Weighing just 10.6 ounces, it strikes a nice balance between being lightweight and sturdy, making it easy to handle without compromising on control. However, the knife's flexibility, while beneficial for filleting, may not cater to all users’ preferences, particularly those who prefer a stiffer blade for tougher cuts.

On the downside, the knife is not dishwasher safe, which might be a concern for users looking for low-maintenance kitchen tools. Care must be taken to hand wash and properly maintain the blade to preserve its sharpness and prevent corrosion.

Its balance of flexibility, sharpness, and ergonomic design makes it especially suitable for filleting fish and delicate boning work.
