Not sure about this but just a simple idea:

Weapon length : 61
Weight : 5 (2.5 per one heavy throwing hammer)
Accuracy : 99
Difficulty : 8
Speed rating : 81
Max Ammo : 2 (a second chance to hit someone, or another chance to knockdown if didn't occur)
Slots : 1
Blunt damage : 40 (believe me it's not more powerful than a jarid)
Has no bonus damage against shields unlike many
Knockdown or at least stunlock (the stun which polearms does)
Secondary mode:
One handed
Melee damage : 27 blunt
Speed rating : 97
has no thrust attack
Knockdown
The very first one:
