Fish Skin Grips on British Swords?

[fernando]

So, if i get it, a bit of a puzzle is the association of shagreen ( from Turc çagri = onager's back) with wfish (ray or shark) skin. While it appears (to me), that fish skin was used in European swords, in Asia was shagreen that was used in weapons like Japanese Nihontó and Chinese composite bows during the King dinasty, this being therefore quite a few centuries old fashion.
