The Rhinoreto team launched the 6.5 Inch Fish Fillet Knife after extended research, so you can get the most out of your every filleting and fish cooking experience. The stainless steel blade has the perfect curved shape and length of 6.5 Inch and can be used for filleting all freshwater and saltwater fish species from pan-fish, walleye to salmon and many more. We have selected a balanced stainless steel for the blade, so that it will resist corrosion and offer the right amount of flexibility at the same time. Best fish fillet knife: - flexible, curved blade with special coating - non-slip, ergonomic rubber handle - sharp edge & effective blade sharpener The Rhinoreto Fish Fillet Knife packs these in one sharp offering. We hope you will enjoy using it. Important notice: 1. Keep in mind that due to the softer nature of stainless steel alloys, these blades offer higher corrosion resistance but they tend to lose their edge faster, depending on the frequency of use. It's important to use the included sharpener to restore the sharpness of the blade when needed. It's extremely easy to use - just pass the blade between the plates while pressing it down gently and repeat the movement until you feel the edge is sharp again. 2. We recommend you wash the knife by hand. 3. Always wipe the knife's blade with a towel after rinsing it and make sure it's completely dry before storing it in its sheath. 4. Rhinoreto Fillet Knife is a precision instrument meant for fish filleting only, so please avoid using it to cut heavier or thicker bones. This is a sharp product, handle with care. Not suitable for children.
