I'm fine with a puukko or brukskniv, 10 cm carbon steel blade (thickness vary depending on task and blade geometry), wood or birch bark handle and leather sheath with liner.
I prefer barrel shaped handle as they give the greatest possibility of grips and confort during use.
For a start I too suggest a Mora.
The one in your link has a kind of yatagan styled blade. The yatagan was an ottoman knife or short saber used from 16th century.
Yeah lots of people are recomending a mora, ill get one to play with for a couple months while I collate the gear and intelligence I still need.
I tried searching yatagon and ottoman on heinnie but it came up with no matches
