I wouldn't but I know pwoplw who would.
The way I see it, I only earn a certain amount of money in my life and I intend to spend them wisely. I love hand made stuff and my uncle, who is a wood carver - just gave me two wooden bowls for my birthday that I love (made out of birch). Still, I don't think a walnut, hand made cutting board justifies the $160 price.
I have this theroy, that if you buy $160 walnut cutting boards, you don't cook often. Know what I mean?
