Non-magnetic knives

Actually, scientifically speaking, that's a misnomer... but you all know what I'm talking about. Injected plastic "knives", CF knives, titanium, ceramic, whatever, as long as it won't tip off a metal detector. My brother and I were having a discussion about a maker (forget his name, but he came up in a discussion about Fred Perrin) whose stock in trade is totally non-ferrous laminated CF and titanium (carbide cutting edge) knives.

My brother (a dyed-in-the-wool pinko leftist) said that anything that blatantly designed to get around a metal detector should be illegal without permit, like auto are in most states. Ignoring the politics, are specifically non-magnetic knives restricted or illegal in any way?

Was Warren Thomas the maker you were thinking about? He makes some pretty cool stuff. :cool:

I'm not entirely sure, but I think California has restrictions on 100% non-magnetic knives. I've heard that's why the Cold Steal ninja spikes and the like come with a little metal keyring attached from the factory.
 
Yeah, Warren Thomas sounds like the right name. I also had heard about the California restriction, and the consequent action on Cold Steel's part.

What was Cold Steel's action?

Why do these things exist anyway?

It only can be for a bad use.

I tend to agree with you. I suppose I can see the need for a knife-like object that is immune to the elements, but I somehow don't think that's what these things are for. I hate to say these things are "bad" and should be illegal, but it's tempting to say that.
 
There are many advantages to titanium and other non-magnetic knives, but few of them will be seen on a day to day basis by most people. The same can be said about silencers, they have their place, but it can be said not in the hands of private citizens.
 
I like the look of the Karambit and am looking for something in that style (wich is the same thing, but made of steel, Steel Tiger coming up!)

People told me about these nightshade, the most usefull thing to do about them is to grind them and use them as trainers.

I have my opinion, but I still am open to yours.

Do you see any good sides to those? Is there really somewhere you need a non-magnetic knife?

Do you really think it's a good thing that some people can buy a non-magnetic knife on the Internet and then take a plane?

Remember 9/11?
 
First off, the Mission titanium knives are basically sold to those people who need knives that will not set off magnetic triggers on explosives or conduct electric currents. Some of these are valid uses for civilians. Secondly, titanium makes a very good diver's knife, or so I have read, as it is utterly resistant to salt water corrosion.

THe hijackers got away with what they did on 9/11 because their operation was a paradigm shift. Up until 9/11, the practice in a plane hijacking was to co-operate with the hijackers in order to get out of it alive because that was how it had worked out in the past in the great majority of cases. Now, all bets are off. Remember what hapened on United Flight 93 and consider that the archetype for future passenger reactions to attempted takeovers of airplanes. People in this Forum may call Americans "sheeple" and other names but, when push comes to shove, Americans are not stupid and they will act to protect themselves and their fellow citizens. Remember also what happened to that idiot shoe bomber. I, personally, would think it better if people were allowed to carry folding knives of up to 3"-4" length onto airplanes as that would make them that much more effective in resisting future hijackers. And future hijackers should know it.

Agreed, I can understand for titanium blades, but when we talk about nightshade series... look at those, they are not made for a civilian job!
Push dagger, tanto, karambit.
 
I was talking about all non-magnetic knives and titanium knives, probes, tools do have certain EOD purposes along with being rust resistant. I wasn't specifically referring to knives to get through metal detectors. I haven't seen the nightshade series of knives I'm assuming they're sharpened G-10 or carbon fiber or the like?
 
So-called metal detectors and x-rays work on 'seeing' density of the object, not the material.

Metal detectors and x-rays are two completely different things. Metal detectors create a magnetic flux which is modified by any magneto-active metal mass passing through it, proportional to the metal's mass. If the metal doesn't react to a magnet, then it won't set off a metal detector (titanium being a good example) X-rays work on radio-opacity, just like human eyesight, but shifted over a good bit in frequency/wavelength. Just like glass is solid and dense, but still transparent, there are plenty of materials (carbon fiber) that are solid, dense, opaque, but not radio-opaque.

I'd have to politely disagree here. Silencers can prevent permanent hearing damage if you were to discharge a firearm in a confined space (such as your house). Additionally, they would eliminate the noise residents in close proximity to firing ranges often complain of.

I rather doubt that many criminals would be all that attracted to silencers anyway, seeing as how they nearly double the total length of a handgun, and concealment is usually a paramount issue. It's illegal for felons to carry a gun anyway, so the current illegality of silencers in many states shouldn't be counted on as a deterrent. When guns are outlawed...only outlaws will have guns.

I hate getting into that angle of things but honestly, if terrorists really want to bring some sort of improvised weapon on a plane, they are going to. I personally thing they would stay away from anything with a traditional weapon outline, so that when things are passed through the checks no flags will be raised. At this rate every bic pen is going to be scrutinized in the coming years.

I really like the work Warren Thomas does. It's unique and unrivaled in the industry. Joe Brum makes knives that are completely g10 or Carbon fiber, and some of his are really beautiful pieces. How does the saying go? If these guys aren't allowed to continue making knives as they could before, then the terrorists win, right? I understand the realities of making things of this nature, and I understand the need to safeguard ourselves(I agree), but it's the disruption of the American way of life that the terrorists are hijacking the most.

I am in no way trying to offend anyone here or start any arguments(or get too political). This is just my $.02, your opinion may vary.
