This was the hilarious reaction when a man in central Germany was dumbfounded after he sharpened a knife and it glided through a piece of paper.
The footage was filmed last year (January 30) but has since resurfaced online and garnered significant attention.
The filmer explained: "I wanted to sharpen my grandmother's old knife to see the difference, I wanted to shoot a before and after video.
"I knew it was a good knife, but I didn't expect it to be so sharp!
"The surprise you see on my face.
"Old quality proves itself, I guess.
"In the end I didn't sharpen it at all."
