Brass radial pin. Steel joint on the butt side, phenolic joint material, wood threads. The taper on the shaft is conical, which is what he says they are.
Not sure how I can be less vague. It's all opinion and all opinions are vague. Let me see what I can say that might help. While practicing, I find that I don't have to compensate as far when applying english to the cue ball. The sound from the hit is a soft thump sound and I feel some feedback(vibration). The handle area is thinner than most cues I have picked up, Not a lot and it does not have any effect on my play, my wife likes it, as it fits her hand better.
If a person has been using low end cues, then the cue will be a great upgrade, if they have been using a $200 dollar cue from a reputable cue maker, then probably it will come out even or less, depending on the person. If I had a team and they were using $100 dollar cues, I would buy his cues for them. Again, this is all opinion, this is still vague most likely. Keep asking and I will keep trying to answer you.
