A way better Knife Zealot
 Veteran Build - Warhammer 40k: Darktide 

Exe Stance is actually a genius 4head play. You see:

• Finesse knife does a stupid amount of damage. Punch-light headshot stabs are lethal (punch applies bleed lol) you can one shot mutants from the back or to the head, crusher and bulwark backstabs clean them up and are easy to reach with knife dodge... You're more fragile than a knife zealot (!!) but more dangerous.
• Weapons Specialist rounding up on revolver ammo means you never need to reload. Just quickswap, activate Agile Engagement on whatever, continue stabbing. You activate +25% damage from Agile Engagement on demand. There is no breathing room you are always up.
• You're extremely mobile and extremely fragile. However, knife zealots don't die to damage. They die to silent trappers, dogs, and bursters popping through doors. Situational awareness is worth far more than Unholy Revenant - and you get wallhack twice a minute and can even share it with your team!

So you use executioner stance on cooldown to glance around at what's coming. This saves enough points that On Your Toes can restore your Toughness. It's not as good as Voice of Command's overshield but VoC is pretty overtuned and the wallhack spam is pretty unique. Absolutely no points left for Tactical Awareness - and that's fine, we wouldn't want to burn 2 on a utility move.

Knife blessings are pretty set in stone. Revolver can be whatever - Hand Cannon is nice because of the bug where it applies to melee crits, though this build only benefit from it on front-stabs due to Ruthless Backstab. Stamina curio might be unnecessary, I just happen to have a good one that goes on all builds.
