Axe of Chi

The Knife of Chi, also known as the Last Knife (both terms are interchangeable with blade), was a powerful weapon first formed in Olliverse Alpha. This knife, influenced by Stratosfear, had the ability to grow increasingly powerful the more lives it claims. It also had the ability to directly obtain the abilities of other blades. At its peak, the Knife was able to effortlessly slice a human in half.

The Knife was originally nothing more than a chef's knife in Hellven. It was first used as a weapon when Alfred Oliset murdered a civilian using the knife. Because Alfred was influenced by Stratosfear at the time, the knife became influenced by Stratosfear as well, giving it its well-known abilities. Alfred Oliset was highly infamous for using this weapon, but eventually Stratosfear obtained the weapon for his own using.

A counterpart of this weapon exists known as the Gammablade, or the First Knife, weld by Alfred Setoli.

Description
The Knife of Chi is a chef's knife made of iron, rusted and stained due to exposure to the elements. Its handle was originally composed of oak wood, but because it has worn down significantly, the handle was replaced with an unknown material, whose texture is described by various entities very differently. Some entities describe the handle material as rubbery, while others describe it as fuzzy. Alfred described the texture as rough, while Stratosfear described it as "hard and smooth".

When its abilities are used, or an entity is about to be killed, the Knife glows a crimson red. Otherwise, the Knife does not emit any glow.

Oliset's reign over Hellven
In Hellven, The Knife of Chi, as a chef's knife, was made the same way as any other chef's knife. Eventually, a civilian bought the knife from a store for their cooking. The civilian would be killed by Alfred Oliset, using said chef's knife as the murder weapon. Upon doing so, the chef's knife was influenced by Stratosfear, bringing forth the Knife of Chi. Initially, it was a rather weak weapon, but as Alfred claimed more lives, the knife grew more powerful. This weapon was used by Alfred during his reign over Hellven, who personally executed those against him using the weapon.

The Knife was used in the Dual of Balance against Beta Omicron, Khakis Flora, Ophelia Oderfla, and Damascus Ferrum. The quartet defeats and banishes Alfred, but not before he kills Beta, who was taken with Alfred as he was banished.
