Wood cutting boards generally offer a better grip than plastic cutting boards, especially when slightly damp, making them safer to use.
The safety of a cutting board depends on several factors, including its material, maintenance, and how it interacts with the knife. In terms of grip, wood cutting boards tend to perform better than plastic. This is because wood, particularly hardwoods like maple or beech, has a natural texture and slight porosity that provides more friction. This increased friction helps prevent the cutting board from slipping on the countertop and also helps keep the food being cut from sliding around on the board itself. Plastic cutting boards, especially those that are smooth and new, can be quite slippery, increasing the risk of accidents. While some plastic boards have textured surfaces, they often don't provide the same level of grip as a well-maintained wooden board. Furthermore, the type of feet or lack thereof on the cutting board also plays a crucial role. A cutting board with rubber feet will always be safer than one without.
Place a damp paper towel or a non-slip mat underneath your cutting board, regardless of the material, to prevent it from sliding on the countertop. This is especially important for plastic cutting boards, which tend to be more slippery.
