Ice skate blades each having a main portion and an enlarged head are cut from contiguous areas of steel stock by cuts spaced such that each cut forms the upper edge of the main portion of one blade and the lower edge of the main portion of the next blade with the head portions cut alternately from those portions of the stock extending beyond the ends of the main portions. An upwardly extending lug is secured to the upper edge of one end of each blade to extend longitudinally towards the other end and a bolt is secured to or engages the other end of the upper edge and extends in the same direction as the lug. The upper edge of the blade is received in a downwardly facing groove in a skate superstructure with the groove having a slot at one end of the superstructure to receive the lug and with the bolt extending through a hole in the other end of the superstructure and having a fixing portion on the free end of the bolt for securing the blade in the groove. The fixing portion may be the head of the bolt or a nut and is received in a cavity in an external surface of an end wall of the superstructure. The blade may be formed without the enlarged head and used in a hockey skate with the blade with the enlarged head used in a figure skate.

An ice skate comprising (a) an elongated blade having an ice-engaging edge and an upper edge opposite the ice-engaging edge; (b) a superstructure defining a downwardly facing groove firmly engaging the upper edge of the blade; (c) a lug secured to a first end of the blade to project from said upper edge in an upward direction and in a first longitudinal direction of the blade; (d) a slot in a first end of the superstructure for receiving said lug upon entry of the blade when inserted into the groove upwardly and in said first longitudinal direction, said slot including a surface engaging the lug to prevent downward withdrawal of the blade from the groove while permitting such withdrawal in the longitudinal direction reverse from said first direction; and (e) releasable securing means for securing the other end of the blade to the other end of the superstructure whereby to prevent movement of the blade out of the groove and in said reverse longitudinal direction; (f) said superstructure including toe and heel support posts extending upwardly from the blade for securing to a boot, one of said posts having a wall that forms an end wall of the superstructure, and (g) said releasable securing means including a fixing portion recessed in a cavity in said end wall whereby said fixing portion is accessible from the exterior of the superstructure without occlusion by a boot mounted on the superstructure for securing and releasing the blade, said end wall extending upwardly from the blade to the boot securing means to form a smooth end of the skate.
