Could you please find out for us the ref. numbers in question, so that I can already check with our production department prior to my trip to Bangkok?
This would be most important in order to find a solution as quickly as possible. Basically it is no problem to produce the serrations on the handles more blunt, it is just 1-2 grindings more during production.
In regard to the elevators, it is possible to produce them more sharp, but we have to know the models.
