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 Good Cook.
- We flag Phthalate leaching (if PVC), Odor or off-gassing and Thermal stability and heat damage on the Good Cook and not on the Fiskars.
- The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Good Cook is Flexible silicone or PVC chopping mats, which is most of the difference in these two grades.
- We are less certain about the Good Cook grade, at 35% confidence against 72%, because it discloses less.
Both products run through the same public rubric, which covers materials, coatings, brand disclosure, lab findings, and recalls, plus a beyond-PFAS hazard analysis. Grades are model-based estimates, not lab tests. How grades work →
