I have this folding knife that my grandpa gave me long time ago but I dont know anything about it,
It says on the blade, original frenix mark pocket dagger, and on the other side, on the bottom of the blade says D.R.G.M. patente org. The blade size is aprox 3.5"
Thanks

This appears to be a old issued German Naval seaman's pocket knife.
