I am just back from the slopes and I saw an edge tuner
someone used which I found very well made.
It looks like a regular angle plate, but had a hand screwed
knob that holds a round aluminium disk on which the
abrasive paper is glued.
You can just change the glued paper to replace the
Unfortunately, I did not get the manufacturer, and it
is supposed to be a brand new product.
Does it ring any bells?
