Hello Willyg!
I am the maker of the razor. First of all I am sorry for the inconvenience!
I would offer to tighten the pin for you, but since I live in Austria, it depends on where you come from if that is the best and fastest way to solve your problem. If you have bought it at SRD, I am sure that they will help you.
In any case, some gentle tapping should solve the Problem quickly.
If you want me to repin it or if you need some advice to do it yourself you can contact me at any time:
mail@koraat-knives.at
best regards,
Ulrik
