ZWILLING Pro 5.5-inch Razor-Sharp German Flexible Boning Knife, Made in Company-Owned German Factory with Special Formula Steel perfected for almost 300 Years, Dishwasher Safe

Excellent quality. I trust the Americas Test Kitchens reviews and this knife was their top pick for a boning knife. They tested for handle comfort and just the right amount of flex for bonune fish and cleaning all of the meat from a poultry carcass.. The knife meets all of those qualities. The construction is outstanding. Yes, you can buy a cheaper knife, but this will last for decades when taken care of properly.
