The MK1-Kunai is the standard issue throwing knives for all Tenno.
The MK1-Kunai is one of three Secondary weapon options available to new Tenno, which can be acquired from the Vor's Prize tutorial prologue. The Mk1-Kunai is suited for new players who desire a silent and stealthy sidearm.
While the MK1-Kunai deals weaker damage per hit than the Kunai, it has a slightly higher critical chance and damage compared to the latter.
The Kunai does not have the pinning properties of other projectile weapons, such as the Boltor or Paris, but will simply throw targets backwards upon death.
Bugs
Using Quickdraw on the Kunai can cause infinite reloading issues. (Fixed?)
As with all thrown sidearms, when performing a Jump Kick, your frame will hold the Kunai as dual pistols. Upon hitting the ground and sliding, this will quickly switch back to as it should be. (Fixed?)
When a Hobbled Dragon Key is equipped, sprinting (depending on your frame's speed) will cause the Kunai to be held incorrectly. This also applies to sliding (at slow speeds?). (Fixed?)
Trivia
The Kunai (苦無) was traditionally a multipurpose tool, similar in design to a crowbar. It could be used for gardening, masonry, and other things.
In popular culture, the word "Kunai" is often associated with ninjas and is depicted as a throwing knife.
The MK1-Kunai was introduced as a new starting weapon option in Update 14, alongside the Lato and the MK1-Furis.
