Abstract
Abstract An ice skate has a blade and a shoe support formed with three downwardly directed extensions spaced from each other along the length of the blade. The blade of the ice skate is formed with a first projection formed at the front end thereof and extending towards the shoe support and a second projection extending towards the shoe support and located in the middle of the blade in the lengthwise direction. These projections are provided with respective plates adapted to be secured to the shoe support by means of screws extending into the holes formed in the shoe support. Such structure of the ice skate blade permits one to utilize the similar shoe support for the ice skates and roller skates.
