Saltus S1 burring knife: Increased safety and efficiency through touchless blade change. The newly developed Saltus S1 burring knife is an innovation in tool ergonomics. With its extremely simplified construction – consisting of only three parts – a completely new blade management has been achieved. In combination with a blade storage compartment containing up to 100 blades, it enables – within seconds – a touchless change of the extremely sharp blades in the work environment. The safe storage of the blade within the knife contributes to the demand for safe day-to-day industrial operations.
