Small Vintage Razor Hone / Sharpening Stone

A small sharpening stone measuring 101 x 45mm Dark blue in colour with an interesting surface pattern. The stone has hand saw marks on the end so I assume it was cut from what was a larger stone originally, some faint saw marks visible on one of the sides and the end of the stone A very fine and reasonable hard stone which has been heavily worn on the back. Top face has been lapped flat down to 400 grit diamond plate level ready for use
