Zwilling Pro 5.5-inch Flexible Boning Knife

A flexible boning knife bends to follow the curve of a bone, which leaves more meat on the cutting board and less on the frame. The Zwilling Pro 5.5-inch flexible boning knife has a narrow blade with a fine point for starting cuts and enough flex to trace around chicken thighs, pork ribs and fish.

It is also the knife for removing silver skin from a pork tenderloin: slide the tip under the membrane, angle the edge slightly up and draw along the length. The Pro curved bolster keeps the grip secure when hands are 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, and the narrow blade turns easily around a hip joint or a wishbone.

For filleting whole fish, the Pro 7-inch fillet knife has more length. Our Kitchen Knife Shapes guide explains stiff and flexible 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.

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

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.
