I have to draw on my own experience. There is no reason not to use a custom traditional. Case and GEC make knives that cater to collectors, but that does not mean you can't use these versions if you choose because they are in every way functional knives. I personally try to use my "Sunday best" traditionals in light duty situations and to use other knives in my "accumulation" for heavy use, harsh environments, etc.
It seems that some of our modern knife bretheren take joy in using their knives in very harsh duty. Not that there is a problem with what they do; they pay their money just like I do and can use their knives how they like. I just don't do that sort of thing with any of my knives.
As far as your traditional goes, use it just like you would any knife of the same pattern, if you choose. It will work fine. You will enjoy the use of it. Let your original thoughts about why you bought it guide your use. If you bought it as a collector piece, then don't use it. If you bought it thinking you would use it, then by all means do so.
Just some random thoughts.
