I liked Cody's 98.6. It is a good little book.

Whats special about Mora?
Not much.

It is just a knife.
It might be exotic in some places but they are pretty common in the north. They are the basic toolbox knife in a lot of places.
I am not so fond of the grind as some people are but they do hold a good edge once they are sharp.
The blade is thick enough to stand light prying or being driven into wood.
They are cheap enough and light enough that you can have a few extras around. The sheaths are getting better but are still pretty bad.
I think they got popularized more by Mors Kochanski than anybody else but Mors would have used whatever knife was common. What was common in northern Alberta back then were the wood handled frosts.
Every hardware store had boxes of the things. They didn't even come in separate packages.

To say they wouldn't be the choice for the forest is kind of odd because that is exactly what they were favourites for.
People working in the bush expected to have saws and axes available too for the heavier cutting so a small knife was fine.
Still, you can cut a poplar sapling about as thick as your wrist with two or three slices of a small knife if you know what you are doing.
