The "F" handshape can be used to show small round objects (like a small pole,
buttons, coins), and certain movements of your eyeballs.
Note: the sign "COINS" below is not a "classifier." But
suppose I used the "F" handshape to show one coin falling off a
table? Then the "F" hand shape would be a classifier
representing the coin, while the "B" handshape would be a classifier
representing the table.
