Only the man who works manual work was there and he showed me the plywood in boards some 2,5 meters by probably 1,5 meters or so and he had no idea about what plywood that was, nothing of its characteristics but he said: "Look, we have no pieces of plywood simply because we do not cut plywood here, only sell the borads, because it spoils the knives and one sharpening costs some 75$; you can speak with the woman at the counter, she's the boss, but I doubt that she will allow it.
Fine, excellent idea, how much is that?
I didn't find the right solution from the internet.
