A double-edged skate blade assembly for an ice skate comprising a double-edged blade and a pair of blade supports, each of which is individually replaceable. The assembly includes mechanisms to mate the blade supports about the blade, to connect the blade supports to each other, to interlock the blade and support assembly into a blade holder on the skate and to fasten the blade assembly to the blade holder. The entire blade assembly is easily removable, reversible and replaceable in a skate with little or no requirement for tools. The invention also comprises a holder to securely support the skate blade assembly on the boot of the ice skate.

1. A removable double-edged blade assembly for an ice skate having a boot and a blade holder attached to said boot, said assembly comprising: an elongated skate blade having a pair of opposed ice-contacting edges, and a plurality of apertures through said blade between said opposed ice-contacting edges;a plurality of elongated blade supports, each having: an inner surface;an opposed outer surface; andat least one alignment means on said inner surface, adapted to align with at least one of said apertures and to removably mate said blade supports with said blade;wherein said alignment means and said inner surface are inseparable; andwherein said outer surface is removably seatable within said blade holder, such that said blade holder covers a portion of said blade and a portion of each of said blade supports; andat least one set of coaxial passageways in said blade and said blade supports to accommodate a fastener to connect said blade and said blade supports to a corresponding coaxial passageway in said blade holder. 2. The blade assembly of claim 1, wherein said alignment means comprises one or more projections on said inner surface, each of said projections being adapted to mate with one of said apertures. 3. The blade assembly of claim 1 wherein said alignment means further comprises connecting means to connect said blade supports to each other. 4. The blade assembly of claim 3 wherein said connecting means comprises studs on one of said blade supports and corresponding cavities on another of said blade supports. 5. The blade assembly of claim 1, further comprising means to removably interlock said blade assembly to said blade holder. 6. The blade assembly of claim 5 wherein said means to interlock said skate blade comprises teeth on said outer surface of at least one of said blade supports to correspond to teeth on said blade holder. 7. The blade assembly of claim 1 further comprising at least one expandable sleeve insertable in said passageways to accommodate said fastener. 8. The blade assembly of claim 1 wherein said blade comprises one or more inset sections to accommodate said blade supports. 9. The blade assembly of claim 1 wherein at least one of said blade supports further comprises at least one impact distribution surface on said outer surface of said blade support, in contact with a lower edge of said blade holder, to absorb impact transmitted downwardly through said blade holder. 10. The blade assembly of claim 9 wherein said impact distribution surface comprises a ridge parallel to a longitudinal centreline of said blade support. 11. A skate blade holder for an ice skate comprising: an upper platform to be attached to said ice skate;opposed sidewalls depending from said upper platform and terminating in a lower edge;a substantially planar groove between said opposed sidewalls at said lower edge to accommodate a removable double edged skate blade assembly comprising: an elongated skate blade having a pair of opposed ice-contacting edges, anda plurality of elongated blade supports such that said blade supports separate said blade holder from said blade along said blade supports;at least one set of coaxial passageways in said blade holder to accommodate a fastener to connect said blade and said blade supports to said blade holder; andat least one interlocking means within said groove adapted to interlock with a corresponding interlocking means on at least one of said blade supports, such that said blade holder covers a portion of said blade and a portion of each of said blade supports;wherein said interlocking means comprises at least one set of teeth corresponding to a set of teeth on an outer surface of at least one of said blade supports. 12. The blade assembly of claim 11 further comprising at least one expandable sleeve insertable in said passageways to accommodate said fastener. 13. An ice skate with a double-edged skate blade assembly, comprising: an elongated skate blade having a pair of opposed ice-contacting edges, and a plurality of apertures through said blade between said opposed ice-contacting edges;a plurality of elongated blade supports, each having an inner surface bearing at least one alignment means adapted to align with at least one of said apertures and to removably mate said blade supports with said blade, said alignment means and said inner surface being inseparable, and an opposed outer surface;a blade holder to removably secure said blade and blade supports to said ice skate by removably seating said outer surface within said blade holder, such that said blade holder covers a portion of said blade and a portion of each of said blade supports; anda set of coaxial passageways in said blade, said blade supports and said blade holder to accommodate a fastener to connect said blade and said blade supports to said blade holder. 14. The ice skate of claim 13 wherein said blade holder further comprises: an upper platform to be attached to said ice skate;opposed sidewalls depending from said upper platform and terminating in a lower edge;a groove between said opposed sidewalls at said lower edge to accommodate said double edged skate blade assembly; andat least one interlocking means within said groove adapted to interlock with a corresponding interlocking means on said outer surface of at least one of said blade supports.
