Joseph Joseph Slice and Sharpen Chopping Board 5 "Excellent board and knife sharpener" Mr Selway 24 May 2017 We have had this chopping board for over 1 year and it is excellent. After years of using cheaper boards we have found this one is superior in every way. The board has a raised edge to trap liquid and in no way is a problem. As you can see from the photos. it is perfectly suitable for chopping with any knife length. We also find the knife sharpening facility is very good and works perfectly - two functions for the price of one!
