I have a Helle Fossekallen (sort of a cross between the Eggen (handle) and Fjellkniven (blade). I'm really a fan of the shaped birch handle and while it might be a little small wearing gloves, I think the inclusion of a guard is important considering how ridiculously sharp the blade is and the fact that having that added bit of safety might help the knife be a bit more versatile (e.g. the ability to safely make draw cuts and push cuts).
The tang on mine does go all the way through the handle where it is peened over at the end, but it's not "full tang" where the blade stock is sandwiched between the handle scales. The knife is, however, quite stout and very sturdy and I've never felt like I had to be extra careful with it and it seems like it would take a lot to break anything. That said I think it's sort of a nice knife to go smashing through blocks of wood and I've heard that the blades can be bent with too much torque (the outer steel laminate is very corrosion resistant, but soft).
For its intended purpose, I love it. Functional and beautiful, and the Fossekallen sheath includes a keeper strap attached with a snap. Seems to me like a lot of the blades would be on the short side for batonning anyhow, the majority being around 4". I couldn't recommend it enough for fishing/hunting, carving/whittling, and general use and they are very lightweight (it's probably around the same as my Victorinox Soldier) but for splitting wood, well, I'd hate to break or bend mine.
