Since there is no ONE knife fit all purposes, I am adopting the concept of survival "multi--tool". I am now looking for a fixed blade sheath that will take two smallish knives ( one straight edge and one serrated)

I never like the partailly serrated knives. If they are small then each section is too small for anything. If the knife is big, well, I may have problems using it in urban environments. And since I am 99% in urban environment, I may not be able to use it at all. Two small fixed knives seem a better way to go for my case.

Have you seen any sheath for two small knives?

BTW,I have seen sheaths holding one big knife and another smaller one. But what I am looking for is a sheath that holds two knives of similar sizes side by side.
