammo Mods will apply normally to its slashes.

Use the Knife with Omnimovement

Zombies swing quickly when you are at an arm's reach of them – but so are you quicker with the Knife. Slides and omnimovement are your best friend when trying maneuver around zombies or hordes.

Knife is Not Recommended for Bosses

When fighting a boss, it is best you focus on using your primary weapon instead since the Knife will severely lack in DPS against them. Bosses like the Abominations are huge bullet sponges and will take a lot more punishment than an ordinary zombie.

Gives Less Essence than Headshots

Kills with the Knife are counted as Zombie Melee Kills and give only 105 Essence compared to 115 Essence from you can get from headshot kills. If you are looking farm Essence, go for shooting the head instead.
