The largest number of instruments needed by falconers to look after birds with are related to surgical remedies for different diseases. Some of them were those used by surgeons and barbers, such as llancetes, raors, pinces, tenalles, tisores, fill i agulles (lancets, razors, tweezers, scissors, needles and thread). They were used to make incisions, extract things or close wounds, among other operations. Besides these instruments there were ferros or cauteris (cauteries), common in medieval surgery, but adapted in shape and size for use on birds of prey.
Some of these objects, however, were specifically designed and made for curing and looking after birds of prey, such as tenalles dels caçadors (hunter’s pincers), made to cut the talons and the beak and keep them the right length and shape. Fine metal needles, with special characteristics, were other objects used specifically by hunters and falconers. They were used to repair broken feathers, to join the piece at the end to the remaining part of a broken feather. In the Catalan sources these needles were called agulles d’escatir (imping needles), since escatir was the term used to refer to grafting feathers (imp) as a procedure for repairing them. The whole set of instruments was often kept in a case (estoig) that prevented the pieces from being scattered; they could also be carried comfortably, and be available whenever needed.
