This is a lovely set of 12 pieces of Swedish Cutlery from the Swedish Stainless Steel manufacture Gense. All 12 pieces are from the Thebe design that was designed by Folke Arstrom in the 1940's and I believe still in production to day. In this set are

3 knives 19.5 cm 
3 knives 18.5 cm
3 forks 18 cm 
3 forks 17.5 cm 

All are in very good condition and do appear hardly to have been used. please see photos for condition.
