Two of National's custom serrated rules, both 4.6 and 2.7 Tooth were designed to cut plastic bags. By precisley spacing the teeth, these products allow hand holes to be formed with exactly half a tooth left on each side of the rule at the joint. To improve longevity, these products can be Titanium Nitride coated or edge-hardened using National's exclusive system. 

Though originally designed for a specific application, the sharpness of the tooth and variety of sizes available make these products an excellent choice for cutting foam or film.

• Available center or side bevel.
• Can be coated to improve life.
