| 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.) |

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. |
