I like them all perch but particularly the wooden handle carbon steel bladed ones. Traditional series,I think,but the blade will patina much faster than my white handle stain free DR blades.
I have the traditional as well and several others of Dexter Russel knives. They are great knives. I honestly never fillet fish with it tho. The few fish I clean is done with a mister twister electric which is very geo as well.
