We created a safety level chart so Martor USA customers can know how safe each of our knives are and how they differ from each other. It is then up to managers and safety leaders to decide which level of knife is best for their specific use. As a safety manager, you can decide if you want to use all the levels of the safety chart for your business or restrict some or all jobs to safety knife categories that match your safety goals. Choosing the right tool is not just about giving one safety knife to every worker for all their cutting applications. If they use the wrong knife for the task, the knife is no longer a safe knife.
