Individual countries have their own rules, and while some items are unambiguously permitted or forbidden everywhere, quite a few are in a greyish area which varies from country to country (and then there are the items which are in the very grey area where no-one is really sure and it will depend on who you stumble upon).
In the case of Dubai, TSA rules ...
(Not so much worried about the scissors but the ability to have confidence in knowing what can be taken in carry-on bag; you read and follow the rules and then get ripped off at the officers' discretion anyway).
Unfortunately this is a basic fact of flying these days. While there are rules and regulations, security officers have wide leeway and discretion. ...
I have just received a response from the airport which pretty much answers the question:
