An arrow tip comprising a bullet body tapering from a rear end to a tip end and at least two helical grooves formed within the bullet body from the tip end to the rear end. Specifically, the invention provides amine compounds, methods for synthesizing amine compounds, and methods for inhibiting neurotransmitter reuptake. Preferably the printing sleeve comprises an intermediate photopolymer or resilient polymer layer between the outer surface of the base and the imageable surface. The catalase enzyme can catalyze the reaction of peroxide to oxygen. A top-metal is applied, which contacts the metallization at or near the edge. The product composition can also be controlled in a wide range.
