Ok, it seems the American butter knife is a deadly weapon. The butter knife I mean has a rounded tip usually not even a serrated edge and it’s basically impossible to cut anything with it. Except butter.
I always get mad when my wife mutilates a bread roll trying to cut it with a butter knife. That’s what a bread knife is for.
The reason why I prefer butter knifes is that they are much easier to get under the lid. They are only sharp enough to cut butter so you can also grab it close to the tip if you need to.
Yes, don’t use anything that can stab or cut you even if for some weird reason you call that a butter knife.
