Functional Form Cutting Board Set, 3-Piece vs Pastry Mat: which is safer?

Where these two actually differ

• 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 Trudeau.
• We flag Silicone degradation and leaching, Odor and off-gassing and Surface wear and micro-particle shedding on the Trudeau and not on the Fiskars.
• The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Trudeau is Silicone or rubber mat, which is most of the difference in these two grades.
• We are less certain about the Trudeau grade, at 35% confidence against 72%, because it discloses less.
