Ice skate

Definition and stakes

Portrait of John Joly John Joly,  The Birth-Time of the World and Other Scientific Essays

“ A second condition essential to the art of skating is also
involved in the melting of the ice. The sinking of the skate
gives the skater "bite." This it is which enables him to urge
himself forward. So long as skates consisted of the rounded bones
of animals, the skater had to use a pointed staff to propel
himself. In creating bite, the skater again unconsciously appeals
to the peculiar physical properties of ice. The pressure required
for the propulsion of the skater is spread all along the length
of the groove he has cut in the ice, and obliquely downwards.

George Eyre-Todd,  Sketch-Book of the North

“ Here at a run over the field to the ice comes a schoolboy, as eager as if the whole day were not before him, his wooden skates clashing together as he stumbles on the molehills. Farther off a young man and a maiden are transacting in orthodox fashion the idyll of the ice, she seated on what has ordinarily been a mooring post, and holding out a dainty boot, while he, kneeling devotedly in the snow, buckles on her skate. ”
