Know before you buy
The blade is engineered with a high degree of flexibility, allowing it to glide along the backbone of a fish with minimal waste. The 6-inch length provides the necessary maneuverability for delicate tasks, while the 14-degree edge angle ensures clean, effortless cuts.
Because the handle is made of natural wood, it should be hand-washed and dried immediately; never submerge it in water or place it in the dishwasher. Periodically applying a food-safe wood oil will help maintain the finish and prevent the oak from drying out over time.
While it is designed primarily for filleting, the high-grade chrome-molybdenum-vanadium steel and full-tang construction make it quite robust. However, the blade's flexibility means it is not intended for heavy-duty tasks like cutting through bone or frozen foods, which could damage the thin edge.
The full bolster provides a smooth transition between the handle and the blade, which adds weight and improves the knife's overall balance. It also acts as a finger guard, offering extra safety and stability during precise cutting motions.
The hollow grind creates a thinner edge profile, which reduces friction as the blade passes through fish flesh. This design allows for smoother, more precise slices compared to a standard flat grind.
