Know before you buy
The semi-flexible blade offers enough give to follow the contours of fish bones closely, minimizing waste, while remaining rigid enough to provide control during precision cuts. It is designed to balance the maneuverability needed for filleting with the stability required for general prep work.
No, this knife is not dishwasher safe. The high-carbon steel blade and wood handle should be hand-washed and dried immediately after use to prevent corrosion and protect the integrity of the handle material.
A 60 HRC rating indicates a very hard steel, which holds a razor-sharp edge significantly longer than standard kitchen knives. Because the steel is hard, it is best maintained using high-quality whetstones rather than pull-through sharpeners, which can be too aggressive and damage the blade.
Yes, the handle is crafted from water-repellent wood. While it is designed to withstand the moisture of a kitchen environment, it is still recommended to keep the handle dry and avoid soaking it to ensure it lasts for years.
While specifically engineered for filleting, the 7-inch length and semi-flexible design make it an excellent choice for trimming silver skin from meat, deboning poultry, or performing delicate slicing tasks that require a thin, nimble blade.
