Since it is the traditional nature of a return spring to provide greater resistance the more it is compressed, this has been a challenge for ergonomists whose goal is to make work easier and safer. The solution lies in Lindstrom's new, patent applied for, BioSpring®, where the material and design work together to provide new characteristics.
Tension is kept minimal and limited throughout the working cycle of the tool. Handle width is controlled for ease of tool pick-up and handling. Tension and opening width can be adjusted to suit your preference via three different ports.
