Eli5: why are the tips of scissors worse at cutting than the base?
In: 38
They aren’t, necessarily. Scissors are not particularly sharp – they do not cut like a knife.
Scissors cut by having the blades slide past one another, shearing the material. It only works if there’s no room between the blades for the material to slip through.
The blades are a little bit bendy, though, and the hinge isn’t perfect. Out by the tips, there is usually some room for the material to squeeze between the blades and thus escape being cut.
