Cestus

Structure
The Cestus consists of two main parts- the part that goes over the user's fist, and the part over the user's wrist. The fist part performs the weaponry's function, which is essentially to punch the opponent into a bloody pulp. Usually, a Cestus will have spikes, and is certainly always hardened to ensure maximum damage. The wrist part is to assumingly protect the user's wrist, but it also serves as a shock absorber from when the user swings at their opponent. Furthermore, this part is for a nice fitting, securing the weapon itself onto the user's arm. The wrist part (the inside) is padded, to ensure that the user isn't injured while equipping the item.

Uses For Combat
Cestus's were commonly used for arena-based conflicts, but also make use as a fallback weapon for when one is disarmed. In such arena matches, usually the fighters were slaves, or otherwise those who weren't supplied with weapons. Cestus matches were brutal, bloody messes of boxing and wrestling, except to the death. One blow from a Cestus could easily knock someone unconscious, if in the right area.

Crafting
A Cestus is easily crafted, being the basic weapon it is. A simple, handmade Cestus is fundamentally a glove with studs on the knuckle area, the studs usaully made of cheap metals such as iron or bronze. If not with studs, then with hardened leather, just enough to make it hurt.
