I saw a product called "Edge Again" in the local store. It's labelled as Figure Skate specific (there was another one for hockey skates) and claims to be a non-motorized sharpening device which sharpens and repairs all edges. I just wondered if anyone had tried it?
Judging from the silence, I suspect that no one else here has heard of it. Until now, I've never heard of it either.
I can't tell from looking how well it sharpens, but I did make out in the diagram that there's a claim that it hones the sides of the blade at the same time as the hollow.
Without buying one, it's hard to predict its utility. I have another brand of hand-sharpener that does work, so I'm probably not going to try one.
As you say I assume it's not a popular product, and without some reliable testimonials I'm very reluctant to try it.
Various ads for this device say it sharpens all 4 sides at once, with one tusk.
What 4 sides? How can 1 "tusk" maintain and restore your particular desired hollow?
If you buy one, please tell the forum if and how well it works!
