Watatsumi Koke

Introduction
Watatsumi Koke are a set of 3 knives from the Dontou set of folding knives. The Handle is made of kairoseki, and has various tiny mist dials in it to release mist for Unda and her fighting style. The blades have been infinitely fractalized and thus can slice through mostly everything effortlessly, but due to their small size cannot leave large dents, however it allows for a surgery like precision and cutting power.

Abilities
The folding knives as mentioned previously are incredibly sharp, and are also surprisingly sturdy, being made from the scales of a legendary sea king, coated with a resin that protects it from both temperatures and the passing of time.

Because of how knifes skills work in contrast to sword blades the knifes are incredibly light to allow for an high maneuverability and a easier and more comfortable way of holding it, Watatsumi Koke can be wielded by a baby without so much as wasting any effort, despite being filled with dials inside. The lightness however does not mean they are weak, they can withstand a lot of damage, however the lightness does come at a cost, lack of pushing and destructive power.

Because of it's sharpness and small precise blade Watatsumi Koke can make wind blades that move at speeds that reach mach 2, the slashes grow slower with size. The slashes are also silent and deadly to go with their speed, this means that an experient knife user can possibly even snipe with quick thrusts of the knife.
