Zwilling Four Star 5.5-inch Flexible Boning Knife

Deboning poultry, pork and fish is a matter of following the bone, and a flexible blade bends to do that with less waste. The Zwilling Four Star 5.5-inch flexible boning knife has a long, thin blade that traces the contours of a chicken thigh or a pork shoulder and separates meat from bone and skin cleanly.

It is also the right knife for silver skin and fat cap trimming. The pronounced bolster acts as a finger guard, which matters on a knife used with a firm grip and some force, and the molded handle keeps a secure hold when wet.

Work with the tip against the bone and let the blade flex rather than levering it. Short, controlled strokes leave the most meat on the trimmed cut.

For filleting fish, the Four Star 7-inch fillet knife is longer and more flexible. Our Kitchen Knife Shapes guide explains 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

    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.
