Ergonomic Handle 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 for Erem Magic cutters are only 3.7 inches; handles for the Lindstrom 8100 are even shorter at only 3.6 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.

The 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.

The Safety Tip Protector
All Tronex cutters are supplied with a unique plastic protector for the tip of the cutter. It is easy to use, yet very effective. The protector "puts the tool safely to bed" when the tool is not being used. It prevents chipping of the tip from accidental dropping and can prevent the exceptionally sharp edges from injuring an operator. Some day all cutting tools will have some sort of tip protection. Tronex is leading the way.
