Well, no one else has tried to answer your question - publicly at least. Sorry to answer a question with a question, but do you have a particular cue that you are questioning? If so, post pictures of it here, with close-ups of the area where the bottom of the points and the handle meet.
In more general terms, it's not hard to tell. Take a look at a "bar cue" or a "sneaky pete" - they are full-splice cues.
Finally, if you're asking for the difference in a full-splice and a half-splice cue, I would refer you to Google.
Hope this helps,
Gary
