Zwilling Four Star 7-inch Flexible Fillet Knife

A fillet knife needs length to cross a fish and flex to follow its frame. The Zwilling Four Star 7-inch flexible fillet knife has a long, slender blade for running along the backbone and under the skin, so fillets come off whole and uniform.

Beyond fish, it trims silver skin and cuts thin slices from larger cuts of meat. The molded polypropylene handle is comfortable through a long session at the board and leaves no gaps for fish scales or juices.

To skin a fillet, start at the tail, angle the edge slightly toward the skin and push forward while pulling the skin back; the flex keeps the edge flat against it.

For boning poultry and pork, the Four Star flexible boning knife is shorter and easier to steer. Our guide to knife shapes compares fillet and boning knives.

    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.

    LineBolster and edgeHandleWho it suits
    Zwilling ProCurved half bolster; sharpenable from heel to tipTriple-riveted black polymerCooks who use a pinch grip and want the full edge available for cutting and sharpening
    Zwilling Four StarPronounced bolster that guards the fingersMolded polypropylene with no rivets or gapsKitchens that value a hygienic, gap-free handle and a traditional finger guard
    Zwilling SpectrumCurved bolster; 12.5-degree edge per sideJute Micarta with a steel end capCooks who want the most acute factory edge of the three lines

    Keeping the Edge

    German stainless at this hardness responds well to honing. A few light strokes on a honing steel before each use keep the edge aligned; sharpen on whetstones or a guided sharpener when honing no longer restores it.


    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.
