In my childhood home in the village, we only ever used thick wooden boards carved from oak... My father would scrape them clean with a knife every evening and they lasted for generation!!! Nowadays people are afraid of everything, but wood is a natural material that actually kills the bacteria inside it. Plastic is just artificial waste that ends up in our bodies when the knife leaves those deep grooves. Why choose something so fake when the old ways were much healthier for the soul and the body??? It makes me sad to see people replacing quality with cheap plastic. I still have the board my mother used for her famous pastries and it is perfectly clean even now after all these years... We must return to what is natural for our health.
