Have a look at a Mora Garberg if you haven't already.
The Wood Jewel knives used to be as cheap as chips a few years ago, I have a few of various sizes. The ones where the stick tang protrudes from the handle are very sturdy but I have the large leuku with a hidden tang and the handle came loose. The prices have got a bit crazy for what they are, considering £90 is well into full tang territory. You could also look at some of Joker's offerings or the Condor Bushlore. I like a Nessmuk because the hump on the blade is great for scraping animal skins or birch bark without fear of the tip digging in. Take a look at the Brisa Nessmuk.
