Safety rulers are specially designed cutting guides that protect hands and fingers during trimming, scoring, or slicing tasks. Featuring built-in hand guards or raised edges, they provide a secure barrier between the cutting blade and the user. Ideal for use with craft knives, rotary cutters, and utility blades, safety rulers ensure straight, accurate cuts while significantly reducing the risk of injury. Made from durable materials like aluminum or stainless steel, they often include non-slip backs and measurement markings for precision and control. Perfect for schools, studios, and workshops, safety rulers combine accuracy with essential protection.
