Hi,
I found this 7-day set at a cutlery store near my house. This is a 7-day set, in a nice box. Blades appear to be 4/8, round point. Scales look like plastic. I checked all of the blades and they are in good shape. The spines are engraved with the day of the week. The tang says "Tennis Soligen", the blade has goldwash which says "Facharbeit Soligen". If anybody is interested in this, send me a PM and I'll forward the store's info.
