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 Norpro.
- We flag Silicone leaching at high temperature and Bacterial growth and maintenance on the Norpro and not on the Fiskars.
- The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Norpro is silicone or rubber cutting mats, which is most of the difference in these two grades.
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 →
