Homemade Weapons for STZ2E

I am making a setting for SURVIVE THIS!! Zombies! 2nd Edition and I wanted to include some homemade and makeshift weapons. Here are a few I've come up with.

Lawn Mower

While it can be quite unwieldy, a push mower can be a deadly weapon and shield.

Damage 2d6, ROF 1, Range —, Ammo —, Weight 90, Cost 160

Note: Must use two hands to wield, attacks made with disadvantage, face-to-face attackers must make DC 10 Dexterity check or take 2d6 damage when taking wielder

Lucy

A Lucy is any large bludgeoning weapon that has been reinforced with nails, bolts, barbed wire, or other metal to make it particularly brutal. The name was coined by a particularly brilliant, but vicious survivor leader. 

Damage 1d6+1, ROF 1, Range —, Ammo —, Weight 5, Cost Special

Note: Lucies have a base cost of 10, but must be specially crafted. Each one is individualized by its user. Any non-zombie hit by a Lucy, must make a DC 10 saving throw or suffer an additional 1 point of damage on it’s next turn from bleeding.

Makeshift Sword 

Any large blade can be turned into a weapon, be it a paper cutter or a lawnmower blade. They are easier to attain than a traditional sword, but also break down faster.

Damage 1d6+1, ROF 1, Range —, Ammo —, Weight 5, Cost 10

Note: Unlike other swords, these have a usage die (which starts at d10).

Potato Cannon/Spud Gun

These simple ballistic weapons can be created from a variety of pipes and either pneumatic force of flamable gas. Unlike most firearms, ammunition for a potato cannon is whatever you put in it.

Damage 1d6, ROF 1, Range 500, Ammo —, Weight 5, Cost -
