The connection of the blade to the handle has always been a weak point on Mora knives. This is generally never an issue as long as you do knife-like things with it. As a knife, used for cutting and only the lightest prying or ax work, it is entirely adequate and dependable.

If your the sort who abuses their equipment, the sort who could break an iron ball with a rubber hammer, and the sort who mistakenly take this as a point of pride, then you might try putting an edge on the leaf spring from a truck.

I used to carry a Kabar but, as you pointed out, it is heavy and much larger than any knife needs to be for job. Ironically it is also far weaker in some ways than it looks. The tool steel is far more brittle than is commonly assumed.

There are precious few times and places where weight and bulk are not an issue. More weight means you move more slowly and/or arrive more exhausted and/or have to leave something else behind. It is almost always a zero-sum game. A knife that is overly heavy or bulky than it needs to be costs you somewhere else.
