Respectively those items would be:
There is no reason this could not be manufactured today:
Gyroscopic Mine – A thrown, puck-sized, radial dispersing, projectile mine. When thrown, the gyroscopic aspect insures a horizontal deployment of the projectiles that are stacked in three rows about its circumference. Trajectory/elevation sensing is used to insure detonation after a timed delay, initiated by the course change at the apex.

This would take a lot of unsuccessful technology to finally be worked out (obviously in secret) being the magazine held power cells and the rail-gun technology:

Her body-armor plates are purely fictional, yet I add in hopefully enough 'weird' info (the technical term is BS 
) that they make for a 'possible' what if?:
Glow Hide ~ Processing:
"Glow Hide" is made from thick dermis bovines, killed at a particular range from a thermonuclear blast. Resulting from a precise combination of heat and radiation exposure, the hide must be removed, gleaned, and worked (cut and formed) within specific time constraints.
Though the exact calories (heat), and coulomb/kg or roentgens is not known, what is known is as follows. The flash must convert the epidermis to ash and the grain layer of the dermis must experience a 1.6-2.4mm char. The hide must remain intact upon the carcass continually irradiated at fallout levels for 10-16 days, though the ideal harvesting time is between 12-14 wherein it swells and thickens 3.6-5.4x.
Once removed from the carcass and out of the radioactive area, remaining flesh (meat and fat) must be carefully scraped away. The item cut to final shape, thinned (flesh side) if required, fastening inserts added, and formed to shape within 3-days wherein the pad sets, no longer able to be worked.
The grain layer will continue to thicken and harden 1.8-2.6x below the char. The corium layer will continue to expand in thickness up-to 3x and provisions must be made for the expansion along the edges (cuts typically made –30° to the flesh side). The green hide must then be allowed to season for an additional 5-7 days, wherein the transformation-process is ceased and the hide tanned in a common chromium-sulfate solution.
The resulting grain layer should be virtually impenetrable with a surface hardness of Rockwell "C" 57-61, though remains semi-elastic. The lattice of the corium layer will compress, distribute, absorb and dissipate impact retaining its elasticity and spring-back up to 38%. Beyond that limit the lattice will remain permanently compressed. Exact energy absorption figures vary to such a degree that a range of data cannot be established.

Finally the low-tech to pull it all back:
(2) ~ Telescoping Thai Dha-Shay Sword ~ Custom Manufacture:
12-inch gently curved knurled aluminum oval-tubular grips house a 3-section, 22.5-inch x 1.25-inch telescoping blue/spring steel dual-leaf blade.
Each 11.5-inch section extends 7.5-inches past the following with the remaining 4-inches captured between the leaves of the following section for attachment. Each section is made up of two leaves resulting in two opposing chisel edges with the tip section forming a single edge. Squeezing together the leaves at their trailing end and slipping them back past the catch point, then rapping the butt of the grip to slip them back into it manually performs retraction.
Though considered an inexpensive and disposable weapon, the blades may be re-sharpened indefinitely until reaching the alignment/catch grooves. Although the blade may be progressively extended (7.5, 15, 22.5") to be utilized as a knife or shorter weapon, there is no provision to retain the trailing pieces to prevent their extension past the spring pressure.
