So yeah, another vambrace, this one much lighter and better drawn than the other one, and once more, I shall copy from other places I have uploaded it to explain the mechanisms and such.

"A) The retracting "switchblade." Hydraulically powered (c), once activated (d) it is deployed by angling the hand and wrist downwards (g): this prevents accidental activation outside of combat. It's not designed as a principle melee weapon, and is more of an off-hand weapon. It may still be a vibro weapon, or at least on the tip. I'm a little worried about how flimsy this feels compared to Version 2.
B) The force blaster. I've went with an actual force-field firing weapon, since Nick uses another bit of forcefield tech as a shock absorber, so I know he's got it available. Basically, it's a mathematically-defined barrier that can be adjusted in power and range. It is powered by the rechargeable power cells (E). In addition to the methods used to activate the switchblade (except angling the wrist up), the force blaster uses the duster-mounted trigger (F) to fire it. Again, worried about flimsiness, may have to go back to version 2 on this. I might end up replacing this with something simpler for Nicky's first version, but my idea is that eventually this becomes a full-on forcefield manipulator system.
C) The hydraulic system that deploys and retracts the two weapons, mounted on the underside. It's fairly simple but powerful, and power is supplied by the top-side mounted power cells. It's controlled by the selector switch (D).
D) The selector switch. It has three settings: blaster (turned to the inside), off (set to the middle), and arm blade (turned to the outside). This is a somewhat unwieldy safety mechanism, and I'll be working on a better method for the next in-story version.
E) High-capacity power cells, these are more likely to be capacitors because the force blaster needs quick bursts of power, unless I use these as batteries and give the force blaster its own capacitor.
F) The thumb trigger, mounted on the knuckle duster. Mainly designed for firing the force blaster, it can be used to deploy the arm blade.
G) The wrist switch that I didn't really draw attention to in the last version. This is a pressure switch that helps to activate the two weapons. When the hydraulics are off, the wrist can move freely. When the arm blade is activated, angling the wrist downward triggers it and lets it slide forward: this keeps the hand out of the way while being used. When the blaster is activated, angling the wrist up deploys the force blaster and helps it fold into the palm for easier firing. Again, somewhat complicated, but I like the safety device so I'll be retaining it in a few future in-story versions.
H) The only reason I'm calling this out is because I forgot to include a means of putting on or taking off the vambrace last time. This time, the whole set of crap is attached to a piece of good tough leather by grommets, with a padded liner sewn in for comfort. By making the vambrace leather, I can let Nicky adjust it for his comfort or age if he needs to. The thing doesn't actually open, it just loosens so you can slide it on or off. The laces running up the inside are for tightening it or loosening it as he needs. The kinetic blaster is attached to the vambrace by a series of straps, so it can be adjusted with the rest of it."

And since this is long enough, I'll just leave it here as is. XD
