I have seen a flurry of posts about copycat stoppers and patent violations, and I am not adding to that thread.
I have yet to turn a bottle stopper, but I was planning to try one soon - probably Ruth's due to the good comments. I have seen long ones, short ones, stainless and chrome. (also cork and plastic)
What is different about her stopper? Does it fit more types of bottles? Does it seal better? What is patent-able about her design - form, fit, function?
Or, asked another way - why would someone copy it?
Just curious.
