SQUIZZERS work in the same way as ordinary scissors - but with some important improvements in design - as we will see.

As one blade moves over the other, the pressure of well honed metal pressed against metal shears the material that comes between the blades.

that bolts the blades together back at the pivot.
Here lies the greatest weakness
of ordinary scissors.

They fail because they get loose, due to wear on the rivet or screw that holds the blades together.
For every action there is an equal

To keep ordinary scissor blades together under maximum pressure to maintain the shearing action, scissors are made of heat treated steel, which makes the blades hard and inflexible.

scissors are made from heat treated steel.
Why? Because it is hard. It achieves its hardness in part from carbon, which causes scissors to corrode. And because heat treated steel is hard, it is naturally subject to fracture and has no spring in it.
are much more efficient scissors. No forging is necessary. They are made
from 300 series stainless steel, which has a natural "spring" and "memory"
The spring in the steel allows a greater shear angle between the blades, increasing the sharpness and control of the cut.

the blades to the open position when the hand is relaxed.
Thus cutting is much easier than with conventional scissors.
advantage of the "spring" steel is the increasing of the shear angle by
300%. This not only facilitates cutting, but also produces a cleaner cut
than ever before possible.
The "spring" steel will not corrode. It won't fracture.
means that the blades are less rigid than the rivet, so that shearing pressure
can be maintained for years with little or no wear on the rivet itself.
Further, the flexibility of "spring"

are easy to pick up and flex. They are ambidextrous; they fit comfortably
in the left or right hand, and are designed to the hands anatomy so they
are easy to squeeze to produce the shearing action.
And they are guaranteed.
