I checked and the 1983 Buck catalog showed the 107 with "Buckarta" handles and the 1984 catalog also lists it with Buckarta although the picture clearly shows the new Pakkawood. This tells me that they were made with pakkawood in 1984 and maybe earlier. I know, I'm a genius! Ha!
The Empress Trio was not in the line during this time but was it was thought that sales would improve if we could get the cost down. So they reintroduced it and each knife was made like the Scout...no guard, pakkawood handle, called the "Buck Trio". They appeared in the 1990 catalog and they came in a less expensive display box. The shortest knife in this set is shorter than the 107 unlike earlier Empress Trio sets. 1993 was the last catalog that had the Buck Trio set and not very many sets were made.
Also making a comeback in 1990 was the Steak Knife set. To bring down costs, the knives were made as described above and there were only 4 knives in the set instead of 6.
