How scissors work

SQUIZZERS are a breakthrough in cutting technology. Although "cutting" is the wrong term.

"Shears", the early name for scissors, more accurately describes how they work.

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

Two separate blades, set at a slight angle to each other, are moved against one another under pressure.

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

The pressure that forces the two blades together is transmitted through a rivet or screw that bolts the blades together back at the pivot.

Here lies the greatest weakness of ordinary scissors.

The failure mode

Scissors do not generally fail because the get dull or blunt. 

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 and opposite reaction.


 The pressure that forces the scissor blades together is transferred directly back to the rivet or screw, which suffers severe wear, due to poor mechanical advantage.

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.

Since they have no flex or "spring", the more pressure that is put on the blades to maintain shear, the more destructive pressure is transferred back to the rivet or screw.

The rivet is worn, loosened and eventually destroyed.

Heat treated vs. "spring" steel

Ordinary 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.

Squizzers are much more efficient scissors. No forging is necessary. They are made from 300 series stainless steel, which has a natural "spring" and "memory" to it.

The spring in the steel allows a greater shear angle between the blades, increasing the sharpness and control of the cut. 

The spring in the steel also returns the blades to the open position when the hand is relaxed.

Thus cutting is much easier than with conventional scissors.

A more efficient scissor

A significant 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.


Its flexibility 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" steel in Squizzers means that the shearing pressure stays constant throughout the entire shearing action.

Squizzers 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.
