OK so I've avoided rails at all costs for the last couple of years I'm pretty good at boxes (270 on. 50-50's etc) but havent even attempted a rail yet. Everyone I ride with says its necessary to dull the fuck out of you edges with a gummi stone. But I live on the ice coast and want to make it to the park without sliding all over the place. Soooo is it possible to do rails consistently with sharp edges (not like race sharp but non-dulled)?
