A bird's beak knife is a knife with a specialized curved blade that is well suited to things like carving fruit and producing the “tournee cut,” which is often used in food presentation. While this type of knife is not a vital necessity for most kitchens, it can be a very handy tool. A number of companies produce bird's beak knives, made from an assortment of materials for cooks of different needs. Most kitchen supply stores carry at least a small assortment.
Viewed from the side, the blade of a bird's beak knife really does resemble the curved beak of a bird. The blade is usually shorter than that of a paring knife, although it can perform many of the same functions. The curved blade can also make it a very useful utility knife around the kitchen, since it can perform a number of kitchen tasks.
An alternate name for the knife is a “tournee knife,” in a reference to the tournee cut that can be accomplished with a bird's beak knife. A tournee cut is any sort of shaped cut in food that results in a sculpted piece of fruit or vegetable. Such cuts can be relatively mundane or extremely complex, as in the case of Thai fruit carving, which turns whole fruits into elaborate displays of knife work. Many people find that a bird's beak knife is the ideal tool for this job, since the short curved blade can get into places where other blades cannot.
When selecting a knife, look for one that feels right in your hand. As a general rule, try to avoid purchasing knives in a set, since you will often acquire those that you do not need. The knife should fit in your hand comfortably, and it should have solid, strong construction. Blades are usually metal, although ceramic is also available. You can usually find solid molded knives or knives with plastic or wooden handles. A solid molded knife will hold up longer, and is generally the best choice.
Care directions for a bird's beak knife vary, depending on what type of handle it has. As a general rule, never run kitchen knives through a dishwasher, as the blades can become damaged. Wash the knife in soap and warm water, and dry it thoroughly to avoid spotting or pitting the blade. Store knives in a safe location out of the reach of children and curious pets.
