Edgy riding, brah.
Riding ice on dull edges sucks almost as much as having a "Where are we going?" type conversation with your girlfriend. Keep your board tuned so you can ride all day and avoid both with the OneBallJay Won Ton Edge Tool. Choose either a 90-degree bevel for seriously icy days, or 88 degrees for more mellow riding. A brass knuckles-shaped grip on the edge of the guide gives you a secure hold for doing a quick tune-up in the parking lot or in your mom's basement.
