WMF knife ads series is one of smart ads I ever saw. Its agency used a kind of humor exaggeration to display audience how sharp their knives can be.
If you look carefully, you will find the seeds in following three fruits are cut into half.
The following three try to display how thin slice the knife can cut: They are so thin that even bee/ant/spider can lift the slice.
Honestly, I am not really get what following ads try to convey. Try to say the knife can do elegantly fruit carving? Any way, they are still visually beautiful. Hence I still put them there. Maybe you guys can tell me what the ads try to tell its audience.
