The ultimate cutting board for quality cuttings and knife edge retention. Like the Hasegawa "FSR" series cutting boards, the "FPE" series has a wood-core structure, covered with a layer of plastic. It's light-weight, but at the same time hard, sturdy and durable. Safe for high-temperature washing, it ensures maximum hygiene in your kitchen. The cutting surface is slightly harder than the "FSR" series.   Model No. Size FPE20 - 5025 50 x 25 x 2cm( 19.7 x 9.8 x 0.8") FPE20 - 5030 50 x 30 x 2cm(  19.7 x   11.8 x 0.8") FPE20 - 6030 60 x 30 x 2cm(  23.6 x  11.8 x 0.8") FPE20 - 6035 60 x 35 x 2cm(23.6 x 13.8 x 0.8") FPE25 - 8035 80 x 35 x 2.5cm(31.5 x 13.8 x 1") FPE25 - 8040 80 x 40 x 2.5cm(31.5 x 15.7 x 1") FPE25 - 9040 90 x 40 x 2.5cm(35.4 x 15.7 x 1") FPE25 - 9045

I was wondering what is better wood or plastic for a cutting to keep your edge sharper longer,I was told that the white plastic ones dull a knife faster.
