That's not it (although those minis are fun). The Varusteleka store, that designs and sell the Terava knives, have a video on their Facebook site of a recent visit to the Laurin Metalli factory where all their knives are made, and it showed a prototype of a one-handed version of the big Skrama they were experimenting with. The blade looked about 8 inches long, two inches shorter than the big one, which would make the knife a modern/skrama-ish version of a leuku. Still very early stage, it looked like they had cut up one of the long handles to take out the 'bump' in the middle and glued it back together again to put it on a prototype blade...
Should be a very handy, super strong multifunctional chopper/bush knife that would make a nice combo with one of the minis. I'd start leaving hints about anniversary/Christmas presents for late 2020... ;-)
