Query: Slippery

I had high hopes for this cutting board, based on the positive ratings others have given it. However, I don't like it at all. One reason is, admittedly, personal. It has rounded ends rather than being a perfect rectangle. Consequently, pieces of food get between it and the stove, next to which I put my cutting board. But, more importantly, it is very slippery due to its smooth finish. My knife slips and I have problems using my chef's knife to pick up pieces of, e.g., chopped garlic. I'm sorry to have bought it.
