Anyone else have a knife with carbon fiber blade?

Ok, thanks for the correction.
maybe this only pertains to ceramic kitchen cutlery which aren't weapons and law regarding this may be found somewhere else.
Could be wrong about this as well.

What I posted about is the "Undetectable Firearms Act of 1988"

"Undetectable Kiitchen Cutlery Act" shows no Google results. :rolleyes:
 
Bastion website says "Pure all carbon fiber", so I guess there is no metal at all according to the manufacturer.
 
Not carbon fiber, but I have owned a knife made of G10 and I could get in almost knife-like in sharpness with coarse sharpmaker stones. Good for concerts and Greyhound travel.

I know the particular manufacturer puts a certain percentage of steel in their ceramic blades, but because it was mentioned on an American TV program I assumed it pertained to the US.
Maybe it didn't.

Not scales but blade. My brother gifted me a carbon fiber neck knife a couple years back. It is a neat little thing, lite as a feather but mostly a last ditch item. I can't see these being used for much other than a letter opener or maybe opening boxes, and I think even those limited functions might be too much over a long period of time. I've not really used it much, does anyone else have one and what are it's uses and how long will it hold an edge for the above uses? Also, anyone ever sharpen one?

Only legit use I can think of is removing battery wraps from lithium batteries. When wraps get damaged you need to replace them, and using a metal blade can short it and cause it to go into thermal runaway and explode. CF knife would be sweet because it would be non metallic abs sharp enough to cut the wrap but not sharp enough to puncturethe negative casing of a battery .
 
Some ceramic knives do contain metal in the handle even if the metal appears to be non metallic. I'm talking cheapo ceramic kitchen knives.

I believe I read that that this specific one (Bastion 05) won't pass a metal detector, it seems the manufacturer added some metal powder or something to the CF. I have not tested it, but I do have a Schonstat and another metal detector that I could test to see I get a detection on it.

I have seen these carbon fibre edged blades along with g10 ones and the Cold Steel kraton ones as well. Many of them have a little piece of metal hidden somewhere in them just so they won’t be snuck where they don’t belong.

I haven’t owned one but there are many different types at my local knife store. I am not sure which of the synthetics take the “sharpest” edge. Of the blades I checked out it seemed the g10 ones had the finest edge. No idea which will keep the edge the longest.

From what I heard the way these are sharpened with sandpaper. (So it is sort of like trying to put an edge on wood I guess) They might be slightly better than a jail shanks made from snapped lunch trays.

Imho the most feasible looking ones are the Cold Steel Cruciform dagger style.

Since various countries have import restrictions on anything that is both knife-like and undetectable, I would not be surprised if a major manufacturer hedged their bets to keep more markets open to them. Pretty sure both Canada and Australia have import restrictions on that, and I would not be surprised if the EU was similar.

Isn’t carbon fiber electrically conductive?

Well I haven't tried it I just assumed it wasn't, I don't think it'd short a battery since its not metal but if someone could correct me if I'm wrong id appreciate it. I've just been using a plastic shiv for my battery cutting needs :)

The only requirement in US Code dealing with non metalic weapons has to do with firearms.

A firearm must contain 3.7 ounces of stainless steel to be legal for manufacture,sale, or importation.

You are welcome to search the US Code (it's online) to check on your memory of the tv show

All firearms, or just nonmetallic firearms? An aluminum ar lower has no steel but is a “firearm.” Likewise, I’m not confident that polymer lowers contain steel inserts...

This is the one time the feds don't consider the reciever the firearm.

It must be a major component, like the barrel, slide, cylinder, bolt etc.

The Act of 1988 has been modified several times as technology changes. I havent had my FFL in over a decade so I am unsure of its current language.

That punk pulled a Glock 7 on me. You know what that is? It's a porcelain gun made in Germany. It dosen't show up on you airport X-ray machines, and it cost more than you make here in a month.

If you don't own one CIA Letter Opener you don't own enough CIA Letter Openers. They made excellent tent pegs way before the current lightweight EDC craze.
 
Our EOD guys used to be issued a small ceramic folding knife with a CF handle. Not a bad little cutter, but steel gets sharper. The biggest issue was the ceramic blades would snap with any lateral pressure on the blade and chip out when they hit hard materials (like thick copper wire....). A novelty for sure.

As for other non-metallic knives, I owned (think I still have it) a Mad Dog frequent flyer in ceramic, that thing never took a good edge. In order for the edge to stand up to the abuse that they used to tout, the edge had to be so thick as to be ineffective as a cutting instrument.

I have handle a few G10 knives at local gun shows and BLADE show, and, while interesting as a back-up concept, I just don't see the appeal. They sell and will take a skin cutting edge, but lose that edge rather quickly.

I think your CF knife was a very thoughtful gift, and a unique conversation piece.
 
Also keep in mind that US airports (and most major International ones) do not use simple "metal detectors" anymore, and haven't in at least 2 decades. Even a "non metallic" blade will be found.

I never got any of these "undetectable " weapons , mainly because I was afraid I'd get so used to carrying , I'd forget it was on me . Then be in big trouble if it was discovered within a high security area . Plus , I can always carry my cane, which is better anyway .
