Intent: To create a personal warhammer for [member="Dor'Fix'It"]
Development Thread: If Needed
Manufacturer: Rusty's Custom Firearms and Cutlery
Model: The 40k (because it weighs 40 kilograms, of course)
Affiliation: [member="Dor'Fix'It"]
Modularity: No
Production: Production: Unique
Material: Faux wood, durasteel, tungsten, triggering mechanism
Classification: Warhammer
Size: Two handed
Length: Haft- 1.75 meters/Overall- 1.9 meters
Weight: 40 kilograms
Special Features: When loaded with the proper explosive cartridges, impact of a sufficient velocity will trigger said cartridge, sending a tungsten spike shooting into the target.
Description: It is a massive hammer, scaled appropriately to the customer, who is a massive fellow. The haft is a solid durasteel core wrapped with a faux wood veneer that is stylish, moisture wicking, provides excellent grip, and is antimicrobial.
The head started life as a solid billet of high strength durasteel. It's been milled out to accommodate a channel for the tungsten spike, as well as a simple impact triggered firing mechanism. When the user strikes something solid with enough force, the impact triggers a cartridge loaded with a small explosive charge that sends the tungsten spike shooting out with enough force to punch through light to medium armor.
Because of the weapon's size and weight, it cannot be wielded by most baseline humans. Even those that could swing the thing would likely find the use of the spike beyond their abilities. Even the intended customer is likely to find the sheer mass unwieldy. Though a swing and a hit will be devastating, a miss is likely to result in extreme strain to the customer's arms, shoulders, back, legs, and any other body parts that might be used in the process of trying not to end up pirouetting around the battlefield like a pretty pretty ballerina.
Though the spike is a powerful asset, it must be manually reset in between uses, a process that can take several minutes. And trying to use it against something it can't penetrate could potentially cause catastrophic damage both the the weapon and customer.
