People keep spamming this knife ad all over the net but it really is useless.
So, when stabbing it makes a bigger wound that bleeds more? That's not helpful. No, it really isn't. If the victim will bleed to death in a few minutes, what do you think they will do in the meantime? If they aren't incapacitated already they will fight back so you will have to stab them again and again until they stop fighting. And in that scenario it does not matter whether you use this spiral dagger or a cheap Mora, hit a location that will disable the enemy or fight until they bleed out, but "minutes" is a really long time during a knife fight.
Besides, if your aim is to stab someone once and then run away it would be better that the blood stays inside the body rather than comes out through the gaping hole. The blood will cause all kinds of problems with internal bleeding but letting it out is the lesser evil.
Other problems:
a) You can't cut or slash properly and seeing as 99% of the time you use a knife for something other than stabbing motherfuckers this is a downside.
b) The handle isn't good. A perfectly round handle isn't as easy to hold as oval.
c) No added value for the price compared to cheaper knives. (Actually, a screwdriver is about as useful as a stabbing weapon.)
d) The name is a marketing trick, Jagdkommando don't really use it.
