The Zandstra 3M Polishing Triangle is the final step to a truly fast edge. After you sharpen, this tool polishes the gliding surface of your speed skating blades to a mirror shine, cutting friction so the skate carries speed for longer. It uses genuine 3M lapping film in several grades on a purpose made aluminium triangle.

How it works

The triangle carries self adhesive 3M lapping film strips loaded with micro aluminium oxide. Working through the grades, from coarse to fine, brings the steel to a very shiny, glassy surface. A polished blade glides better and holds its edge longer than a freshly ground but unpolished one, which is why serious skaters finish every sharpen with a polish.

What is included

The triangle comes complete with three grades of film already fitted, ready to use.

• 40 micron, blue: the first, coarsest polishing stage
• 30 micron, green: the middle stage
