Cutting Boards

Unlike wood cutting boards, these plastic cutting boards have a textured surface that will not splinter, crack, or absorb juices and moisture. They meet NSF/ANSI standards for direct contact with food.

Stain-Resistant Cutting Boards—Stain-resistant cutting boards are treated to prevent degradation caused by the growth of bacteria.

Rotating Self-Healing Cutting Mats with Grid

Turn these pads 360° to cut material from any angle. They protect tabletops and help keep blades sharp. These pads have a rotating cutting surface and a nonslip base that holds them in place. The surface is self-healing, so it stays smooth even after repeated cuts. It’s made of tiny, compressed layers that separate around your blade as you cut, then spring back together when the blade is lifted. Use grid and angle markings to guide your cuts.
