Crescent Wiss has taken the Aviation Snip to the next level with the advanced Metal Master Aviation Snips. The precision-cast molybdenum blades have CNC-ground serrations which allow for more uniform serrations that provide a cleaner cut every time. The spring-action design allows for fast, effortless feed. The new generation of Crescent Wiss Metal Master will cut over 8 miles of steel and feature up to 10 times longer cut life than traditional Aviation Snips.
