This Fischer has maybe a couple days on it. Never seen a file, but it was ground at a shop new to be set up like .3base, 4 deg side.
It's barely over 1mm. No way was it 2-2.5mm new.
This is my pet peeve with fis sl race skis. Edges are way too thin. They can blather all they want about speed, but I think it just endures they're dead in one season. These fis sl skis list for over $1k US.
The only exception with normalish width edges I've seen is Stockli, and I don't know if they're all like that. Even Augment pooo pooed the idea of normal thickness edges when questioned here.
The picture makes the edge look even wider. Maybe it's 1.25 mm. I don't have my caliper here to measure.

Those are pretty thin. Are they very sharp hopefully? I'd have to see it in person, but for €350 prob wouldn't go for it.
