Functional Form Cutting Board Set, 3-Piece vs Bradshaw International Sweet Creations High-Temp Silicone Oven Baking 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 Sweet Creations.
• We flag Silicone degradation and leaching at high temperature, Microplastic/microsiloxane shed from torn or aged surfaces and Mold or bacterial growth if not dried completely on the Sweet Creations and not on the Fiskars.
• The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Sweet Creations is Silicone, which is most of the difference in these two grades.
