Query: TOO TOUGH to open if same one from Pottery Barn...

We received the Pottery Barn Cocktail Shaker as a gift, and if this is the same model (it certainly LOOKS just like it)as another reviewer said, but sold under a different brand, it should be BANNED! It is virtually IMPOSSIBLE to open it to clean it. The small round top cap can be coaxed off...grrrr...but opening the container requires a MAN, A KNIFE, AND A LOT OF ATTITUDE.We still have this cocktail shaker, although I should have returned it as soon as we had used it once.I constantly debate whether to just THROW IT OUT. Better to skip the martinis than to battle with this incredibly poorly made product. A jelly jar would be better than this. Be warned!
