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 Craft Smart.
- We flag Silicone polymer leaching (low-molecular-weight oligomers), Thermal degradation and off-gassing and Bacterial contamination and biofilm growth on the Craft Smart and not on the Fiskars.
- The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Craft Smart is silicone (gel-based), 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 →
