Zandstra Delta Competition

The Zandstra Delta Competition are replacement blades designed for Swedish ice skating, offering a specialized setup for those skating on natural ice or prepared tracks. These blades fit onto skates without cross-country bindings, catering specifically to traditional Swedish skating styles.

These blades feature a 23-meter radius profile, enabling smooth, long glides and maintaining stability at higher speeds. Constructed from bi-metal steel, they combine a hard inner core with a tougher exterior layer, which helps maintain a sharp edge and offers enhanced wear resistance—qualities that matter when you're covering longer distances on varied ice conditions. With a hardness rating of 64 Rc, the steel holds its edge well, reducing the frequency of sharpenings without becoming too brittle.

The 23-meter radius refers to the curve of the blade: a larger radius produces a flatter profile for greater glide efficiency, while a smaller radius gives more maneuverability. Bi-metal construction means two types of steel are bonded together, leveraging the strengths of each—such as edge retention and resilience. The hardness score of 64 Rc, measured on the Rockwell scale, indicates a balance between durability and ease of sharpening, so the blade keeps its edge through multiple outings.
