How are ceramic blade knives detected through airport security
Best Answer: By the metal pins used to attach the handles
If you're sending it through the X-Ray machine, very easily. X-Rays are blocked by things that have high molecular weights. Most ceramic knives are made from Zirconium Oxide. Zr has a molecular weight of 40. Much higher than the 26 of Iron, the principal component of a steel knife. Another common material is Aluminum Oxide, but these are stabilized with Zirconium or Yttrium (39), making them easier to detect.

the tiny springs are made from Beryllium Copper to eliminate any magnetic signature. Its handle is made from fibre resin and the razor sharp, partially serrated blade is made of 33% glass fibre Nylon 66

Non-metallic, high-tech materials
Some of the most common non-metallic high-tech materials manufactured and used in the making of knives are:
* black woven graphite composite: so hard it has to be cut with a diamond-tipped blade, using water for a lubricant
* carbon fibre sheet - Immensely strong crystalline filaments of carbon in resin
* celluloid - transparent plastic made from camphor and nitrocellulose
* delrin - a very strong, pure white, plastic material used for knife handles
* kydex - a very strong and sophisticated acrylic-PVC alloy thermoplastic material... ican be heat-moulded, sawn, ground, milled and polished and may also be joined to itself or other materials with an unbreakable bond using a hot glass welding technique
* neoprene a rubber-like compound used as a non-slip knife handle grip
* polyvinyl chloride (PVC) - a durable plastic which can be machined and worked to manufacture knives with standard tools
* zytel - a hard and durable form of nylon used to make many kinds of knives and weapons
* Blackie Collins CIA Folder. There is no steel whatsoever in this spring-assisted, folding lock knife. This assisted opening feature is made possible by a patented internal strut mechanism. The tiny springs are made from Beryllium Copper to eliminate any magnetic signature. Its handle is made from fibre resin and the razor sharp, partially serrated blade is made of 33% glass fibre Nylon 66

CIA Letter Opener
Manufactured from high-tech composite materials with over 60% glass fibres, the CIA Letter Opener's marketing blurb describes it as 'a completely non-metallic knife that provides superior plunging power as well as a hard edge. The scalloped serrations on both sides of the blade give additional opening power on fibrous materials'. For many years the CIA Letter Opener has been described as a lightweight security device capable of being driven through over 12 mm of plywood without breaking. The Cold Steel CAT Tanto, meanhwile, is marketed as being 'black, silent and totally undetectable'. The CAT, as it's known, is made from UV and heat-stabilised, glass-filled zytel nylon. This knife, with its sure-grip handle, reinforced Tanto point and skull-crushing pommel is a super-light, full-size killing tool that is invisible to metal screening devices and would probably pass unnoticed through any security checks. The CAT has all the cutting and penetrating power of its steel sisters. The Cold Steel Vietnam Delta Dart is best described as a vicious weapon designed as a covert operations last-ditch, self-defence tool. The Delta Dart is 8" long and 1/2" in diameter, yet it weighs only half an ounce! The handle is knurled for a positive grip and the butt smooth and rounded, so it's perfect for both thumb and palm reinforced grip positions. The triangular blade geometry gives it incredible puncturing ability. The Delta Dart is made entirely of 43% glass-filled zytel nylon, which is easily sharpened with a nail file. Then there's the Lansky LS17. Although marketed as a general-purpose knife, the LS17 or 'The Knife', as it is sometimes referred to, has become known as a clandestine fighting weapon. The Knife is made from ABS plastic with a 31/2'' double-edged spear point blade with a serrated edge on one side. The non-slip handle has finger grooves and a thumb rest for extra thrusting grip. The LS17 is invisible to metal screening devices.

The Ace of Spades
The Ace of Spades is a very nasty push dagger made from ABS plastic. It is an extremely robust one-piece construction, capable of massive penetration with its razor sharp, spear point configuration. Of course not all non-metallic knives are manufactured as weapons. There are many companies that use advanced ceramics to create cutting tools and products which combine elegance and strength. Ceramic products using materials such as zirconium oxide and aluminium oxide for applications requiring chemically inert, non-magnetic, non-conductive or non-contaminating materials are also perfect for general applications requiring superior edge retention or wear resistance. They're also ideal for special applications such as EOD work. Many of these weapons have been designed and manufactured for no other reason than to compromise security and endanger life. As I have said many times before in my writings and my training programmes: "You cannot rely on technology alone when it comes to weapons detection, and it makes absolutely no difference whatsoever how much sophisticated state-of-the-art detection equipment you have at your disposal... If you have not trained your personal to understand what kind of weapon they are looking for, what they could be made from or even what they look like, they will not find them!"
