Welcome to the Edge, Rocket Skate’s one of a kind skate tracking system. How does it work you ask? Simple, when you pre-pay for 10 sharpenings at the bargain price of only 8 single sharpenings, you get The Edge. There’s nothing to carry which is great for kids, but even more importantly, you can tell with a few clicks on the internet just how long it’s been since your skates have been sharpened. The Edge will even email you at the interval you select to remind you that your skates are overdue. It’s just one of the ways that Rocket Skate is making the planet a better place, one pair of skates at a time.
