This is a poster for a WMF knife.
As you can see, the background is quite plain and it looks like a table.
This allows the viewer to focus on the carrot and the cutting board in the middle of the poster.
Both the carrot and the cutting board are sliced.
What we can infer from this is that the knife used to cut the carrot is so sharp that it can also cut through the wooden cutting board
I believe that the carrot is used here not just because of its striking orange colour as compared to the background but also because raw carrots are quite hard.
That also implies that the knife is sharp.
At the bottom right hand corner, the caption says “Sharper than you think. The WMF Grand Gourmet knife with Damasteel blade.”
“Sharper than you think”, once again it emphasises on the fact that the knife is really sharp.
“Grand Gourmet knife” tells us that the knife is of high quality.
And Damasteel is a stainless steel with very high cleanliness.
This shows that the knife is not just sharp and of high quality but also very clean.
