Ergonomic Handles
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. The Tronex® 7000
Series handle is 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 four 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 Tronex 7000 Series handle, from the joint to the end, is 4.8 inches.
In contrast, handles from competition cutters are only 3.6 to 3.7 inches.
The Series 7000's long handle forces the operator to spread the cutting force with
use by all four fingers to operate the tool. Operators may use only two or three
fingers on cutters with shorter handles. 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 force which digs into the palm, compressing nerves and tendons and reducing
blood flow. To see a photo of the handle differences go to

Ergonomic Grip
The Tronex® 7000 features, as standard, a unique double-sheathed, ESD safe, cushioned
grip. The inner sheath is a 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 Tronex 7000 cushion grip is almost always considered by operators
to be more comfortable than the hard, plastic used by competitors.
