Boning/Filleting Knife: As the largest of our boning knives, this 10-inch Flex Fillet Knife is the go-to knife for filleting fish, trimming fat from large pieces of meat, slicing chicken cutlets so they are paper thin, or butterflying large pork chops. With the same flexibility and strength as our smaller models, this knife features an extra long blade to cut through any piece of meat without difficulty.

Enhanced Performance: The narrow blade shape and slightly flexible design glide smoothly along bone contours, separating meat without tearing. Its tapered tip maneuvers around smaller bones and cartilage with ease. Enjoy the design, satisfying heft, and quality feel of this indispensable kitchen tool.

  • The knife is precision forged from a single piece of sturdy high-carbon German steel that has corrosion resistance and offers good hardness.
  • Optimized multi-stage heat treatment with advanced CRYO ice-hardening process for superior edge retention, hardness, durability, and flexibility characteristics.
  • Featuring a 15-degree angled blade edge, sharp heel, and smooth spine for precise cutting performance.
  • Ergonomic handle and SMART-BOLSTER™ design for comfort, control, and precision.
  • For Knives Warranty is Covered for 10 years from the date of purchase. Refer to the Warranty Policy Page for details.
