If you were to ask me, there are 3 manufacturing types of cues:
Production Cue- more than 1 cue made in accordance to manufacturer's specifications and aims to target a general or specific market
Semi-Custom or
Production Customized Cue - any existing (readily-available) production cue in which the "stock" or existing specification(s) has/have been modified in accordance to a specific customer's specs (Ex. reduction of shaft diameter, change of wrap, engraving of name, addition of inlays or marks, etc)
Fully Customized Cue -any cue made from scratch in accordance to all of the specific customer's specs (choice of materials, ring design, balance point, length, weight, taper, etc)
LIMITED CUES can any be of the 3 manufacturing types:
Ltd Production -limited number of cues made for the public
Ltd Semi-Custom -limited production cue which has been modified to a specific person's specs
Ltd Full Custom - 1 or several identical-looking cues made from scratch in accordance to all of the specs of a particular customer
A fully customized cue will always remain a fully custom cue since it's been built for a specific person in mind.
Manufacturing technique can either be handcrafted or machine aided. Either way, I don't think it determines the level of customization
Again, this just how I describe them
