EASY SAUSAGE / Easy sausage

Want open a sausage skin by hand? This is not an easy task. But for my EASY SAUSAGE, it is an easy thing to do. You only need one hand to pull, just like peel a banana, you can enjoy a delicious sausage.
The principle is like this. To tear apart two sheets of paper, One is flat, the other has a crease in the middle. You will find the crease one is apart along the crease regularly, another is irregular.
I designed this sausage skin is not completely flat，it also has a crease.This crease will more thin compared to other places. So when you pull, the sausage skin will open along the crease.
