Choosing a Zwilling Line
All three lines are forged in Germany from the same special formula steel and ice-hardened by Zwilling’s FRIODUR process.
| Line | Bolster and edge | Handle | Who it suits |
|---|---|---|---|
| Zwilling Pro | Curved half bolster; sharpenable from heel to tip | Triple-riveted black polymer | Cooks who use a pinch grip and want the full edge available for cutting and sharpening |
| Zwilling Four Star | Pronounced bolster that guards the fingers | Molded polypropylene with no rivets or gaps | Kitchens that value a hygienic, gap-free handle and a traditional finger guard |
| Zwilling Spectrum | Curved bolster; 12.5-degree edge per side | Jute Micarta with a steel end cap | Cooks who want the most acute factory edge of the three lines |
Keeping the Edge
Serrated edges are not honed. The points of the serrations carry the cut, so the knife stays functionally sharp for a long time; when it eventually dulls, have it sharpened on equipment made for serrations.
Care
- Zwilling rates the knife dishwasher safe but recommends hand washing; wash with warm, soapy water and dry at once.
- Cut on wood or soft composite boards rather than glass, stone or ceramic.
- Store in a block, on a magnetic strip or in an edge guard, not loose in a drawer.
