Repair question, loose main blade

I have collected a fair number of cub scout camping knives. Some are in great shape and others, not so much. As I remember my cub scout years they were always tight nail-breakers.
So, I have a couple that opening the main blade is somewhere between an Opinel and a Straight Razor. This is on more than 1. However, one that I will be looking at first is so badly abused that the interior liner lock for the bottle opener looks like it was torn off with a vise grips. As well there is some side to side blade play. So this one will be completely dis-assembled.

I have some guesses, and perhaps this one will answer them, but what is the usual approach to a slipjoint that doesn't actually walk or talk? As stiff as these things are new, I am imagining that some well-intentioned father or scout leader decided to somehow make a new knife easier for his scout to open. Perhaps some grinding compound in the joint, or some pressure against the spring and a hammer to seal the deal, or perhaps some heat applied in just the right place with a torch.
Worst case is that I have to remake a spring, I get that. However, what else should I be looking at? Could I possible use a crinking step to add more tension to the existing spring, or even just a wrench and a vise.

I realize that I will know so much more once it is all disassembled, but I thought I might ask anyway. I have never seen a knife so easy to open before, and all of the sudden I have 3 of them, all at the same time, and the same kind of knives as well, so perhaps this is a known issue. I'd have to double check, but I am pretty sure they are all Camilus.
 
Wear, and lack of lubrication.
There are people who will weld up worn tangs. I'm not one of them.
 
Besides the blade tang, the pivot pin is often worn to a much smaller diameter. You will see this when you take it down. A new pin often solves the problem. Sometimes you have to ream al the holes up a tad for a larger pin.
