Strivyos

Strivyos are small, specialized daggers that are usually carried by members of the NightOps, especially the Albera division. Able to be completely hidden, they can be activated to form strong blades that can easily hold up against huge explosions, and can easily slice through human skin. They also come with microjets, able to quickly propel the blade at high speeds when thrown. Most strivyos come with their own "functions" aside from acting as melee weapons, ranging from explosives, boomerangs, to even hidden guns.

Usage
Most strivyos are carried on the user, usually hidden within their clothes. Detection of these weapons is nearly impossible, and can only be seen by particularly observant watchers, or if it is placed obviously in the open. In combat, strivyos can activate nearly instantly, forming the blade, usually ranging from 6 to 12 inches. Use of strivyos in fights are meant to be used quickly, often used for killing blows up close or as projectiles. This is why users often carry multiple strivyos at a time, usually with different functions. Meant to be a last resort for Albera engaging in combat.
 * Explosive strivyos are devices that can explode, often when hit by enough force, or when it detects determined enemies nearby. These are often standard strivos, and NightOps operators can expect to have to dodge and point away the explosive, to minimize damage. Some users tinker with their explosive strivyos, such as Aaron setting his to go off only after Meian let go of the strivyo, thinking it wouldn't explode
 * Spinning strivyos are devices that are used for mainly spinning, instead of throwing. These strivyos often come with blades at both ends. Spinning strivyos can lock on to set targets, and can easily weave through most obstacles and defenses. Generally the only way to counter these projectiles is to form total protection with no openings,or to blast the strivyo away. Some users of spinning strivyos can tinker with their spinning device, able to activate and deactivate the function while in flight.
 * TRICK strivyos are devices that have more specialized functions, depending on the user. They often contain multiple functions at once. Aaron's first TRICK strivyo contained elemental fluids, which could generate flames, explosive gas, TAR, and a lethal injection.
