There is a difference between a user and a collector, although interference is common.
The user (as the name implies) uses each and every pice he owns.
When the user makes the transition to the collector he starts to buy pieces he will not use - in the sense of the primary use of the knife.
He uses it by putting it into his collection and is happy to own it, show it, whatever.
When you use pieces of your collection, then your question arrises.
From what I understand you have already used it, so you can continue doing that.
If you want a certain model preserved you should have bought a double or used another one instead.
That said it is not easy to predict the future value of a knife today. Just look at the well used Kabar's of the II WW.
As for the future fate of any collection, proper documentaion and education might help the next generation to enjoy it wisely.
