Query: Amazing piece of physics!

I love love love my old pocket Screwpull. I have owned it for probably about 10 years; it is a clear green pocket model. Sadly, it needs to be replaced this year, as the plastic on the collapsible handle is cracking and hence the handle is loose. But 10 years is pretty darn good for any product, so I am getting another one!It has never let me down and I always recommend them to people who don't already own one!
