* are similar to poison gas-both are barbaric
  - the most powerful in the world, but public opinion decides whether they are used
* can only destroy huge numbers of existing human beings.

### device | instrument | weapon:

Biological weapon
* Most biological weapons cause death.
* are a disgrace to biology
  - also illegal
  - among the most dangerous weapons in the world today
  - an ethical and scientific abomination, a disgrace to biology
  - germs
  - lethal, ideal for surprise attack, and have tremendous psychological impact
  - natural, including bacteria or viruses
  - pound for pound the most potent weapons that exist
* are relatively cheap to make and wantonly destructive
  - inexpensive and easy to produce
* are the massive new threats of the twenty-first century
  - poor countries weapon of mass destruction
* can be hard to make and use, contrary to myth and claim
  - be, and most reliably are, delivered by ballistic missiles
* have a number of very attractive features for terrorist uses.
* pose grave dangers.

### device | instrument | weapon:

Blade
* Most blades have handles
  - surfaces
* Some blades also employ twisting along their length, again to optimize lifting efficiency.
* Some blades generate energy
  - wind energy
  - grow from bottoms
  - have veins
  - kill wolves
* also break when the metal fatigues from use, or simply because they get dull
  - can give off sound, which is another way fish locate food
* are cuts of beef
  - flakes which are at least twice as long as they are wide, with relatively parallel sides
  - impulse hardened for long lasting sharpness
  - inch thick hardened steel, radius cut so they keep their full length when sharpened
  - leafs
  - like leaves
  - located in figure skates
* are part of chucks
  - fans
  - helicopters
  - hockey sticks
  - ice skates
  - knifes
  - lawn mowers
  - oars
  - propellers
  - saws
  - swords
  - turbines
  - windmills
  - razor sharp
  - ribbons
  - runners
  - steel, damascus steel or obsidian
  - structures
  - upright and tend to slow rate at which water moves through a region
* are used for cuts
  - cuttings
  - slits
  - young people
* can cut through different materials
  - shade each other and reduce evaporation
* differ in the number of teeth and the angle at which they protrude from the blade.
* have surfaces.
* includes hilts
  - knife edges
  - sections
* perform dual functions
* provide traction.
* sucking damage appears as brown lesions where the blade s sap was removed by the insect.
+ Saw, Power saws, Jig saws: Cutting tools :: Woodworking tools
  * Jig saws move the blade up and down to cut through materials. These saws are very good for making curved cuts. Jig saws use a variety of interchangeable blades for cutting different materials. Some blades make very smooth cuts.
  * A 'blade' is the flat, sharp part of a tool or weapon used to cut or stab, such as a knife or sword. Most blades have handles. Blades can be used to stab, cut, or separate things. It can also be the top part of grass or the leaf of a plant. Blades come in all different sizes and shapes, sharpness and materials.
+ Tanto: Japanese swords
  * At that time the tanto was not just a weapon but also a work of art. Blades become thinner and broader and thus even more dangerous. Different styles developed and the shape changed.

### device | instrument | weapon | blade:

Anvil blade
* are most efficient for dry, hard and old growth.
* have a straight upper blade that cuts against a broad, flat blade.

Ceramic blade
* are also ideal in applications where high speed, rapid cut processes are required
  - an ideal cutting product for applications that involve high heat levels
* can chip and break easier than steel blades if they are abused.
