What is the best filet knife to use for skinning Perch?

A filet knife is not typically used for skinning Perch. For this task, it's recommended to use a sharp fillet knife with a flexible and thin blade, preferably between 6 to 8 inches long. Look for a knife with a curved blade that allows you to carefully separate the skin from the fish's flesh without damaging it. Some popular options include the Rapala Fillet Knife, the Bubba Blade Fillet Knife, and the Victorinox Swiss Army Fibrox Pro Fillet Knife.
