Karl Eickenberg, Solingen-Ohligs (Eikaso)

[Hellas]

Here's an Eikaso 5/8 with a hollowed back. Full hollow ground but quite heavy for the size.

Karl Eikenberg was founded in 1926 and produced under the brand Eikaso cutlery. Knifes are still manufactured by Eikaso in Solingen (no razors) and apparently the company is still family owned.
