The stag KA-BAR peanut in the below pictures has no snap on the main blade. I am not talking about a weak snap, but absolutly no snap. The other KA-BAR is bone and I use it as a reference since it is from the same time period. After looking over the stag peanut I have come to three conclusions as to what has happened to the main blade snap.

1. the tang of the main blade has been worn down so much that the tang puts no pressure on the backspring, but that doesn't seem likely because the blade should have also shown signs of being worn, but it is almost a full blade.

2. the knife made it out of the manufacturer this way, which I find hard to believe but it could have happened.

3. the blades have been replaced. I usually doubt blade replacements because the time and effort to do it isn't worth it on knives selling at these price points. It makes no sense, but from the below pictures you can see gaps between the liners, backsprings, and stag handles. The tangs also don't line up well with the backsprings in the open position. Comparing those details to the bone handled KA-BAR it looks like the two knives were made by different companies at different times.

I don't know what happened here, but I know I usually buy knives with no snap because others pass them up, and usually it only takes repeated steps of oil, wipe, oil, wipe, and they snap like gators after a few days. But this stag KA-BAR is not getting its snap back anytime soon and I am curious as to how this happened. Any input would be appreciated.

This picture shows how the backspring should rise in the half position, but obviously the backspring isn't rising on the stag peanut.

This picuture shows how worn the tang of the main blade is on the stag peanut. Notice how low the tang sits compared to the bone peanut.

The snapless stag peanut is missing a good bit of it's tang, and therefore is not pressing against the backspring.
In the picture below, I used the exact same size box in red to demonstrate how much of the tang is missing on the master blade of the stag knife on the left.

On the bone knife on the right, the main blade tang sticks up about half a blade width above the secondary blade's tang.
On the stag knife on the left, the main blade tang is more than a blade width below the secondary blade's tang.

It has definitely been worn or damaged beyond contact with the spring upon opening.
 
Two possibilities as far as I can see. First, the tang on the stag one is too short to put pressure ob the spring (damage? wearing?), or the spring itself has worn out at the place of the pressure which became a little thinner there like a small hole, leading to no snap. Both can be fixed but it takes some skills and a need of tools. Nice peanuts BTW.

Its plum wore out.Somebody got their moneys worth outa that one.
 
Someone used the fire out of it and didn't oil the joints, I have on old Keen Cutter that is exactly the same way.
 
Well I learned something. I didn't know it was possible to open and close a slipjoint so many times that the tang is worn to the point of not being able to snap. Makes me now think twice about doing it for fun, because it is fun to listen to that snap.
 
First I'd like to say I love the old Kabars (carried the same muskrat for 11 years)
Now why did the blade wear that much versus the spring? I,ve Rc'ed a couple of them
That weren't much over 50 if at all, one I Rc'ed the blade and spring were virtually
the same hardness. I can see a gall type situation starting easily - though that does
look like an awful lot of wear. my .02
