A heavy plank and therefore stable with the added bonus of hooks underneath to ensure the maintenance and safety when cutting. I use it for raw products, the ideal being to use it for a single type of product (eg not to cross with meat and fish ...). I do not put 5 stars to the extent that its real performance will be in time (wear), since I still found quite quickly the first traces of cutting edge, so to do afterwards. However considering the price and brand, I find that the quality is quite decent.
