Staring back at the vendor, Naoto obviously wasn't going to say anything on the 'how'... because him asking 'how' that worked just confirmed his own foul.

"If you have an issue in 'how' my knife remained, you could request for some assistance determining foul play. However, I'll have to ask similarly how come none of my boyfriend's knives stuck to the board. In the same vein of thought, my knife stuck to the bulls-eye; therefore, I won a prize. I guess I'll have to ask for security since you are withholding..."

And before he might try framing this against them, Naoto raised her slate, took a picture of the winning shot, and pocketed it.
