Extermination Elimination is Kay's final weapon, and her main one in most cases. It is a hatchet and hybrid of another axe. She uses this in nearly any situation, being able to swing it with ease. The original name was going to be 'Suicidal Sin' due to it almost being a 'suicide mission' if you attempted to attack her, or even stand near her if she were ever to swing it wildly; however, she found the name to be too triggering, and it best suited her knife, Sinful Shard. While being able to swing it wildly, Kay is well known on the team for being able to lift it with ease, and swinging it skillfully and almost elegantly.
This hatchet has honestly saved her on many occasions.
The appearance of the hatchet is odd for an actual hatchet due to Kay always adding to it, making it more of a "D.I.Y" weapon.
On average, it should (and use to be) 18". However, she extended it to be 23", making it easier for her to gain some extra length with her swings. It's heel of head, bit of head, and toe of head are all tinted purple, with the cheek/ramp, poll and neck all are coated in purple-silver.
The blade is much sharper upon inspection due to Kay constantly sharpening it. Kay spends most her time sharpening it when no one is looking.
The neck, belly, shoulder, toe of haft and heel of haft are all silver, but due to this Kay must wear leather gloves while using it.
She has carved the word 'Eliminate' on the side of it.
While it is small as a hatchet, Kay can extend it further, making it reach a length of 36-40" all together, extending the blade itself. This makes it much heavier, and Kay must swing and wield it with two hands. She can also use this as a shield in a way if needed, using the Pole to block attacks from swords, blades, knives etc.
What does this mean? Well, even though Kay can extend it, she can also subtract it, making it small enough to be held on her belt with her knife. It decreases to 8" almost looking like a knife.
The only known history upon this item that Kay has revealed is that her father gave it to her as she left. She only figured out how to use it once she had her first encounter with the crows. In which she used it to help Isa and give her cover. This is when the two started working together.
Kay has used this weapon the most.
Combining the carved words on her weapons you can create 'Eliminate Sins'
