Ballistic Knife:
A ballistic knife is a knife with a detachable, self-propelled blade that can be ejected to a distance of several meters by pressing a trigger or operating a lever or switch on the handle. Contrary to its name the blade is propelled by the kinetic energy stored in a spring instead of gun powder. It's not a firearm...basically works on similar principal of a springer airgun! But still, it is either restricted or prohibited in many countries

I also checked ebay.com and found that there's one up for grab...but alas without blades!!

Now, my questions to learned members are:
1. Are these knives (ballistic/wasp) just a marketing gimmick or they do offer some kind of advantage over regular knives in self defense situation?
2. Are these legal in India?

Disclaimer: before someone flame me for planning/advocating to use these straight out of comic book knives in real life self defense situation!! Let me clarify, it's purely a theoretical question...I have no intention of buying/using or doing anything with these knives
