short spliced, or half spliced, points can also be done using CNC machining. if you mean Floating points, they are usually made with CNC, or pantograph, but are more consistent with CNC. Not all Floating points have rounded edges. I was talking to someone at SBE, and since floating points are essentially inlays, all they need to do is have the inlay be sharp, which can be made with cnc technology, and the inlay pocket be rounded, and then insert inlay into pocket, and fill gap with dark epoxy, this will only work with a dark wood thats being inlayed into. The dark epoxy will essentially hide the pocket and is camouflaged with the wood.
The more recent Joss have rounded points on the outside points, but on the inside points, they are sharp. Alot of meucci is CNC, but it doesnt mean they couldnt have used the spliced technique at one point, depends on the age of the cue i suppose.
