Which of the following is NOT a type of knife commonly found in a kitchen?

A filleting knife is indeed a common type of knife used in various kitchen settings, particularly for preparing fish. It is designed with a flexible blade that allows for precision in separating the flesh from the skin and bones. The other types of knives mentioned, such as the chef's knife, paring knife, and serrated knife, are also standard equipment in kitchens, each serving specific purposes.

The chef's knife is versatile and used for general chopping, slicing, and dicing. The paring knife is typically smaller and ideal for intricate work, such as peeling and trimming food. The serrated knife, on the other hand, is distinguished by its saw-like edge, making it perfect for cutting through bread and other soft items without crushing them. Each of these knives has a well-established role in culinary tasks, further emphasizing the practicality of various knife types in a kitchen setting.
