Every time I trim my fingernails, I always find myself needing to complete some minor task that would be a whole lot easier with longer nails!  Seriously, it's like a universal rule or something.  Anyway...

...one such task is opening aluminum cans.  Those tabs are impossible to grip without at least some length of fingernail to wedge underneath.

But now I've found a way to ensure I get to my tasty canned beverage as quickly as possible, not matter how short my fingernails are; and it's all thanks to our old friend, the binder clip!
