Tin whistle
In recent years a number of instrument builders have started lines of "high-end," hand-made whistles, which can cost hundreds of dollars US each — expensive in comparison to cheap whistles, but nevertheless cheaper than most other instruments. These companies are typically either a single individual or a very small group of craftsmen who work closely together. The instruments are distinguished from the inexpensive whistles in that each whistle is individually manufactured and "voiced" by a skilled person rather than made in a factory.
Nose whistle
A nose whistle (also called a "noseflute") is a wind instrument, usually made in wood, but also available in plastic, clay and sheet metal, probably of South-American indigenous origin. In spite of its ethnic background, several models have been conceived and patented in the 19th and 20th centuries. 
The nose blows air into the instrument's open nosepiece, from where it is channeled through an airduct, towards a rather sharp edge of a slit, positioned over the player's mouth opening. This edge helps creating a vortex that excites the acoustic field into the player's mouth cavity. Since the volume and shape of the mouth cavity can be widely and quickly controlled by the player, a wide range of playing frequencies are possible. This high playability of such sound instrument probably explains the fact that it is usually called "noseflute", rather than nose whistle.
