Hi. If you search the past messages on GMB you will find links to modern Czech makers - Beranek being an important one, with around 50 different designs of paperweight in the last 10 years or so. Google Beranek glass or Beranek paperweights and you will get links to relevant products.
Regarding cutting, it is done by people rather than machines, so it can vary. And the cutting pattern is sometimes determined by flaws in the glass that the maker wants to remove, rather than a design concept, so the precise shape changes.
