Ice skate and ice skate blade thereof

An ice skate blade adapted to be used with an ice skate blade holder provided with a longitudinal recess, wherein said ice skate blade is removably secured, said longitudinal recess having two sides designed to be in contact with two opposed side surfaces of said ice skate blade, each one of said two sides incorporating at least two longitudinally spaced apart, transversal openings, so disposed in each one of said two sides as to be coaxial;

• said ice skate blade comprising
• an ice contacting lower curvature and an ice contacting upper curvature so as to be positionally changeable in one of two alternative working positions with respect to said ice skate blade holder;
• and
• a pair of parallel, opposed side surfaces transversally penetrated by at least two longitudinally spaced apart apertures coinciding with said at least two longitudinally spaced apart, transversal openings.

An ice skate comprising

• an ice skate blade holder;
• and
• an ice skate blade removably secured in a longitudinal recess of said ice skate blade holder, a front and a back end portions of said ice skate blade holder being curved adjacent to the extremities of said longitudinal recess as to protect, during the use of said ice skate, both of said ice skate blade, said longitudinal recess being also provided with two sides designed to be in contact with two opposed side surfaces of said ice skate blade, each one of said two sides incorporating at least two longitudinally spaced apart, transversal openings, so disposed in each one of said two sides as to be coaxial;
• said ice skate blade being defined geometrically by a longitudinal axis of symmetry, intersected centrally by a transversal axis of symmetry, said ice skate blade being provided with a lower curvature, symmetrical to and identical with an upper curvature;
• said ice skate blade being also provided with a first front-to-rear extending edge forming an ice-contacting edge, and a second front-to-rear extending edge/also forming an ice-contacting edge/, spaced and substantially parallel to said first front-to-rear extending edge, said lower and upper curvatures having each a bow-shape, so said ice skate blade's configuration is similar to an ellipse with elongated ends;
• said ice skate blade having also substantially parallel, opposed side surfaces transversally penetrated by at least two longitudinally spaced apart apertures disposed to coincide with at least two longitudinally spaced apart, transversal openings of said longitudinal recess;
• and
• restraining means inserted through said at least two longitudinally spaced apart apertures and said at least two longitudinally spaced apart, transversal openings, so as secure together said ice skate blade holder and said ice skate blade.
