13" Semi-Transparent Polymer Cutting Board vs Functional Form Cutting Board Set, 3-Piece: which is safer?

Where these two actually differ

• We flag Plastic polymer leaching under heat stress and Bacterial colonization in surface damage on the Cuisinart and not on the Fiskars.
• We flag Microplastic shedding from cutting action, Bacterial biofilm accumulation in deep cuts, Staining and odor retention and Heat-induced warping or leaching on the Fiskars and not on the Cuisinart.
• The Cuisinart is semi-transparent polymer (likely polyethylene or polypropylene) where the Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed, which is most of the difference in these two grades.
