Discman 4, the electric side-edge sharpener for skis and snowboards.
DISCOVER NOW“I used to ski
better than this.”
Your skis slip and your confidence fades. Dull edges can reduce your grip, especially on hard snow.
Before you doubt yourself:
Take a look at your ski edges.
A properly sharpened steel edge helps you grip hard or icy snow.
Schematic illustration. Technique, skis and snow conditions also affect grip.
You’ve invested in good skis. To sharpen them yourself, you want a tool that is easy to use and gentle on your edges.
You want your grip back. And you want your skis to last.
Your skis come back from the shop ready to go. As you ski, the edges lose their sharpness, often before your next service is due.
You want well-maintained edges between services, too.
Hand filing is tried and tested. But it takes time, effort and practice, especially with several pairs of skis to prepare.
Your skills still matter. The work can get easier.
How important are sharp edges? We asked skiers on the slopes and show the Discman 4 in action.
Your next edge tune.
