CHOOSING A HANDLE LENGTH

"The Technical Source!"

A cutting tool is deemed ergonomic if it materially contributes to reducing the probability of cumulative trauma disorders with the hand, finger, wrist or arm.  Handles are designed for transferring force from the operator to the point of operation in a highly ergonomic manner.  The average American worker's hand or palm is approximately 4 inches wide. Therefore tool handles should be four inches long at least.  To allow freedom of hand placement, 4 to 5 inches would be even more desirable.  The length of the Long Handle Series from joint to end is 4.8 inches.

The long handle forces the operator to spread the cutting force with use by all four fingers to operate the tool, depending upon the size of the operators hand.  They may use only two or three fingers on cutters with shorter handles.  

For operators with larger hands, the longer handle also spreads the cutting load over the width of the palm in a bar of force.   In contrast, a short handle presents a point of fore which digs into the palm, compressing nerves and tendons and reducing blood flow (see pictures at below.)

ERGONOMIC CUSHION GRIPS - Cutters and pliers have ergonomic cushion grips surrounding the steel handles.  These comfortable grips have a no slip surface and are made from static dissipative material to be ESD safe.

All cutters and pliers feature, as standard, a unique double-sheathed, ESD Safe, cushioned grip.  The inner sheath is tough vinyl, ESD safe material which holds the leaf spring and the cushioned surface to the cutter handle.  The outer sheath, also ESD safe, provides a no-slip, cushioned surface for the operator's hand.  This is important because the slight compressibility of the cushion aids to distribute the cutting pressure more effectively.  It can even absorb sharp particles which could be imbedded in the hand.  The cushion grip is almost always considered by operators to be more comfortable than the hard plastic used by competitors.

SAFETY TIP PROTECTOR

All cutters are supplied with a unique plastic protector for the tip of the cutter.
It is easy to use, yet very effective.  The protector covers the tool when it is not being used.  
It prevents chipping of the tip from accidental dropping and can prevent the exceptionally 
sharp edges from injuring an operator.
