Help identify stone?

[name]

Hello all,

So I did some searching on the site, the stone I have seems to most resemble those that have been identified as Thuringians. Anyone agree?

Color is light green, size is 7" x 1.5" x 0.5", it's a fairly soft stone and it put a whoppin' edge on both a carbon steel Case knife and one of my razors.

The first pictures are of the side I've been flattening (still some to go), dry and then wet, and the third picture is the backside, dirty and beat up.

Thanks all,

n
