who needs a sharp pointed plastic knife??

Self defense weapons that can be kept in harsh environments. For example, stuck in a flower pot outside or in your toilet tank. Other than that, not much and you'd have to be pretty paranoid to put plastic knives in your flower pots.
 
There are plastics and then their are plastics . To me acrylics and polycarbonates are all plastic . I am sure some chemist somewhere is cringing . Impact resistant polycarbonates would make a wicked self defense knife . Prisoners have taken garbage bags melted them down and molded themselves knives . I guess its a matter of necessity and available materials .
The practicality of a plastic knife would depend upon circumstance . I wouldn,t mind exploring just how well I could make and use a plastic dagger of some kind .

... or in the shower, or the fridge, or the ice cube bucket, or between the cushions of the sofa, or CD rack, or in the cupholder in the car, or under your pillow...

There are so many places to keep them, you should buy them in 12 packs! Buy them while supplies last!
 
Sure there's a market. All of them are members of the Super-dooper Secret Mall Ninja Society of the Apocalypse.
 
I may not be well-liked after this but...
one or two places I can think of for "plastic" knives would be:as a bodygard taping one to your person as a last ditch,don't rust weapon;sewing it into your clothes (coat-jacket etc) for same reason;sneaking it onto a plane when doing undercover work (as a spy)

at any rate they're cheap and if they break en-so? but mind it's more of a "I will most likely need to kill somebody" kind of thing...for day in,day out stuff it's useless.

Let me clear this up for everyone. A "sharp pointed plastic knife" is a very useful tool indeed. I am specifically referring to commercially-manufactured "plastic knives". These "knives" may be manufactured from a variety of petroleum-based synthetic materials which fit under the broad category of "plastics," and are intended for use in situations where self-defense is necessary, but where the presence of objects constructed of ferrous metals is prohibited or impossible.

Given this information, I was able to determine three situations in which an individual would require a "plastic knife."

1) - An individual finds it necessary to pass through a metal detector with a concealed weapon.
2) - An individual is working in an environment where a self-defense weapon will be routinely exposed to the elements or submerged in water.
3) - An individual needs to protect himself from hordes of ninjas while operating an MRI machine.

There is also a distinct possibility that the individual simply derives pleasure from the "wow" factor associated with the possession of a "plastic knife." For example: The individual who possesses the aforementioned "plastic knife" displays said knife to a simpleton or "idiot" who has never seen a "plastic knife," whereupon the idiot proceeds to proclaim his/her sheer and undying astonishment at the mere existence of such a feat of engineering ingenuity, and promtly announces: "Wow man. I got ta get me one of those!" Hence, the "wow" factor. :D

I hope this has answered your question paulwesley.

Keep in mind that if you're going through airport security and the detector beeps and it's your pocket knife carelessly forgotten in your jacket pocket, they'll likely take the knife and send you on to your flight. BUT, if you get selected for the random patdown search and they find a plastic knife obviously designed to evade the metal detector, then you might as well call the airline and let them know that they can release your seat 'cause you've got some 'splainin' to do... downtown.

The same would be true in a courthouse or other "secure" installation. It's one thing to carelessly forget a conventional knife in your pocket. It's quite another to deliberately try to carry an exotic concealed weapon which is deliberately designed and which you clearly intended to evade security detection.

I don't know about the Ninjas; as far as I know, there's no way to protect yourself from them... we are all defenseless against them. But, the MRI machine raises interesting needs. And not just medical MRI machines, but anyone working around scientific and industrial nuclear magnetic resonance spectrometers. Indeed, any machine with a powerful magnet or which might be affected by a large piece of metal; perhaps, for example, someone working with a sensitive magnotometer.

Someone who works with explosives or around flammable materials is another person who may want a plastic knife. A steel knife can make a spark and if you're working with alcohol or gasoline or something like that, an unexpected spark while you open the bag may turn your regular chips into barbecued.

Well.... if I was a terrorist.......

Like I said, these "plastic knives" are intended for use in situations where self-defense is necessary, but where the presence of objects constructed of ferrous metals is prohibited or impossible. I'm just telling you what their purpose is. It's is up to you to figure out the reason why someone would wish to use them.
 
i think some knife collectors approach them as a novelty, some would buy them because they are invisible to low tech metal detectors ( they like to be armed in a nightclub, correctional officers), because they "need" a low tech, low cost, last ditch, throw away self defense weapon like the Cold Steel FGX Cat Tanto for stabbing.

Say you sometimes have to walk thru the most dangerous part of your city, with a high possibility to get mugged or attacked, and you have no CCW or you can not get one, and you don't wan't to throw away your 400$ Sebenza because you used it in plain vieuw to defend yourself or scare away the hood rats?

I know this sounds weird, but what if you are a delivery guy for a liquor store and you drive around at night with a cargo of booze and smoke in your van? A plastic knife under your seat would be better then no knife at all.
And when caught you could still claim it is a toy knife
