The 5.5 inch flexible blade offers an ideal balance of stiffness and maneuverability for precise trimming and deboning tasks.

Know before you buy
The flexibility allows the blade to follow the contours of bones and joints closely. This design minimizes waste and makes it much easier to trim silver skin or remove meat from poultry and fish with precision.
The curved bolster is designed to support the 'pinch grip,' which is the professional technique of holding the blade between your thumb and index finger. This provides better control and comfort during intricate tasks compared to a standard straight bolster.
While the knife is technically dishwasher safe, we strongly recommend hand washing. High-heat cycles and harsh detergents can dull the edge and potentially damage the handle materials over time.
A full tang means the metal of the blade extends all the way through the handle. This provides superior balance, weight distribution, and structural integrity, ensuring the knife feels sturdy and stable in your hand.
Yes, the ice-hardening process improves the molecular structure of the steel. It results in a blade that is not only exceptionally sharp out of the box but also more resistant to corrosion and better at retaining its edge over time.
