Primarily for dry trimming, the P2 was designed as an enhancement of the Piranha blade providing for 3 separate cutting functions.  Slightly thicker blade for increased durability and longer teeth with wider spacing for better reach make it more effective and versatile than the previous version.  The concave tooth configuration from the base allows for more effective volume trimming as it syncs to the natural contour of the flower.  Longer teeth at the tip allow for increased precision when spot trimming just as scissors would do.  Additionally, the gap between the base teeth and the tip allow for small stem cutting up to about 1/8".
