Ric Posted July 20 Report Share Posted July 20 I'd say it's an Akro, but more of a patch than a lazy corkscrew, IMO. Having said that, when it comes right down to it, it's not very easy to define where "patch" ends and "lazy corkscrew" begins. To me, your marble is right on the cusp of it. For me, a lazy corkscrew has to have offset seams (yours are slightly offset) and it needs to travel more than half way around the marble (yours doesn't appear to). 1 Link to comment Share on other sites More sharing options...
