Hopefully your replacement will be solid.

Glad you were able to get one. The downside to GECs selling out the way they do is that there’s no guarantee there will be a replacement available if you experience an issue that warrants returning a knife.
Out of curiosity, I took out a few other GECs with catch bits to take a look at them. Some seem to solidly stay in place (35s from 2016-17, 2023 BF 34), while others have some movement. My 68 White Owl from 2021 can be moved back and forth a bit with some pressure. The catch bit on my 46 Whaler can be
very easily moved by just running the tip of a finger over the end of the bolster. And this 32 Engineer from this year can be moved quite a bit, as you can see here.
Now the big difference between these other knives and the 81 is that they all have rounded bolsters, while the 81 has square bolsters.The square bolster seems to be what causes that little piece of the catch bit to actually stick out and catch your finger; the same part of the catch bit on the round bolstered knives continues to follow the curve of the bolster and never sticks out proud like that, which is why I’d never have noticed they moved, because it doesn’t (as far as I can tell) create any sort of problem.
Of course, I’m far from an expert on catch bits. I have a general understanding of how they work and the purpose they serve, but I’d be curious to hear from a knife maker who knows more about this sort of thing to find out if movement is normal, what would cause it, etc.
I think
ken erickson
has posted some good info on catch bits before (I’m pretty sure it was a post of his that helped me understand ‘em a while back).
Perhaps he might be willing to throw in his two cents.
