This is just a very few months from local market testing and less than a year from being massively available, almost anywhere. It will seriously hurt the sale of junk autos and revolvers, and proably almost wipe out the sales of derringers and mini-revolvers.

You can ccw a pair of them in front of your hips, and anothe pair of them behind your hips, and have 6 lethal projectiles, while retaining one such in each hand. I can start, hands on hips, everthing concealed, and put 2 of them on a torso at 5 yds in well under 1.5 seconds, throwing with both hands at the same time. In another 2.0 seconds, I can put 2 more blades into that torso. I am busy practicing doing all this as I charge a pair of targets, placed 20 ft from where I start, 6 ft apart. It's not at all hard to be more deadly with this sytem than ANYone is with a mini revolver, and twice as deadly as anyone who only has a derringer.

NO background checks, no nothin, practice in attic, garage, basement, abandoned building, or thicket, all you want, no further cost at all! Many millions of people, world wide, or going to be quite skilled with this weapon, very soon now. Many will use them to take pistols and AK's from the tyrant's minions.
