If you are unfamiliar with the world of grinding, you are in for a treat! Grinding exposes the maximum surface area, allowing it to be utilized much more efficiently. The Titanium version offers some non-stick properties, and uses an anodizing process that changes the viscosity of the aluminum, increasing strength by about 100% and making it dark in color. If you are particularly hard on things or plan to live more than one lifetime go with the titanium. Otherwise it is a matter of aesthetic preference. Triangle Collector included.
